ISO Stearoyl Titanate contains hydrolysable – OR groups [where R is an alkyl radical such as ISO propyl] which can condense with reactive groups on the filler surface, and between hydrophobic substituents which interact with the polymer matrix. ISO Stearoyl Titanate is chemically bond to surface hydroxyl groups of fillers. ISO Stearoyl Titanate consists of hydrophobic substituents on the titanate modifying the properties of the filler surface. ISO Stearoyl Titanate can be used for coating on minerals and directly mixed while compounding with polymer- processing.
