Fiberglass Supply Depot 2 lb. Density Expanding Foam Kit: 2 Part Closed Cell Polyurethane Liquid Foam for Boat and Dock Flotation Insulation

Fiberglass Supply Depot Inc. 2 lb. density pourable urethane foam expands fast to fill underfloor cavities flotation chambers dock floats more for maximum buoyancy safety. This two-part liquid mix and pour foam for flotation and insulation has a simple 1:1 mix ratio that makes it easy to measure and easy to use. There’s no such thing as an unsinkable boat but if the unthinkable happens you can improve your chances of staying afloat. Density Flotation Foam is US Coast Guard approved Regulation Number 33 CFR 183.114 for flotation making it ideal for small runabouts kayaks canoes personal watercraft and pontoons. It provides 75 lbs. of flotation per mixed 2-Quart Kit and 300 lbs. of flotation per mixed 2-Gallon Kit. Use it to fill cavities under decks in forward collision spaces in hull voids and in empty compartments. This lightweight rapidly expanding foam is easy to use sets up quickly and cures at room temperature so it’s perfect for a number of marine aircraft RV industrial and artistic uses such as soundproofing thermal insulating and other non-structural applications. Mixed foam expands rapidly and tremendously by volume so prep ahead of time and be ready to pour immediately after mixing. Before you start mixing be sure to wear a proper respirator eye protection protective gloves and be sure your work area is well-ventilated. This pourable liquid foam is easy to use but it’ll stick to almost everything. To help avoid messes and ensure proper adhesion clean prep the work area before you start mixing the foam components. Once the resin and activator are combined the rate of expansion varies greatly depending on the temperature of the foam ambient air and work surface. The recommended temperature range is 75-80F for proper expansion. Keep in mind that you have only 25 seconds to mix the foam before it starts expanding so be ready!
