Release Date: May 5, 2026 Source: Tianyi New Materials On May 5, new material enterprise Tianyi New Materials released professional technical data, comprehensively comparing physical and chemical indexes, functional groups, applicable systems and safety notes of four mainstream silane coupling agents KH550, KH560, KH570 and MTMS, delivering clear selection references for coatings, composite materials and inorganic modification industries. All four products are colorless transparent liquids, while they differ greatly in functional groups, hydrolysis speed and application fields. KH550 amino silane boasts wide compatibility with epoxy and PU resins for general reinforcement. KH560 epoxy silane features durable adhesion, widely used in electronic potting and anti-corrosion primers. KH570 with polymerizable double bonds matches acrylic systems via free radical reaction. MTMS with methyl groups delivers hydrophobicity for sol-gel and surface water-repellent modification. The article provides targeted selection principles: KH550 for universal reinforcement, KH560 for epoxy & PU systems, KH570 for acrylic materials, and MTMS for hydrophobic & heat-resistant demands. It also reminds manufacturers of storage risks including yellowing, flammability and light shielding, helping factories cut formula test costs and improve interfacial adhesion and weather resistance of composite products.
