CRL RTV408 is a neutral cure, medium modulus silicone sealant. CRL RTV408 cures to a tough, flexible rubber when exposed to moisture. CRL RTV408 offers primerless adhesion to a wide variety of common building materials. CRL RTV408 is a fast- cure elastomeric sealant that is desirable for many in-house production applications. CRL RTV408 is easy to gun and tool and is available in clear, white, aluminum, bronze, beige, tan and black. CRL RTV408 is non-corrosive to all common building components including insulating glass. CRL RTV408 has a long life expectancy and when cured, this elastomeric sealant remains flexible from -65°F to 400°F without cracking or becoming brittle. RTV408 in white or tan contains a fungicide that makes this sealant suitable for use in bathrooms, spas, and sanitary applications. CRL RTV408 is AAMA approved for exterior perimeter sealing compound and has a 20 year limited warranty. CRL RTV408, as with most major silicones, its life expectancy is still undetermined (aging tests up to and beyond 25 years have resulted in minimal changes to physical properties).
