Applications of Silane Coupling Agents

Boctok silanes are mainly used as tackifiers, surface modifiers, crosslinkers, moisture absorbers and sealants in adhesives and sealants to provide the following properties: reducing adhesive viscosity, improving dispersion of fillers and pigments, improving processability and adhesion to the substrate, increasing wet and dry strength and durability of the joint, preventing premature vulcanization of the adhesive and increasing product stability during storage, improving the uniformity of adhesive vulcanization, increasing elongation at break and improving elongation at break. Improving uniformity and elongation at break.

Silane technology has attracted more and more attention as the paint industry becomes more and more stringent in terms of VOC content and the need to improve the physical properties and extend the service life of coatings. Silane coupling agent is mainly used for filler modification, resin modification and primer modification in paint, which mainly plays the following roles: improving the adhesion, water resistance, weather resistance and abrasion resistance of the coating film to the substrate, improving the compatibility and dispersion of organic resin with pigment and filler, improving the crosslinking composition of base resin, and improving the surface hardness of the coating film.

Pre-treatment technology using silane compounds is environmentally friendly and efficient. As a pre-treatment layer for a metal surface, the silane film not only improves the surface condition of the substrate and increases the adhesion characteristics between the coating and the substrate, but also serves as an independent protective coating that acts as a physical barrier against the penetration of aggressive environments.

The silane coupling agent in wire and cable is mainly used as a crosslinking agent and viscosity enhancing agent to impart the following properties to the material: improving the thermal deformation stability and mechanical strength of the modified material, improving the electrical properties of the modified material in the wet state, improving the chemical resistance of the modified material, increasing the amount of filler additive while improving processability.

Silane coupling agent can improve the bonding property of glass fiber and resin, and greatly improve the strength, electrical resistance, water resistance and weather resistance of glass fiber reinforced composites, even in wet state, it plays a very important role in improving the mechanical properties of composites.

Boctok silane coupling agents help improve the durability of building facades, bridges and other infrastructure. BKTK water- and stain-repellent silanes can be used in solvent- or water-based systems, providing the formulation flexibility needed to meet VOC requirements and be easy to use.

Boctok silanes are used in adhesives and sealants as tackifiers, surface modifiers, crosslinkers, moisture absorbers and sealants and can be used to impart the following properties to adhesives and sealants: reducing adhesive viscosity, improving dispersion of fillers and pigments, improving processability and adhesion to the substrate, improving wet and dry substrate strength and bond durability, preventing premature vulcanization of the adhesive, improving storage stability, improving uniformity of adhesive cure, improving elongation at break, improving elongation at break, improving elongation at break, improving elongation at break, improving elongation at break, improving elongation at break, improving elongation at break, improving elongation at break, improving storage stability. Homogeneity, increasing elongation at break.

Boctok silanes are mainly used as tackifiers, surface modifiers, crosslinkers, hygroscopic agents and sealants in adhesives and sealants, which can impart some of the following properties: reducing the viscosity of the adhesive, improving the dispersion of fillers and pigments, improving processability and adhesion to the substrate, improving the strength of the substrate in wet and dry conditions and the durability of the joint, preventing premature vulcanization of the adhesive and improving the stability of the product during storage, increasing the uniformity of vulcanization of the adhesive, improving the elongation at break and improving the elongation of the adhesive. Homogeneity, increasing the elongation at break.

Silane coupling agents are used in the synthesis of silicone oils and silicone emulsions to provide comfort, softness and smoothness to fabrics in the textile industry. Silicone finishing using Boctok modified silicone fluids has the following benefits: 1. Provides a soft, aesthetically pleasing feel or “hand” to the fabric with low yellowing; 2. Increases tensile strength and durability; 3. Increases water repellency (hydrophobicity) or improves water absorption (hydrophilicity), depending on the formulation; 4. Improves elasticity recovery, wrinkle resistance and abrasion resistance; 5. Reduces shrinkage; 6. Improves stretchability.

Metallic hydroxyl groups on mineral surfaces are usually hydrophilic and incompatible with organic polymers. Alkoxysilanes are naturally suited to treat mineral surfaces, making them more compatible and dispersible in polymers, and even converting fillers into reinforcing additives. In addition to plastics, the use of silane-modified minerals in organic rubbers is becoming increasingly important.
