Introduction
STD8802 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℃.
Features & Applications
Features
