Application
Isopropyl tri(dioctylpyrophosphate) titanate (CAS No. 67691-13-8), titanate coupling agent HW-201, mainly used to treat inorganic fillers such as calcium carbonate, barium sulfate, etc, so that improved processing rheological property, higher loading of fillers, improved mechanical performance can be obtained.
It can be used to improve dispersion, hiding power and coloring power for pigments, to improve anticorrosion, water resistance, flame retardance.
HW-201 can also be used in high loading of aluminum hydroxide filled fiber glass reinforced polyester, not only preventing fillers precipitating in the liquid resin, but also improving flame retardance. Rubber products can be improved in tensile strength, tearing strength, elongation at break and aging resistance.
HW-201 can be used as coupling agent not only for inorganic fillers with resins, but also for non-polar materials with polar materials.
