SealBoss Flexgel 2 Hydrophilic PU Grout
SealBoss® Flexgel 2 is a single component hydrophilic polyurethane grout, offering excellent penetration properties, superior strength and durability.
SealBoss® Flexgel 2 is capable of incorporating large amounts of water that are multiples of its own mass, thereby forming a water proofing gel. When SealBoss® FlexGel 2 comes in contact with only small amounts of water (up to three times by volume) the material reacts to closed cell foam while expanding. The cured material is flexible. Since water is a component of the cured product structure, the material can be effected by wet and dry cycles. The reacted material may shrink and swell as a result of the surrounding moisture content. The capability of the cured product to swell and increase in volume due to water absorption is one of the important features that discriminate hydrophilic grouts from their hydrophobic counterparts.
