BYK Powder Coating Process Additive (Appearance Enhancer)
BYK powder coating process additives contribute to labor-saving in the paint manufacturing process and are highly effective in improving appearance (haze, gloss, leveling) and degassing properties.
BYK powder coating process additives BYK-3950 P, BYK-3951 P, and BYK-3955 P contribute to labor-saving in the paint manufacturing process and are very effective in improving appearance (haze, gloss, leveling) and enhancing degassing properties. Expected effects from the application of process additives: - High concentration of pigments and fillers - Improved appearance (haze, gloss, leveling) - Reduced melt viscosity during curing - Simplification of the extruder process - Enhanced degassing properties For improving degassing properties in primid-based powder coatings, we recommend wax additives CERAFLOUR 960 and CERAFLOUR 964. - CERAFLOUR 964 enhances degassing properties without adversely affecting gloss (non-blooming). It is very suitable for glossy powder coatings and is particularly ideal for dark-colored applications where visible surface defects are likely to occur. Its low melting point also makes it optimal for low-temperature curing systems (LT systems).
basic information
【Additives for Powder Coatings】 BYK-3950 P: General-purpose grade, effective for all resin types. Melting point 86°C. BYK-3951 P: Effective for inorganic pigments/fillers such as titanium dioxide. Reduces melt viscosity during curing. BYK-3955 P: Improves color acceptance and leveling of carbon black. 【Wax Additives for Powder Coatings】 CERAFLOUR 960: Standard type. Improves wetting and leveling of pigments. Melting point: 145°C, average particle size (D50): 4μm. CERAFLOUR 964: For low-temperature curing systems, rapidly effective due to low melting point during extrusion and curing. No blooming effects. Melting point: 75°C, average particle size (D50): 20μm.
