Silane coupling agents are categorized based on their organofunctional groups, each tailored for specific applications:

Aminosilanes:

Example: 3-Aminopropyltriethoxysilane (APTES).

Applications: Epoxy resins, phenolic resins, and coatings requiring strong adhesion.

Epoxysilanes:

Example: 3-Glycidyloxypropyltrimethoxysilane (GPTMS).

Applications: Epoxy-based composites and coatings.

Vinylsilanes:

Example: Vinyltrimethoxysilane (VTMS).

Applications: Crosslinking in polyethylene and ethylene-vinyl acetate (EVA) composites.

Methacryloxysilanes:

Example: 3-Methacryloxypropyltrimethoxysilane (MEMO).

Applications: Unsaturated polyester resins and acrylic-based systems.

Mercaptosilanes:

Example: 3-Mercaptopropyltrimethoxysilane (MPTMS).

Applications: Rubber compounding and sulfur-cured systems.

Each type of silane coupling agent is designed to address specific material compatibility and performance requirements.
