This 2lb Pour Foam is designed for void filling and molding applications.  It is a water blown, rigid polyurethane foam that is easy to mix by hand or by machine. Pour foam is a two-part liquid system that has a mix ratio of 1:1 by volume. It is great for buoyancy when used to fill gaps under boat decks.  It conforms quickly to voids.  The 2lb is the weight per cubic foot when fully expanded. This 2lb pour foam does not contain any CFC blowing agent or other ozone depleting chemicals.

-Pour foam will start foaming by 45 seconds and fully expand in 7 minutes.

-After mixing well, the foam will look cloudy.  Immediately pour the foam.
