In the process of decomposition of silicone resin, resin disintegration, pigments, steel and other inorganic silicon crosslinking structure; Above 350℃, silicone resin completely decomposed into inorganic silicon oxygen crosslinking structure, so that high temperature resistant silicone coating "secondary film"; No matter single or double component silicone high temperature resistant paint, there is this conversion process. Part of high temperature resistant, low melting point glass powder is added to the paint when under the environment of high temperature after reaching the melting point of glass beads, glass beads can melt into a membrane, replacing the part of the organic silicon resin adhesion of the role of fillers, form a layer of loose silicide layer, make the "second film", high temperature resistant coating on substrate heat insulation and anti-corrosion effect.
Silicone thermal decomposition temperature is about 380℃,250℃ under the condition of heating for 24 hours, silicone weight loss is only 2% ~ 8%, 350℃ under the condition of heating for 24 hours, the general weight loss of organic resin is 70% ~ 99%, and silicone weight loss is less than 20%, long-term use temperature 250-260℃
Excellent low temperature resistance: can work at -70℃ for a long time, excellent low temperature resistance
