Titanate Coupling Agent for Adhesives (Isopropyl Titanate)
CAS Number: 546-68-9
Titanate coupling agents are organotitanium compounds used to improve interfacial adhesion between inorganic fillers and organic polymer matrices in adhesive formulations. They reduce filler viscosity, improve wetting of mineral fillers, and enhance the mechanical and thermal performance of the cured adhesive. Titanate coupling agents are particularly effective with calcium carbonate, alumina trihydrate, and other metal oxide fillers in polyolefin-based and filled adhesive systems.
