SHANGHAI ZOORY CHEMICAL CO.,LTD 上海助瑞化工有限公司 Silane coupling Agent KH-551 TDS Product: Silane coupling Agent KH-551 Chemical Name: （3-Aminopropyl)trimethoxysilane CAS No.: 13822-56-5 Structure formula:(CH3O)3SiC3H6NH2 Introduction: 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. KH-551 is especially recommended to thermoplastic resins and thermosetting resins such as epoxy, PBT, polyurethane etc. It can improve reinforced plastic's physical properties and electric properties as flexural strength, compression strength and shear strength. It also can improve the dispersion and wet ability of filler in the high molecular materials. KH-551 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.
