There are many explanations for the interfacial action mechanism of silane coupling agent between two materials with different properties, such as chemical bond theory, reversible equilibrium theory and physical adsorption theory. However, the interface phenomenon is very complex, and a single theory is often difficult to fully explain. Then, what are the application ranges of silane coupling agent A-112?

1. Silane coupling agent A-112 is used as RTV silicone resin and mixed silane crosslinking sealant

Silane coupling agent A-112 adds single and two-component silane crosslinking sealant to improve the adhesion of a variety of substrates, including glass, steel, aluminum and concrete. When used as silylated polyurethane polymer, the silane can significantly improve the adhesion to a series of plastics by using spursm technology.

2. Silane coupling agent A-112 as polysulfide sealant

Adding single and two-component polysulfide sealant, silane coupling agent A-112 provides good adhesion for a variety of substrates, including glass, aluminum and steel. The general dosage of silane coupling agent A-112 is 0.5-1.0% of the weight of sealant. The product has good dispersibility and can obtain cohesive cracking instead of interfacial cracking.

In addition, the use of silane coupling agent A-112 can eliminate the primer that can promote the adhesion between the coating and the coating surface.

3. Silane coupling agent A-112 is used as a plastic paste sealant

A silane coupling agent is used to improve the sealant. When processing plastic paste sealants, silane coupling agent A-112 (0.5-1.5%) is used as an adhesive, which can replace polyurethane compounds to improve the adhesion to metal substrates. In addition to increasing the adhesive strength, the appearance of the plastic paste sealant modified by silane is better than that of polyurethane adhesive. The plastic paste modified by silane coupling agent A-112 is very light in color and has no bubbles after curing.

4. Silane coupling agent A-112 as an additive for phenolic and epoxy molding compounds

Silane coupling agent A-112 is used as an additive for phenolic and epoxy molding compounds, which can reduce the absorption of water by the molded composite material. Therefore, the wet electrical performance of the product can be improved, especially at low temperature, and the performance at high temperature can also be improved.
