CYH 500 Single Component Hydrophobic PU

Product Description

Upon contact with water, CYH-500 reacts to closed cell rubber-like foam while expanding its 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. Depending on the pressure of injection, CYH-500 reacts to a very dense material or foam.

Advantages:

• Negative side application possible
 
• Deep penetration into very small cracks
 
• Foam increases in volume to fill cavities and voids
 
• Excellent bond to surfaces
 
• Good adhesive strength, tolerant of movement
 
• Inert after curing, constant volume, no shrinkage
 
• Does not create new cracks
