With the rapid development of modern composite materials, how to optimize the interface bonding between reinforcing fibers and resin matrix has become the key to improving the overall performance of materials. GPTMS (3-glycidyloxypropyltrimethoxysilane) launched by IOTA, as a high-efficiency interface coupling agent, has shown excellent performance in the fields of glass fiber and inorganic filler processing.

The GPTMS molecule contains trimethoxysilane end groups that can form chemical bonds with inorganic surfaces, and also has epoxy structures that can react with various resins such as epoxy, polyester, and PU. This structure makes it an ideal interface modifier, which can effectively improve the dispersion and adhesion of fibers or fillers in the resin matrix.

In actual operation, GPTMS can be used to treat various inorganic fillers such as glass fiber, silica, talcum powder, glass beads, etc., to improve the surface properties of fillers, and improve the impact strength, peel strength and aging resistance of composite materials. It is particularly suitable for composite products that require light weight and high strength, such as electronic materials, building structures, wind turbine blades, and sports equipment.

According to IOTA engineers, GPTMS is flexible in use and can be used for surface modification through dipping, spraying or dry mixing. The product has passed multiple industrial verifications and has stable batch consistency and good safety in use.
