OPSZ9150 Polysilazane Resin

100% Solid Content / Room-Temperature Curing Coating Resin

CAS 475645-84-2 / Polysilazane

OPSZ9150 is a liquid polysilazane resin specifically designed for room-temperature curing and heat-curing coating systems. It is a low-viscosity 100% solid content resin that can be mixed with organic/inorganic pigments, metal powders and ceramic powders, and combined with other film-forming resins and additives. Delivers ultra-high hardness up to 9H, excellent adhesion to most substrates and heat resistance up to 750°C.
