QuanFeng YCR-9961 is a professional vinyl-modified polysilazane resin, developed with high-purity polysilazane and vinyl functional modifiers, featuring dual curing performance (heat curing & moisture curing). It cures to form a dense inorganic Si-C-N ceramic layer, delivering stable long-term protection up to 750℃ (short-term peak 900℃), excellent thermal shock resistance and superior anti-corrosion performance. This multifunctional polysilazane resin is widely used as high temperature adhesive, electronic potting compound, fiber sizing agent for carbon/glass fiber, and protective coating for metal substrates, compatible with epoxy, polyester and other resin systems, ideal for aerospace, electronic insulation and advanced composite material manufacturing.
