Silane Coupling Agent KH-551 

KH-551 is an amino-functional silane that may be used over a broad range of applications to give an improvement in the bond between a substrate, filler, or reinforcement and resins that react with the amino group. It is especially recommended to thermoplastic and thermosetting resins such as epoxy, PBT, and polyurethane. It can improve reinforced plastic's physical properties and electric properties as flexural strength, compression strength, and shear strength.

KH-551 also can improve the dispersion and wet ability of filler in the high molecular materials. It is an excellent promoter of adhesion and sealant (such as polyurethane, epoxy, and phenol). In the glass wool and FRP products, it can be added into phenol resins to improve the wet resistance and mechanical performance.
