SealBoss 1570 Flexible Water Stop Foam mixed with SealBoss 15x Accelerator is a flexible hydrophobic, water-activated (hydro-active), water cut-off grout and leak-seal foam grout based on a MDI polyurethane. The resin is 100% solvent free and 100% solids. The gel-time of the product is adjustable by the mandatory adding of a certain percentage of SealBoss 15x Accelerator. SealBoss 1570 Water Stop Foam is NSF/ANSI 61 Drinking Water Contact Approved.
Upon contact with water SealBoss 1570 Water Stop Foam reacts to a flexible foam while expanding its volume 30 to 40 times. The cured material is of a constant volume. Since water is not a component of the foam structure, the cured material is essentially not effected by water or dryness. The reacted material does not shrink or swell.

Advanced MDI Formulation
Depending on the amount of accelerator added and the pressure of injection, SealBoss 1570 Water Stop Foam reacts to a dense, closed cell, semi rigid material or a more open cell, semi flexible product. For best waterproofing results the closed cell structure is desired. SealBoss 1570 Water Stop Foam is designed for sealing seeping water leaks and for cutting off water in cracks and joints. Due to the low viscosity of the material, SealBoss 1570 Water Stop Foam offers superior penetration in hairline crack injection. The product is suitable for the filling of spaces, cracks and honeycombing in stone or concrete structures.
