TIMCO Fill & Fix Expanding PU Foam B3 Gun Grade 750ml

TIMCO B3 general purpose fill & fix expanding foam is a high-quality polyurethane based expanding foam designed to give excellent thermal and acoustic characteristics. Expands up to 30 times its original volume, quick to dry and can be sawn, sanded and painted once fully cured. Ideal for filling and insulating irregular or awkward gaps where the foam can expand and fill the cavity to prevent heat loss and deaden sound.
