NanoTech Materials Roof Sealant is a high quality, plasticizer-free, water-based, 100% acrylic flashing grade elastomeric coating for brush or roller application. Designed to provide a long-lasting flexible membrane that will retain this flexibility even in the harshest climatic conditions, it has excellent adhesion to most materials including masonry, PVC, polyurethane foam, concrete, metal, and primed wood. It has the unique ability to “breathe,” providing a completely watertight membrane while allowing trapped moisture to escape.
RECOMMENDED USES:
NanoTech Materials Roof Sealant is intended as a flashing material for most substrates and as a sealer for fasteners and seams in metal roofing applications only used in conjunction with fabric.

SURFACE PREPARATION:
Surfaces to be coated should be dry, free of dust, dirt, oil, loose granules, gravel, peeling coating, and other foreign matter.
COVERAGE RATE:
Apply NanoTech Materials Roof Sealant at the rate of 1.5 gallons per 100 sq. ft. (24 wet mils). Surface texture and wind will affect applied mil thickness.
APPLICATION:
This product may be rolled on a clean, dry surface. For details, see Equipment Recommendations at the end of this sheet. Apply as a flashing for most substrates. Material can be used in combination with fabric in most flashing applications. For fasteners, the fastener must be tight. Apply enough material to completely cover the fastener and form a circle of material a minimum of 1 inch around the fastener.

| Property | Value |
| Yield (1 gal to 100 sq ft) | 10 dry mils |
| Dry Time (75°F 50% humidity) | 4 hours |
| Recoat Window | >6 hrs |
| Complete Cure | 24 hours |
ENVIRONMENTAL CONDITIONS:
This product cures by water evaporation only. The product must not be applied when the ambient temperature is below 50°F or if there is any possibility it could fall below 32°F within 24 hours of application. Application is not recommended if rain or dew is likely to occur before the product dries. In high humidity conditions, late afternoon applications should be avoided as overnight dew formation on an uncured surface can cause coating wash-off.
PONDED WATER:
- NanoTech Materials coatings are not warranted to perform under ponding water.
- The National Roofing Contractors Association considers ponding water on any roof unacceptable. (See the
NRCA Roofing and Waterproofing Manual).
LIMITATIONS:
The surface must be clean and dry. Application is not recommended where ponded water is present. Do not apply over wet substrates or when inclement weather is imminent. Complete cure of NanoTech Materials Roof Sealant requires complete evaporation of water. Cool temperatures and high humidity retard cure. In addition, this product is not recommended for use without a vapor barrier in cryogenic tank or cold storage roofing applications. It is not intended for use as a thermal barrier.
