Description

Silsesquioxane Oligomer, Aminopropyl, Vinyl Terminated: 25-28% In Water, Viscosity 3-10 Cst is a unique, water-based functional organosilicon hybrid material that combines the robust inorganic framework of silsesquioxane with reactive organic groups. This dual functionality matters because it enables the creation of high-performance, cross-linked networks that enhance adhesion, thermal stability, and mechanical strength in composite materials. It is primarily needed by formulators and manufacturers in the coatings, adhesives, sealants, and elastomers (CASE) industries, as well as in advanced composites and surface modification applications.

Application

• Adhesion Promoter: Enhances the bonding of organic polymers to inorganic substrates like glass, metals, and minerals.
• Cross-linking Agent: Serves as a reactive component in silicone-based and organic polymer systems to improve thermal and chemical resistance.
• Surface Modification: Used to functionalize nanoparticle surfaces (e.g., silica, metals) to improve dispersion in polymer matrices.
• Hybrid Coating Formulations: A key ingredient in water-based, high-performance coatings requiring scratch resistance, weatherability, and low VOC content.
• Composite Reinforcement: Acts as a coupling agent in fiber-reinforced plastics (FRP) and other composite materials to strengthen the interface between fiber and resin.
• Release Coatings: Utilized in formulations for non-stick and easy-release surfaces.
• Electronic Encapsulants: Employed in protective coatings for electronic components due to its potential for thermal stability and moisture resistance.
