Characteristics,
TY-80-1 giving very high opacity,high whiteness, fine particle,good dispersion,little residue on 325 mesh sieve, super whiteness,good light dispersion,fluidity and chemical stabillity,donot react with other solvents,good floatability against sedimentation. TY-80-1 is a very effective opacifying extender, partially replacing TiO2, reducing the overall cost of paint formulations but maintaining paint film quality.It can improve the properties of paints such as scrub resistance, abrasion endurance,ageing resistance and stability during storage.
Application
Widely used in high-quality paints such as emulsion paint,powder coating,oily paint etc.
