Type Of Material
The product is a single component hydrophilic polyurethane grout. The product cures to a closed cell foam or an elastomeric gel when it comes in contact with water. The product is capable of incorporating large amounts of water that are multiples of its own mass, thereby forming a gel. The cure time of the product is determined by the amount of water added and the temperature.
While reacting to a foam the material expands its volume. 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.
