Wildfire Shield Application & Technical Manual

3.0 Manufacturer’s Specifications

The NanoTech Wildfire Shield is a high-performance, elastomeric coating formulated with NanoTech’s patented additive used to strengthen the fire resistance of assets against wildfires or brush fires. As a result of this product’s high reflectance and high emissivity values as well as its low thermal conductivity constant, the product acts to directly protect the substrates and reduce the heat absorbed from structures exposed to impingent flames and radiant heat caused by wildfires and brushfires. With the triple properties acting as a high temperature thermal barrier, this product is highly efficient. Ultimately reducing the degradation caused by impinging flames or radiant heat onto coated materials. Thoroughly review The Safety Data Sheet (SDS) that can be found in the Appendix. The SDS contains important information regarding:

• Safety information for personnel and the environment
• First aid measures
• Chemical composition and classification
• Material handling and storage
• Regulatory and legal information
• Other relevant information

The NanoTech Wildfire Shield coating has been tested to the following standards: 1. ASTM E84 – Standard test method for assessing the surface burning characteristics of building products, including flammability and smoke density. 2. ASTM E119 – Standard test method for fire test of building construction and materials intended to rate the building materials to a prescribed temperature and time of exposure and heat transfer. 3. ASTM E162 – Standard test method for fire test response that describes measurement of surface flammability under a flame front and heat liberated by a radiant panel index. 4. ASTM E662 – Standard test method for determining optical smoke density of the smoke generated by the specimen and sampling of the off-gassing material. 5. AST G124 – Standard test method for the effects of Ultraviolet radiation on test specimen. The NanoTech Wildfire Shield coating has been tested and sampled for volatile organic compounds (VOC), resulting in non-reportable VOCs. The NanoTech Wildfire Shield coating has been tested by Caltrans personnel as applied to a timber lagging and subjected to an impingent propane torch flame for a duration of 20 min.

3.1 Wildfire Shield Maintenance

The properties that allow this coating to be effective are a combination of high emissivity, high reflectivity, and low thermal conductivity. Emissivity and reflectivity are surface phenomena that are mostly effective if the coating is directly exposed to the source of heat flux and or impingent flame and unobstructed by dirt, debris, trash, or any other material on top of the coating that may block the heat source or become a source of fuel or a flammable products such as solvents, gasoline etc. NanoTech recommends yearly inspections that will check for:

1. Wear, Abrasion, or Tears

This can be caused by repeated and or extensive abrasion of hard materials striking against the coating. An example is gravel or construction debris falling from higher elevations hitting the coating. Lifting equipment or material handling may cause damage to the coating if work is being conducted in the area and the equipment or cargo brush or strike against the coating. 2.

Cracking

This coating is manufactured with a flexible resin that will elongate with the substrates or the coated structure. Inform NanoTech of the expected movement or give for the structure being coated to ensure the elongation is within the coating’s expected parameters. The coating may crack (insert picture) in the case the structure settles or moves beyond the elastic properties of the coating. Contact a NanoTech representative for remediation procedures. Typically, the damaged area can be easily fixed with additional application of the coating. The product allows for over-layering and filling into affected areas, however, contact a representative for proper guidance and procedures. 3.

Water swelling

The product is water resistant, however prolonged water submersion (more than 48 hours) can cause water swelling and damage the product. They may occur during a flood event, for example. 4.

Vandalism

As the coating is exposed to areas that are not closely monitored and accessible to the public, it is possible that vandalism can occur.

6 Fire-Resistant Coating Application & Technical Manual

In case one or more of the events above is uncovered during inspection, or if in doubt, contact a NanoTech representative for evaluation. If possible, take detailed photos of the damage and measurements. Evaluation of the damage may require a technician to be physically present and take sample coupons for lab testing. If so desired, the coating can be cleaned with soapy water and or a power washer. Please make sure the tip of the power washer is at least one (1) foot away from the coating with a wide opening for the tip. Test in a small area first to ensure the coating will not be stripped by a concentrated water jet.

3.2 Product Preparation Guidelines

This is a high-solids, acrylic emulsion formulation that is a non-Newtonian fluid. This means that the product must be thoroughly agitated to lower its viscosity from a solid state to a liquid state. If the product is left standing in the packaging, in the application hopper machine, or in any container after agitation for more than 45 minutes, it must be agitated again to prevent its viscosity from increasing back to a solid state from a liquid state. Follow these simple guidelines: 1. Agitate the product using a helicoidal paddle and a mixer with high rpm capability for at least 10 minutes. 2. Agitate the product for at least 5 minutes and up to 10 minutes for a product that has been left standing in a bucket/drum/tote for more than 45 minutes.

3.3 Substrate Qualification and Preparation

3.3.1 Examination

Note this qualification procedure has been written for pressure-treated timber laggings. In case the product needs to be applied to other substrates, consult a NanoTech representative. Before applying the NanoTech Wildfire Shield coating, examine the surface area that will be coated, which is the product’s substrate. A thorough walk through to look for visually apparent areas of concern that may cause application issues, followed by an inspection of the entire substrate, is required. Substrate checks and preparation: Accumulation of dirt and/or debris on the substrate: 1. Applying the coating over excessive dirt and construction debris accumulated on the surface of the substrate form a layer in between the substrate and coating, which will result in poor adhesion and debonding. In a fire event, these pockets of poorly adhered product and/or de-bonded areas will serve as weak points for fire or heat penetration and should be addressed with the utmost scrutiny. 2. Identifying if the substrate is excessively dirty for proper coating adhesion is covered in the next section: Adhesion Test. 3. NanoTech recommends proper cleaning of all the sprayable surface areas, even if successful adhesion tests were conducted before the cleaning process. Adhesion tests are samples taken to ensure the coating will bond properly to the surface of the timber. As such, samples are indications and should not be used as substitute for a proper substrate surface preparation, mainly cleaning and checking for moisture. 4. Proper cleaning will encompass: a. Sandblasting for removal of all dirt/debris from the substrate’s surface or; b. Power washing for removal of all dirt/debris from the substrate’s surface. If the surface is power washed, allow the substrate to dry and follow the guidance on moisture content in the following section. c. In the case the timber lagging has been recently cleaned, an air pressure gun can be used to remove dust and light dirt. Surface Moisture Content is an important factor to consider ahead of the application of the coating. The NanoTech Fire Resistance Coating is a water-based product. The curing process consists of water evaporation in the coating to form a specified Dry Film Thickness (DTF). If the substrate is wet or contains excessive moisture, the coating will absorb the water or moisture in the substrate, and the curing time will be delayed, or in extreme cases, the coating may be damaged and not fit for purpose. Water and humidity verification: a. The coating should NOT be applied to a wet substrate. For example, right after a rain event or right after a power wash. b. Check the weather in advance and ensure you will have ample dry weather for application. The topic of favorable weather conditions is discussed in more detail in the Coating Application section. c. With your humidity tester, verify the following conditions are met: i. Humidity is less than 10% or ii. Humidity is less than 19% AND the timber will not be exposed to water. In other words, the timber lagging is not currently serving as a water drainage and will be able to dry during the application day(s) and subsequent curing days. iii. Do not apply the product if the humidity tester indicates 20% or more iv. Do not apply the product if the humidity tester indicates 19% AND the timber will be subject to water ingress and not allowed to dry.

Wildfire Shield Application & Technical Manual

3.3.2 Adhesion Test

It is extremely important that the NanoTech Wildfire Shield coating adheres well to the substrate. You can test the adhesion beforehand. Perform a peel test in test patches on all membrane substrates before applying any coating. This tests whether the substrate: 1. Is clean or has been cleaned properly for the coating application and 2. The humidity content is appropriate to conduct the work This adhesion test is a modified version of the ASTM D 903 standard and should your team should perform one adhesion test for every 1,000 sq. ft. using the following steps: 1. In no case take fewer than two samples. 2. Clean an area at least 12 inches by 12 inches. 3. Apply 0.5 mm of the coating to the specific test area. 4. While the coating is still wet, embed a 2-inch-wide polyester fabric across a test patch, leaving a 6-inch-long dry section outside of the test patch. 5. Apply a second coat to totally encapsulate flashing fabric and let it cure for at least two (2) days. The coating should be completely dry. 6. Pull the dry end of the flashing fabric at a 180-degree angle with a calibrated scale to failure of adhesion. Passing criteria: Two(2) pounds minimum resistance prior to failure. Typical resistance in timber lagging is eight (8) pounds of resistance. If the adhesion test fails, the substrate may need additional cleaning and/or removal of excessive moisture.

3.3.3 Work Area Preparation

Before applying the NanoTech Wildfire Shield coating, there are several tasks that must be performed: 1. Mask off areas with tape and protective film that are not intended to receive a coating. 2. Surface Preparation: a. Cleaning of the substrate, as discussed in the previous section b. Check for humidity content, as discussed in the previous section Check for environmental conditions and prepare accordingly Weather: ensure you have a window of a few dry days for the application of the product, which should include at least one dry day after the product is applied. Ambient humidity and dew point will increase curing time, which must be taken into consideration during the project planning process. Have all lifting equipment required and ancillary equipment for the project, such as compressors, generators, tarps, etc. Plan to have available clean water and empty drums for equipment cleaning and product deject disposal. Check city and state ordinances on disposal of acrylic water-based paints.

3.4 Use of Primers, Topcoats, or Fiber Reinforcement

NanoTech does not recommend the use of primers or topcoats, as these products may increase the flammability of the fire-resistant coated assembly. In certain conditions the use of primers or topcoats may be required. These conditions can range from constantly humid substrates; areas with ponding water, or other special unforeseen needs that require fiber reinforcement. Please discuss with a NanoTech representative before the use of any primer.

3.5 Coating Application

The overall weather conditions, substrate temperature, surface moisture, ambient temperature, relative humidity, and wind velocity affect the curing time of this product. This product cures by water evaporation only. The application requires a minimum temperature of 41°F and rising. Do not apply at temperatures greater than 120°F. Do not apply if the dew point is within 5 degrees of the substrate temperature. Under no condition is the application of this product to be exposed to rain or freezing temperatures for a period of no less than 48 hours. Apply the product in layers at 50 to 75 wet mils, building up the total dry film thickness designated by your NanoTech representative. Ensure that the applied layer is cured (dry) to the touch before applying subsequent layers. For reference, each sprayed layer will be a minimum of 20 to 50 wet mils depending on the speed of the pass. Please check with a mil gauge. There is an approximate shrinkage of 25% (according to solids content value) during curing. Before applying NanoTech Fire Mitigation Coating, ensure that all environmental conditions strictly adhere to the parameters outlined in this manual. Application outside the recommended temperature, humidity, or substrate conditions may adversely affect coating performance and safety. Any planned deviation from these specifications requires prior consultation with a certified NanoTech representative to evaluate potential risks and recommend adjustments. Adherence to this guideline is essential to achieve optimal fire-resistant properties and ensure the coating’s long-term effectiveness.
