Product Description

We have formulated this Fire Barrier Sealant to dry and form a monolithic fire stop seal that also acts as a barrier to airborne sound transmission. This Fire Barrier Sealant CP 25WB+ is a red, high performance, gun-grade, latex-based, intumescing fire stop sealant. It helps to control the fire, smoke and noxious gases during and after exposure to a fire.

This fire stops blank openings and penetrations passing through the fire-rated floor, floor/ceiling or wall assemblies and other fire-rated interior building construction. This halogen-free sealant is capable of expanding minimum 3 times its dried volume when exposed to temperatures above 1000°F (538°C). We have engineered this sag-resistant sealant to exhibit strong adhesion to a full range of construction substrates. It is applied with conventional caulking equipment, this gun-grade sealant offers an excellent caulk rate and no mixing is required. In addition, this water-based sealant is paintable as well as repairable that offers easy application and clean-up.
