VFI®-851 Polyurethane Foam Adhesive

VFI®-851 Polyurethane Foam Adhesive is a water blown urethane foam that is applied in beads to hold down insulation panels with little pressure needed. VFI-851 has a quick rise time and cure time allowing for more square footage to be covered in a single day without the use of solvent or water based adhesive. VFI-851 Polyurethane Foam Adhesive can adhere, with great adhesion, to many different types of substrates.

Two part spray foam adhesive effectively locks down insulation panels without the use of any mechanical fasteners.
