Specific Purpose Agent

Active Coupling Agent

Chemical Composition: Compound of multi-hydroxy higherfattyacid and ester .

Active coupling agent is organic compound, effective chelant, containing abundant hydroxyl, carboxyl, amine group, and other active groups. It is special for specific type of surface modifier, which is the very cost effective rheological additive.

Technical Specification:

 

content	Active coupling agent
appearance	Almost white or white fine powder
Melting range	95~110℃
relative density	0.96~1.05
Acid value	≤4
Activity	≥99
Volatile Matter	≤0.5%

 

Usage:

1. Provide active component, accelerate chelating for pigments and fillers, increase dispersiveness of pigment and fillers. Reduce dosage of resin, pigment and metal powder.

2. Accelerate the flowing, increasing the surface’s luster and richness of coating surface

3. Eliminate the crater and pinhole caused by materials’ inter-compatibility, resins’ unevenly distribution, or poor dispersion by extruder screw

4. good weathering resistance, that is good for increasing the coating surface’s saltfog resistance and water resistance.

5. Increase coverage of powder, raise anti-static property

6. Reduce dosage of matting agent, leveling agent, gloss enhancing agent, benzoin and other additives by 10%-20%, no need to add antistatic agent, lubricant or other modifier agent for coating surface.
