KH 540 is a high-performance silane coupling agent designed to enhance adhesion and mechanical properties in thermoplastic and thermosetting resins like epoxy, polyester, and polyamide. It improves dry and wet strength, moisture resistance, and filler dispersion, making it ideal for adhesives, sealants, resin sand casting, and glass fiber applications. KH 540 also boosts pigment dispersion and adhesion to glass, aluminum, and iron.
