Methyltrimethoxysilane: Guide
Methyltrimethoxysilane (MTMS) is a trifunctional organosilane coupling agent. Its three alkoxy groups enable hydrolysis, while the methyl group enhances organic compatibility.
Main Applications:
- Glass Fiber Treatment – Improves hydrophobicity, durability, and weather resistance.
- Plastic Laminate Surface Treatment – Adding 0.5%-4% MTMS enhances heat resistance, mechanical strength, electrical properties, and processability.
- Coatings, Adhesives, and Sealants – Improves adhesion and weather resistance.
