Material Notes:
GK-22 is a polyurethane gel formulation designed to make soft sticky polyurethane gel for pressure-sensitive-adhesive type products. This 2-part cast urethane system can be manually processed easily at room temperature. There is no volatile compound within the component materials and no need to dry solvent. This material cures without relying on moisture or oxygen in atmosphere to cure, so this product can be made into any thickness. Comparing to other similar formulation GK-7, GK-22 provides stronger adhesion property. GK-22 may be more appropriate where heavier object needs to be held by the gel adhesive pad, or a sufficient adhesion is required within a limited amount of gel adhesive piece.Information provided by Northstar Polymers.
