High Heat Resistant Pure Silicone Resin

PSR 50X is 50% solution of modified polysiloxane resin in an organic solvent medium for formulating heat-resistant coating systems. Using heat stable pigments temperature resistance coatings up to 650oC can be achieved.

Typical Application

PSR 50X is used for making coatings for chimneys, muffler, ovens, barbeques and other heat-resistant applications areas. PSR 50X can be used as a primer for any heat resistance top coats. It can be diluted with common aromatic, alcohol and ester solvents. When formulated properly it can give heat resistance up to 650oC.
