Description

1-Propanamine, N,n-Dimethyl-3-(Trimethoxysilyl)-, Acetate, Homopolymer is a specialized organosilicon polymer, also known as a silane-terminated polyether, with the CAS number 90168-45-9. This advanced material is engineered to act as a highly effective adhesion promoter and coupling agent, creating durable bonds between organic polymers and inorganic substrates. It is essential for formulators and manufacturers in the sealants, adhesives, coatings, and composites industries seeking to enhance product performance, durability, and weather resistance.

Application

• Adhesion Promoter in Sealants & Adhesives: Significantly improves the adhesion of polyurethane (PU), silicone-modified organic (MS), and silane-terminated polyether (STPE) sealants and adhesives to a wide range of substrates, including glass, metals, concrete, and plastics.
• Coupling Agent for Composites: Enhances the interfacial bonding between organic resin matrices (e.g., epoxy, polyester) and inorganic fillers or reinforcements (e.g., glass fibers, minerals), leading to composites with superior mechanical strength and moisture resistance.
• Surface Modifier for Coatings: Used in primers and topcoats to improve coating adhesion to difficult substrates, increase scratch resistance, and provide long-term protection against corrosion and environmental degradation.
• Crosslinking Agent: Functions as a moisture-curable crosslinker in polymer systems, contributing to the formation of flexible, yet strong, elastomeric networks.
• Filler Treatment: Treats inorganic fillers like silica, calcium carbonate, and talc to improve their dispersion in polymer matrices and enhance the final product's physical properties.
