Rheological agent | YRFC-RG02A | Amber clear liquid | Oil-based | With a small amount of 0.1-0.2% can effectively solve the powder sedimentation; Increase the addition amount to 0.6-2%, which can quickly form thixotropy and can be used for anti sagging coating on vertical or slope surface. |
Viscosity Reducer | YRFC-11 | Brown clear liquid | Oil-based | It is applicable to coatings with high powder filler content. Only a small amount of powder filler can be added to disperse and adsorb on the surface of a large number of powder particles, effectively reducing the adsorption between powder particles, achieving the purpose of reducing the viscosity of the system, improving the leveling, reducing scratches, preventing the accumulation and hardening of powder filler, and reducing the defects of paint film such as brush marks, orange peel, pinholes, etc. The viscosity can be reduced by about 70% by adding only 0.1-0.2% of the system powder; For some extremely high viscosity systems (viscosity is about several hundred thousand centipoises), the viscosity can even be reduced to 1/10-1/20 of the blank. |
Anti-settling Dispersant | YRFC-12 | Yellowish Paste | Oil-based | Efficient anti settling and anti hardening agent, featuring leveling, and viscosity reduction capabilities. It can solve the problem of coarse particles and low mesh fillers being prone to settling and hardening at the bottom of the barrel. |
Wetting dispersant | YRFC-11W | Brown clear liquid | Water-based | Only a small amount of YRFC-11W can enhance the wetting of powders and base materials, and effectively reduce the adsorption between powder particles, so as to achieve wetting, leveling, dispersion and other apparent effects. |
