KBM-13
Shin-Etsu Chemical Co., Ltd. · KBM
KBM-13 is a versatile methyltrimethoxysilane alkoxy silane, specifically Methyltrimethoxysilane, used for surface modification of inorganic materials. It provides effective water repellency, improved flowability, and enhances filler dispersion, making it suitable for applications in coatings, adhesives, and sealants. KBM-13 is commonly used to strengthen adhesion between organic resins and inorganic substrates, including glass and metal surfaces.
- Good adhesion
- Improved water resistance
- Good mechanical properties
- Good weathering properties
