Froth-PAK 308900 12 Foam Sealant Kit

Dow FROTH-PAK Foam Sealant 308900 is a two-component, quick-cure polyurethane spray foam that fills cavities, penetrations, cracks and expansion joints. Unlike one-component foam, FROTH-PAK Foam Insulation is a chemically cured foam, significantly reducing curing time. It dispenses, expands and becomes tack-free in seconds. The product will skin over in 30-40 seconds and will cure in minutes.
