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).
