NanoTech Materials Roof Sealant for Silicone Systems high-solids, single-component, moisture-cure silicone flashing grade is ready to use and offers superior flexibility for long-term crack resistance, even in high-movement applications. It has an excellent shelf life, typically requiring no mixing for up to 6 months. With excellent sag resistance, superior weathering, and exceptional water resistance in a breathable membrane, it also provides outstanding adhesion to unprimed, weathered TPO, PVC, and EPDM surfaces.
RECOMMENDED USES:
NanoTech Materials Roof Sealant for Silicone Systems is designed as a protective coating for a wide range of roof membranes, offering unmatched adhesion to unprimed, aged TPO, PVC, and EPDM, as well as excellent performance over primed cap sheet and modified bitumen membranes.

SAFE PRACTICES:
This product is designed for professional installation. Before working with this product, you must read and become familiar with the available information on its risks, proper use, and handling. Information sources include but are not limited to SDS and product labels. More resources are available at nanotechmaterials.com or by contacting NanoTech Materials directly.
LIMITATIONS:
The surface must be clean and dry. Do not apply over wet substrates or when inclement weather is imminent. In addition, this product is not recommended for use without a vapor barrier in cryogenic tanks or cold storage roofing applications or directly over modified Bitumen, asphalt, or coal tar builtup roofing systems without a sealer. This product carries Class “A” Non- Combustible and Class “B” Combustible credentials as tested under UL 790 procedures over spray foam and single-ply roofing systems.
Contact NanoTech Materials directly for more information.
CLEAN UP:
Clean spray equipment containing uncured material by flushing with VM&P, Naphtha, or mineral spirits. NanoTech Materials Roof Sealant for Silicone Systems cures by reacting with moisture. Do not leave in spray guns, pump equipment, and hoses for prolonged periods unless the equipment contains moisture lock hoses, fittings, and seals. Without these, the material will cure on hose walls and at unsealed connections possibly causing an increase in operating pressure and material flow restriction.
