Methyl Vinyl Silicone Rubber
We all know that silane agent can be used as a silane coupling agent. It has two functional groups with different reactivity. One of these two functional groups reacts with organic materials and the other reacts with inorganic materials. Based on this knowledge, today we will discuss the following topics: What are the uses of silane agent in different application areas?
(1) Sealants and adhesives
Sealants and adhesives have been widely used in different regions of the world. In many cases, adhesives can effectively replace welding, riveting, snails and other mechanical connections. It helps simplify the production process, reduce costs, and improve economic efficiency. Let's take a look at the advantages of silane agents used in adhesives and sealants:
Improve the adhesion and durability
High bonding performance under dry and wet conditions
Excellent dissolving power to extend its shelf life
Silane coupling agents have been successfully used in adhesive accelerators and surface treatment agents for decades because of their special structural composition. It has now become an indispensable part of coatings and ink systems, whether as an additive or as a separate primer, it makes coatings and inks with excellent performance.
Improve coating adhesion
Improve the toughness of the coating
Reduce the dispersion viscosity of fillers and pigments and improve the dispersion of pigments
(3) Glass fiber
The silane coupling agents form a chemical bond between the surface of the glass fiber and the polymer (composite matrix) to prevent moisture from penetrating into the interface between the glass fiber and the polymer, thereby increasing the transfer of stress from the polymer to the fiber.
Improve mechanical properties in wet and dry conditions
Stabilize the electrical performance
Improve the processing method of glass fiber in composite material manufacturing
Improve the elasticity and strength of thermal hollow glass fiber
(4) Resin coated sand
In the casting process of resin-coated sand, many natural and synthetic resins are used as molding sand and core sand binders. Because sand and resin have very different structures and properties, they are not easy to bond with chemical bonds, nor are they easy to penetrate and dissolve each other. Therefore, their connection is mainly through the mutual attraction between molecules on the interface. Consequently, coupling agents are usually used to enhance the bonding effect, that is, to enhance the bonding force of the interface between the resin mold and the sand grains.
The high strength of phenolic resin and furan resin was improved
Improve the mechanical strength and processing strength of casting resin
