1. Catalysts mainly used in the production of polyester resins for powder coatings
2. Catalyst, can be used for the synthesis of saturated polyester powder coatings and coil coatings;
3. It can be used in the production of gel coatings, sheet molding compounds and unsaturated polyesters in casting applications; the catalyst can be used in the production of polymeric plasticizers.

 

 

 

 

 

 

 

 

 

 

 

 

Anti-foaming agent mainly inhibits the formation of bubbles, avoiding affecting the dispersion and grinding efficiency and the accuracy and efficiency of canning measurement. Anti-settling and thixotropic agents are added at this stage, mainly because most anti-settling and anti-sagging additives need to be combined with pigments and fillers. Co-grinding and fully adsorbing, the effect will be significant. Functional powdery additives, such as rust inhibitors, corrosion inhibitors, flame retardants, etc., need to be dispersed to the required fineness, so people are added to grind during the grinding stage.

Coating production preparation process
Add additives
Preparation of paint metal pigment paste (aluminum paste, pearl powder, etc.)
Wetting and dispersing agent, anti-settling agent, thixotropic agent
Wetting and dispersing agents mainly help the wetting and dispersing of metallic pigments. The sedimentation aid and thixotropic agent need to be added at this stage or need to be made into a pre-dispersed slurry and then added at this stage, mainly because most of the anti-settling, anti-sagging, and metal orientation additives can prevent these dense metal pigments from being produced, Formation of sedimentation during storage
Matte coating matting powder, wax powder, wax slurry dispersion
Wetting and dispersing agent, anti-settling, thixotropic agent

Wetting and dispersing agents mainly help the wetting and dispersing of matting powder and wax powder, and at the same time can help prevent the sedimentation of matting powder. The main function of anti-settling and thixotropic agent is to prevent the formation of hard deposits and help the preparation of auxiliary paint, metallic paint and varnish for matting powder.

Defoamer, anti-shrinkage, leveling agent, smoothing agent, urging to adjust the finished agent in the back of the coating, curing accelerator, adhesion paint: color paint, primer, matte accelerator. Anti-skinning agent, conductive, Anti-static, hammer grain additives, flame retardants, plasticizers, ultraviolet absorbers, light stabilizers, anti-corrosion agents, etc.
