Methyl Polysilazane STD 8802(R)
Functional additives 2025-05-14
Introduction
STD 8802(R) is a Si-H bond-containing polysilazane resin that serves as a ceramic precursor. It cures under ambient moisture or heating conditions, exhibits excellent adhesion to metals, polymers, and glass, and can withstand temperatures up to 600℃ after curing. Through ceramic conversion processes, it achieves high-temperature resistance of 1800℃.
