Accelerator For 1510/1570 PU Injection Foam.
SealBoss ® 1510 WaterStopFoam mixed with 15x Accelerator is a hydrophobic water-activated (hydro-active) water cut-off grout and foam seal 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 15x Accelerator. A phthalate free formulation (F) is available. 1510 WaterStopFoam is NSF/ ANSI Drinking Water Contact Approved. Upon contact with water 1510 WaterStopFoam reacts to a semi fl exible 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 eff ected by water or dryness. The reacted material essentially does not shrink or swell. Depending on the amount of accelerator added and the pressure of injection, 1510 WaterStopFoam reacts to a dense, closed cell, semi rigid material or a more open cell, semi fl exible product. For best waterproofi ng results the closed cell structure is desired. 1510 WaterStopFoam is is designed for sealing water leaks and cutting off gushing water. Due to the low viscosity of the material, 1510 off ers good penetration in hairline crack injection. The product can be used for the fi lling of voids, cracks and honeycombing in stone or concrete structures, and can be applied as a non-shrink, high strength soil stabilization grout when used with reduced accelerator ratio. The moisture content of the soil must be suffi cient to ensure reaction. To achieve most satisfying and permanent results in certain applications, a combination of 1510 WaterStopFoam with other systems of our product line may be advised.
