Polyurethane (PU) Coating for Rubber Keypads

Polyurethane (or PU) is a protective overcoat applied to rubber keypads. This clear coating provides wear resistance for very high use applications or products that are used in harsh environments. Adding the polyurethane coating to rubber keypads ruggedizes the keypad, increases abrasion resistance, adds UV resistance and prolongs the longevity of the rubber. It provides superior resistance to corrosion andchemical exposure. This particular coating is also a cost effective solution. 

PU coatings protect rubber keypads from oils, dirt, and contamination. The polyurethane may be applied in a glossy or matte finish, to meet the aesthetic requirements of the rubber keypad. The polyurethane coating is deposited on the top surface of the keypad over the printing. Polyurethane coatings are used across all industries to improve the appearance and lifespan of the materials.
