CYH 500 – Single Component Hydrophobic PU
CYH 500 is a hydrophobic grout based on polyurethane.
Upon contact with water, CYH 500 reacts to closed cell rubber-like foam while expanding volume up to 27 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 affected by water or dryness. The reacted material does not shrink or swell
