The enhancement effect of functional silane on products is a combination of various complex factors, such as wetting, surface energy, adsorption of boundary layers, polar adsorption, acid-base interactions, etc. The selection of efficient functional silane requires long-term accumulation of experimental, production, and application data as support.
The preliminary selection criteria for functional silane can roughly follow the following rules: unsaturated polyacetate can choose vinyl, epoxy, and methacryloxy functional silanes; epoxy resin can choose epoxy or amino functional silanes; phenolic resin can choose amino or ureido functional silanes; polyolefins can choose vinyl functional silanes; sulfur-cured rubber can choose silyl functional silanes.
The use of functional silane mainly includes surface pretreatment method and direct addition method. The former involves treating the surface of the filler with diluted functional silane, while the latter involves directly adding the undiluted functional silane liquid during the resin and filler premixing process.

It can be used as a primer for various adhesives and sealants. It can serve as a storage stabilizer for polyurethane and silicone sealants. It can act as a complex catalyst and co-catalyst for silicone sealants. It can be used as a main component in the synthesis of complex compounds. It significantly improves the bonding performance, tensile strength, and elastic modulus of various adhesives and sealants. It can be used as a crosslinking agent for adhesives and sealants, as well as an additive for high-temperature resistant silicone rubber.
Functional silanes can be used to promote adhesion between rubber and fillers, as abrasion resistance agents in specialty rubber, and for modification during rubber processing.
Functional silanes can be used as adhesion promoters between organic polymers and inorganic substrates. They can also be used as bonding components and coatings in scratch-resistant and corrosion-resistant coatings. Additionally, they can serve as dispersants for fillers and pigments, co-monomers for emulsion polymerization, water-stabilizing agents, as well as curing agents, abrasion-resistant agents, anti-corrosion agents, catalysts, and water and oil repellents in various coatings.
It can be used as a corrosion-resistant and wear-resistant primer, as well as a fingerprint-resistant top coat that is easy to clean. It can also be used as an environmentally friendly silane pretreatment.
Functional silanes can be used as adhesion promoters between inorganic materials and polymer substrates. They can also be used to enhance the mechanical and electrical properties of composite materials, as well as improve the bundling, protection, and processing performance of fiberglass.
Functional silanes can be used to improve the compatibility between resin and filler. They can also improve the dispersion of fillers and control the rheological properties of the system. Additionally, they can enhance the mechanical strength and electrical performance, reduce the expansibility and permeability of water vapor, and promote the formation of high reinforcement performance between fillers and resins. Moreover, they can significantly reduce viscosity, increase the filling amount, and improve the processing performance.
