Seal Boss 1640 22 Ounce Cartridge

SealBoss 1640 is a closed cell, two-component, non-shrink polyurethane foam with structural properties. This MDI (methylene-diphenyl-isocyanate) based product is 100% solvent free and 100% solids. The product starts to react when mixed and does not need moisture from external sources for the reaction. SealBoss 1640 expands up to eight times forming a closed cell structure and cutting down the material consumption drastically. The cured foam offers limited structural strength combined with increase in volume and excellent bonding properties on dry and with limitations on wet surfaces.

SealBoss 1640 is designed to fill voids in soil and stone, brick or concrete structures for the purpose of waterproofing as well as regaining certain structural strength. The excellent combination of hardness and flexibility qualifies SealBoss 1640 for use in areas where structural strength and moderate flexibility are desired.

Applications

• Leak Seal, Void Filler, Stabilizer
• Undersealing of Structures

The expanding and compressive strength qualities of SealBoss 1640 Structural Strength SlabLifter make it a price competitive alternative for the filling of voids and 'pockets'. The structural strength of the foam product is highly correlated to the expansion rate. SealBoss 1640 Structural Strength SlabLifter can be applied in dry and wet areas. Additional moisture may increase the expansion. The standard mixture expands approximately six times in volume. Job site testing is recommended to determine product suitability. To achieve most satisfying and permanent results in certain applications, a combination of SealBoss 1640 with other systems of our product line may be advised.
