What is SealBoss ® Can Seal Foam?

Can Seal Foam is a versatile, closed cell, self curing foam for universal uses. The product is a single component MDI based polyurethane of highest quality. It expands, bonds and seals while stopping the passage of air, gases, water and dust. Besides its obvious uses to stop water infiltration it can increase energy efficiency by stopping air exchange around windows, doors, wall intrusions and at sill plates. Its lightweight, closed cell structure makes it useful for deadening sound, flotation and thermal insulation. It is also useful for scaling work areas prior to stripping to prevent the transport of fibers. SealBoss  Can Seal Foam is very efficient, you get up to eight gallons foam just from one can!

The Important SealBoss Difference

SealBoss ® Can Seal Foam is specially formulated to fully expand inside the applicator ‘gun barrel’. When the foam exits the tip of the gun it is almost fully expanded – you apply exactly as much foam as you need without the messy and undesired “mushrooming” experience you may have with most of the other ‘over the counter’ foam products. This feature makes our foam predictable and suitable for many applications that cannot be performed with standard foam products. And with the  professional applicator gun you can fill voids with the exact amount of foam desired.

Contractors use our foam for many applications such as water-stop purposes in voids and cable runs, as an insulation and seal-foam in general construction and as an instant ‘Backer Rod Bead’ in applications where joints need a back fill prior to applying the final sealant.
