The recommended use concentration is 0.4~0.6%, and the specific use amount will depend on the actual situation. The product is unstable under alkaline condition and easy to decompose, so it is recommended to use in the system with pH less than 9. It is recommended to add it to the product in a later production process and disperse it well.
Add modified polysiloxane with wetting and matting powder arrangement
Comparison of the effect of adding modified polysiloxane on the wetting and alignment of matte coating powder
Wax powder, wax slurry
There are many types of waxes, including natural animal beeswax, shellac wax, mineral Montan wax, vegetable palm wax, petroleum wax, micro wax, and various synthetic waxes, such as polyethylene wax, polypropylene wax, poly Amide wax, polytetrafluoroethylene wax, Fischer-Tropsch wax and mixed waxes, etc. Its supply forms are micro powder, emulsified, dispersed and paste. Regardless of the type of supply, flocculation, stratification, sedimentation and unevenness may occur. Therefore, in order to give full play to the characteristics of wax and obtain the best effect, it is best to go through high-speed dispersion to ensure uniform dispersion in the coating and to be dispersed to the required fineness. Among them, the effect of high-speed dispersion depends on the viscosity, concentration, shear force and dispersion time of the dispersion. Generally, fineness scraper can be used to check the fineness. The specific choice of wax depends on the desired effect and improvement. Performance and undesirable side effects, and the properties to be improved include: scratch resistance, abrasion resistance, slip, anti-fitting, abrasion aid, matting and special hand feeling, etc., which can be selected according to the required characteristics and side effects to be avoided Variety and supply of wax.
Modulation of finished paint after coating
Additives added in the stage of preparing finished paint (color paint, primer, matt paint, metallic paint and varnish) mainly depend on: paint formulation design tasks and characteristics, paint performance and quality requirements, coating methods and baking conditions , Coating function and applicability, etc.
