Description: FS-161 is a polymer dispersant containing multiple anchoring groups. It has a good wetting and dispersing ability for various organic pigments, which can greatly reduce the operating viscosity of the grinding system and increase the pigment filling amount. The strong anti-flocculation and coarsening ability can greatly improve the storage stability of the grinded color paste, and the color paste of the ground single color is not easy to float.
Physical and chemical parameters:
| Composition: | high molecular weight polyurethane block copolymer containing pigment affinity groups |
| Appearance: | yellow transparent solution |
| Active ingredient: | 30% |
| solvent: propylene glycol methyl ether acetate: butyl acetate | 6:1 |
Features:
◆ FS-161 is suitable for medium and high polarity systems, has good matching with commonly used coating resins, and has good versatility in coating systems.
◆ FS-161 can significantly improve the wetting and dispersing ability of the base material to the pigment and filler, reduce the system viscosity, improve the fluidity, and shorten the grinding and dispersion time.
◆ FS-161 is a polymer-based dispersant, which has an excellent ability to prevent coarsening. Compared with the small-molecule wetting and dispersing agent, it can greatly extend the storage stability of the ground color paste.
Application system and dosage: suitable for medium and high polarity systems, the dosage is different according to different usage systems, for inorganic pigments 10%-15%, titanium dioxide 5-6%, for organic pigments 30%-50%, carbon black 70%-100% (depending on the specific surface area of the pigment).
Packing: 25kg iron drum
