In the field of surface modification of thermally conductive fillers and functional powders, traditional long-chain alkyl silanes are increasingly falling short in meeting the stringent requirements of high-end products for weather resistance, hydrolysis resistance, and long-term stability. Changfu C1052 Polyalkoxyalkylsilane features a unique multifunctional molecular structure that overcomes the performance limitations of conventional silanes. Compared with common alkylsilanes such as octyltriethoxysilane, decyltrimethoxysilane and dodecyltrimethoxysilane, it boasts superior weather resistance, hydrolysis resistance and long-term dispersion stability. As a preferred auxiliary agent for high-performance powder surface modification, it delivers particularly outstanding advantages in the modification of thermal conductive fillers including thermal conductive silicone and thermal gel.
Product Advantages:
- Multi-functional structure design: The molecule contains two silane hydrolysis sites, achieving multi-point bonding and high cross-linking density, endowing the product with hydrolysis resistance, acid-base resistance, and durability far exceeding that of conventional long-chain alkyl silanes.
- High contact angle and dense hydrophobic layer: A low surface energy, high-density hydrophobic layer is formed on the powder surface, ensuring stability in long-term humid or medium environments and preventing agglomeration.
Product Features:
- Strong bonding not easily detached: By utilizing multi-point anchoring, the bonding strength between silane and the powder surface is significantly enhanced, ensuring the modified layer's adhesion is long-lasting and stable.
- Outstanding resistance to hydrolysis, acid-based, and salt: Forms a highly cross-linked protective network, effectively resisting acid-based salt mist, and moisture erosion, significantly enhancing medium tolerance.
- Excellent hydrophobicity and long-lasting dispersion stability: The high contact angle and low surface energy hydrophobic layer ensure that the powder is evenly dispersed in organic systems, and it is not easily caked even when exposed to humid environments for extended periods.
- Dense cross-linked structure, highly effective protection and barrier: Multifunctional structures build a three-dimensional cross-linked network, with tightly packed molecular layers, forming an efficient barrier against external moisture and corrosive media.
- Excellent aging resistance and high coating durability: Outstanding long-lasting aging resistance characteristics, perfectly suited for applications requiring long-term service and high weather resistance.
Product Applications:
- Thermal Conductive Materials: Used for modifying thermal conductive fillers in high-performance thermal conductive silicone and thermal conductive gel. It greatly improves the dispersibility and interfacial adhesion of fillers, enhances the thermal conductivity and long-term service stability of materials, and fully meets the demanding working conditions of electronic thermal components.
- Weather-resistant Coatings: Applied in powder treatment for outdoor weather-resistant coatings and anti-corrosion coatings. It boosts the coating's resistance to water, salt spray and aging, and extends the service life of paint films.
- Special Adhesives: Suitable for filler modification of high-end industrial adhesives and sealants, improving the system stability and bonding durability.
- Composite Materials: Used for surface treatment of various functional composite powders and inorganic fillers, increasing the overall strength, weather resistance and comprehensive mechanical properties of composite materials.
