Benefits and Application

GB-CK88E ultra-fine particle-size is a grade featuring minimal 92% in both GE brightness and particle size. It is suitable for electro-deposition coatings, printing inks, other solvent based paints and applications where ultra-fine particle size is desired. It has been dehydrated by controlled heat treatment and been highly pulverized for excellent dispersion and extremely low residue.

Due to its special performance, GB-CK88E is widely used in electro-deposition application to replace TiO2 and reduce cost while helping to shape paint film porosity and hardness. When compounding with solvents, it can improve mechanical and aging properties, enhancing film formation, density, brightness and impact strength. Because of its excellent dispersion and suspension properties, it can improve anti-sedimentation property of paints. It has low content of impurities and has high chemical inertness, low conductivity and low residue, which can contribute to salt spray resistance of E-coatings and has the least negative impact to electro-deposition paints process.

The above mentioned features also makes GB-CK88E a good product in applications like printing inks where ultra-fine particle size is desired.
