TYTANTM Titanate Coupling & Dispersing Agent
Titanate Coupling Agents are molecular bridges at the interface between inorganic filler such as CaCO3, BaSO4, graphite, carbon black, silica and metal oxide with polymer such as PP, PE, PVC, PBT, PET, ABS and rubbers. When incorporated into polymer systems, the coupling agent could improve filler loading, pigment dispersion, impact strength hence reduce embrittlement.
Silane coupling agent only reacts with hydroxyl group on the filler surface via water condensation of silanol-siloxane process, therefore, it is suitable for glass, alumina hydroxide, magnesium hydroxide and metal powder etc. The advantage of titanate coupling agents is that they react not only with the hydroxyls but the free protons on the inorganic interface, which results in the formation of organic monomolecular layers on the inorganic surface forming the bonding for polymers.
