One-Part Smooth Finish Formula With Primerless Adhesion on Most Common Construction Surfaces Including Kynar™ Coated Metals AAMA ApprovedVOC Compliant - Only 9 g/LUV Resistant/Non-Yellowing Sealant Estimator ChartCRL M64 is a one-part, moisture curing, gun grade modified polyurethane sealant. It does not require a primer on most common construction surfaces. CRL M64 is durable, flexible, and offers excellent performance in moving joints.Basic UsesCRL M64 Modified Polyurethane Construction Sealant is specially formulated to outperform traditional VOC solvent polyurethanes for sealing moving joints in concrete, masonry, metal, and other basic perimeter joint applications. It is ideal for all joints between framing (door and window) and the building structure in both storefront and curtain wall applications to secure a watertight installation. This advanced polymer formula offers excellent adhesion to fluoropolymer paint coatings for metal surfaces including Kynar™, Duranar®, and Duranar® Sunstorm™ Coatings, as well as standard metal, aluminum, steel, galvanized steel, plastics, vinyl, glass, wood, concrete, brass, and other common building substrates. CRL M64 is compatible with insulating glass sealants when glazing units and applied as a toe or heel bead. CRL M64 is designed for exterior and interior use. Withstands temperatures after full cure from -75°F to 300°F (-59 to 149°C). Paintable after only two hours with water-based paints. It is also suitable for varied manufacturing uses, such as the production of travel trailers and mobile homes, and in the assembly of galvanized air conditioning ductwork.FEATURESExceptional adhesion to Kynar™ coated metals.VOC Compliant – only 9 g/L (Chemically curing Eco-Friendly Product – Solvent-Free, Isocyanate-Free, VOC Compliant, Qualifies for LEED Credit for Section EQ (Indoor Environmental Air Quality).Low temperature gunning and application above 0°F (18°C).Service temperature of -75°F to 300°F (-59°C to 149°C).Permanently Flexible – Will not get hard with age like traditional polyurethanes. Remains flexible in low temperatures.Fast Cure - Skins over in 30 minutes and continues to cure at a rate of 1/8" (3 mm) depth per day.Tooling time – approximately 20-40 minutes, depending on temperature and humidity. Paintable – Can be painted in only two hours with water-based paints.UV Resistant – Will not turn yellow from exposure to the sun.
