Genesee Polymers GP-422

Genesee Polymers' GP-422 SILICONE RESIN SOLUTION is a concentrated mixture of a reactive, further curable silicone resin in an octamethylcyclotetrasiloxane carrier. GP-422 forms a continuous solid resin film, when applied to substrates and allowed to air dry. Curing to a solvent resistant coating takes place over a prolonged time period at room temperature, but may be accelerated by heating at 200°C for one hour.GP-422 is suggested for use as a binder in coatings intended for application to substrates exposed to high temperatures, and as a component of masonry water-repellent formulations.
