Product Description

1. Linear Alkyl Modified Silicone Synthetic Monomer

This product is a high-activity monofunctional alkyl chlorosilane with linear n-octyl and dimethyl composite alkyl structure. It can undergo controllable hydrolysis and graft copolymerization to introduce straight-chain octyl hydrophobic segments into silicone molecular chains. It effectively optimizes the surface lipophilicity, molecular chain flexibility and low-temperature fluidity of conventional dimethyl silicone materials, serving as a key monomer for preparing medium-long alkyl modified silicone oil and silicone resin.

2. Efficient Low-surface-energy Hydrophobic Modifier

The straight-chain n-octyl alkyl segment features low surface polarity and stable chemical inertness. The highly reactive Si-Cl bond can form firm covalent grafting with hydroxyl groups on the surface of glass, metal, silica and ceramic substrates. It forms uniform and compact hydrophobic protective films, effectively reducing surface water adhesion and endowing materials with excellent waterproof, anti-fouling and self-cleaning performance.

3. Surface Lubrication & Release Functional Additive

The linear medium-long alkyl structure provides excellent molecular lubricity and low friction characteristics. After being grafted on material surfaces or blended into polymer systems, it can significantly reduce surface friction coefficient, improve surface smoothness and scratch resistance. It is widely used in plastic molding release, precision component lubrication and anti-wear coating modification.

4. Organic-inorganic Interface Compatibility Optimizer

This monomer possesses excellent organic wettability and interface activity. It can effectively improve the interfacial binding force and phase compatibility between inorganic fillers and organic polymer matrices, eliminate microscopic interface defects, and significantly enhance the processing fluidity, water resistance and long-term dimensional stability of composite materials.
