KBE-22
Shin-Etsu Chemical Co., Ltd. · KBE
KBE-22 is an alkoxy silane coupling agent, specifically Dimethyldiethoxysilane, used to modify inorganic surfaces for enhanced compatibility and adhesion with organic materials. It is commonly applied in coatings, adhesives, and surface treatments where hydrophobicity and stability are needed. KBE-22’s ability to improve flowability and dispersion also makes it ideal for use in high-performance materials.
- Good adhesion
- Good weathering properties
- Resin compatibility
- Improved water resistance
