APS 2500

2K Acrylic Polysiloxane

APS 2500 is a two-pack isocyanate-free inorganic-organic hybrid Acrylic Polysiloxane system which can be used to manufacture coatings having superior weathering performance over polyurethane and with better mechanical and chemical performance than epoxy.

Typical Application

APS 2500 can be an ideal solution for top coat applications areas like industrial machineries, bridges, stadiums and other structures where aesthetics and performance for several years are important.
