Aminopropyltriethoxysilane (Andisil® 1100):

Aminopropyltriethoxysilane (Andisil® 1100) is one of the most versatile silane coupling agents available to today’s formulators and manufacturers. Known for its ability to improve adhesion, enhance durability, and promote compatibility between organic and inorganic materials, this specialty silane plays a critical role in industries ranging from adhesives and coatings to plastics, composites, and sealants. With its broad functionality and proven performance, Andisil® 1100 has become an indispensable tool in global supply chains where quality and reliability matter most.

What Is Aminopropyltriethoxysilane?

Aminopropyltriethoxysilane (often abbreviated as APTES) is an organofunctional silane that contains both a reactive amino group and hydrolyzable ethoxy groups. This dual functionality allows it to act as a bridge between organic polymers and inorganic surfaces such as glass, metal, minerals, and ceramics. Once hydrolyzed, the ethoxy groups form silanol groups that can chemically bond to hydroxyl-rich surfaces, while the amino group interacts strongly with resins, polymers, and other organic systems.

This unique chemistry makes Andisil® 1100 a highly effective adhesion promoter and surface modifier, improving interfacial strength and enhancing product performance across a wide range of applications.

Key Applications of Andisil® 1100

The versatility of Aminopropyltriethoxysilane allows it to serve in multiple markets. Common applications include:

• Adhesives & Sealants: Andisil® 1100 enhances adhesion to glass, metals, and mineral substrates. It improves wet and dry bond strength in silicone, polyurethane, and epoxy-based formulations.
• Coatings: As a primer or additive, it improves film adhesion to inorganic surfaces, increases corrosion resistance, and boosts durability in industrial and protective coatings.
• Composites: A critical additive in fiberglass-reinforced plastics and composites, where it strengthens the fiber-matrix interface, leading to higher mechanical performance and longer service life.
• Plastics & Rubber: Used as a coupling agent in filled or reinforced plastics and elastomers, Andisil® 1100 improves tensile strength, abrasion resistance, and dimensional stability.
• Textiles: Offers improved binding of resins to fabrics and better compatibility in specialty textile finishes.
• Electronics: Functions as a surface treatment to improve adhesion and insulation properties in encapsulants, conformal coatings, and potting materials.
