In the process of chemical and composite products, a formulation of titanate coupling agent 516 is often used. So what is the main substance of this preparation, and what are the uses? Let’s take a look at it with the editor below.

The main substance of titanate coupling agent 516 is phosphite polymer, which has good oxidation resistance, flame retardancy and is not easy to exchange reaction of ester substances. In industry, it is generally used as a flame retardant and antioxidant; in coatings, it can also reduce the effect of pigment baking temperature. Usually titanate coupling agent 516 is mainly used in unsaturated polyester FRP to improve the mechanical properties of FRP and enhance anti-aging properties. In addition, the dosage of titanium dioxide and solvent can be reduced in high-solid content titanium dioxide clay and epoxy coatings. On the premise of increasing the filling amount of clay, the viscosity of the system is not changed, and the adhesion to glass and metal can also be increased. In addition, when processing inorganic fillers such as metal powders, it can also improve the dispersibility and sedimentation resistance of the fillers.
