Phenyltrimethoxysilane (PTMS)

Phenyltrimethoxysilane is a functional organosilane coupling agent designed to improve adhesion and compatibility between organic polymers and inorganic substrates. The phenyl group imparts enhanced hydrophobicity, chemical resistance, and thermal stability, while the methoxy groups provide excellent surface reactivity and hydrolytic stability.

This silane is commonly used in adhesives, sealants, coatings, and composite materials, where improved mechanical properties, moisture resistance, and durability are required. It is particularly effective for bonding to glass, metals, and mineral surfaces.

Key Features:

• Enhances adhesion between organic and inorganic materials

• Improves hydrophobicity, chemical resistance, and thermal stability

• Provides hydrolytic stability and surface reactivity

• Strengthens mechanical properties and durability in composites

Applications:

• Adhesives and sealants

• Coatings and paints

• Polymer and composite materials

• Glass, metal, and mineral surface treatments
