KBE-585 is a silane coupling agent, specifically 50% methanol solution of a hydrolysable silane, 3-Ureidopropyltriethoxysilane, used to enhance processing and performance in composites. It reduces viscosity and improves filler dispersion in thermoplastics and thermosets, especially with high filler content. It is compatible with materials like nylon, urethane, and phenolic resins, forming strong bonds between organic and inorganic materials and improving weatherability.
