A flexible urethane foam designed to replace OEM foams used for sound dampening and anti-flutter applications
DURAMIX 1310 is a fast-curing, two-component flexible urethane foam designed for filling voids, gaps, and structural repairs in automotive body work. This 7-ounce aerosol system delivers precise application with a convenient 1:1 mix ratio, making it ideal for collision repair professionals who need reliable void filling and structural reinforcement.
The foam's rapid cure schedule maximizes shop efficiency with just 3-5 seconds of work time, 2-3 minutes to handling, and full paintability achieved in 10-15 minutes. Its flexible urethane chemistry bonds effectively to aluminum, bare metal, e-coat, fiberglass, FRP, OEM finishes, primer, and SMC substrates. This versatility makes it suitable for both structural repairs and cosmetic applications across diverse vehicle types and materials.
