Popis: |
Silicone paints were prepared by mixing as-synthesized silicone resin, pigments, fillers and other additives. The effects of the solvent, addition of pearlescent powder, addition of KH550, addition of butyl titanate and temperature on the performance of high-temperature-resistance silicon paints or coatings were studied. The results showed that the optimal coating was cured at room temperature and had no cracks after 10 times cold and hot alternation in the condition of 500oC~cold water. The pencil hardness and the adhesion of coating reached 3H and 1 level, respectively. |
