Relying on the directional reactivity of the single-end trimethoxysilane group and the diverse properties of the polysiloxane main chain, single-end trimethoxysilane-terminated silicone oil has been deeply penetrated into many fields such as composite materials, electronics and electrical engineering, building materials, and high-end coatings. As an interface modifier, cross-linking agent and adhesion promoter, it provides core support for the performance upgrading of downstream products, breaks the pain points of poor interface compatibility and insufficient adhesion of traditional materials, and promotes the development of related industries towards high-end and refinement.
The composite material field is its core application scenario, mainly used for interface modification of fiber-reinforced composite materials. Inorganic fibers such as glass fibers and carbon fibers have poor compatibility with resin matrices, which are prone to delamination and cracking. After adding single-end trimethoxysilane-terminated silicone oil, its trimethoxysilane groups can condense and anchor with hydroxyl groups on the fiber surface, and the polysiloxane main chain is compatible with resin molecular chains to form a stable interface transition layer. This increases the tensile strength of composite materials by more than 40%, impact toughness by 35%, and enhances the damp-heat resistance and aging resistance of materials, which is widely used in the production of aerospace composite materials and automotive lightweight components.
In the electronics and electrical field, its advantages of high insulation and directional adhesion are prominent. In semiconductor packaging and electronic potting, single-end trimethoxysilane-terminated silicone oil can be used as a modifier to improve the insulation and high and low temperature resistance of packaging materials, and enhance the adhesion between materials and chips, circuit boards, avoiding packaging detachment caused by high temperature or humidity changes, and ensuring the stable operation of electronic components. In electronic adhesives, it can be used as an adhesion promoter to solve the problem of poor bonding between organic adhesives and inorganic substrates, improve the bonding strength and weather resistance of adhesives, and adapt to the assembly needs of high-end electronic equipment.
In the fields of building materials and high-end coatings, its application value continues to expand. In building sealants, adding single-end trimethoxysilane-terminated silicone oil can improve the weather resistance, hydrophobicity and bonding strength of sealants, avoid aging and cracking during long-term outdoor use, and adapt to the sealing of various substrates such as glass and stone. In high-end coatings, it can be used as an interface modifier to improve the adhesion between coatings and inorganic substrates, and endow coatings with excellent anti-fouling and waterproof properties, reducing coating detachment and chalking, which is widely used in the production of exterior wall anti-corrosion coatings and high-end furniture coatings.
With the upgrading of downstream high-end industries, the market demand for single-end trimethoxysilane-terminated silicone oil continues to rise. The expansion of its application scenarios not only promotes the extension of the organosilicon industry to the field of fine modification, but also helps China's high-end manufacturing, aerospace and other industries break through the bottleneck of interface modification of core materials, enhance industrial core competitiveness, and its development potential in the field of high-end composite materials and electronic materials will continue to be released in the future.
