Description

1-Propanamine, 3-(Triethoxysilyl)-, Hydrolysis Products With Silica is a specialized organosilane-modified silica material, representing a key class of surface-functionalized inorganic-organic hybrids. This product matters for its unique combination of a reactive aminosilane moiety covalently bonded to a silica matrix, offering enhanced compatibility, dispersibility, and adhesion promotion in composite systems. Industries requiring advanced surface modification, reinforcement, or coupling agents, such as polymer composites, coatings, adhesives, and sealants, will find this material essential for improving mechanical properties and interfacial bonding.

Application

• Polymer Composite Reinforcement: Acts as a functional filler and coupling agent in epoxy, polyurethane, and rubber composites to improve tensile strength, modulus, and thermal stability.
• Adhesive & Sealant Formulations: Enhances adhesion to various substrates (metals, glass, plastics) and improves the mechanical performance and durability of the final product.
• Surface Coatings: Used in primers and functional coatings to promote surface wetting, corrosion resistance, and paint adhesion.
• Rubber Compounding: Improves the dispersion of silica and other fillers in silicone and organic rubber, leading to better abrasion resistance and reduced hysteresis.
• Specialty Resins & Gelcoats: Incorporated into unsaturated polyester and vinyl ester resins to enhance fiber-matrix bonding in fiber-reinforced plastics (FRP).
• Catalyst & Enzyme Support: The amine-functionalized silica surface can serve as a support material for immobilizing catalysts or biological molecules.

Quality Control

Our production of 1-Propanamine, 3-(Triethoxysilyl)-, Hydrolysis Products With Silica adheres to stringent quality management protocols. Each batch undergoes rigorous testing to ensure consistency in key parameters such as amine content, surface area, particle size distribution, and moisture levels. Certificates of Analysis (COA) documenting these specifications are available upon request to support your quality assurance and regulatory compliance needs.

Storage

Preserve in a tightly closed container, protected from light. This material is hygroscopic (moisture-sensitive). Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). Keep the container tightly sealed when not in use to minimize exposure to atmospheric moisture, which can affect product performance.
