Product Overview

S-200 is a nano-grade fumed alumina C that can improve the flowability of powders, enhance the positive charge of friction-type powders, and improve the coating performance of powder coatings applied by electrostatic friction. AEROXIDE Alu C fumed alumina is a nano-scale alumina micropowder produced using a process similar to AEROSIL fumed silica. It can improve the flowability and storage stability of powder coatings. Because it carries a positive charge, it is particularly effective in increasing the powder rate of powder coatings.

Technical Parameters

Product Features

• Improves flowability and increases powder rate. 
• Enhances the storage stability of powder coatings. 
• Increases the uniformity of powder charge and the spray area. 
• Does not adversely affect the leveling and gloss of powder coatings during curing within the recommended dosage range.

Usage and Dosage

This product can be directly added to finished powder after sieving with 80 mesh or higher, or it can be added during chip crushing. The dosage is 0.1~0.3% of the total formula.

Application of AEROXIDE Alu C Fumed Alumina in Powder Coatings

Whether the powder coating is positively or negatively charged, its electrostatic charge will not be adversely affected. The commonly used dosage is less than 0.3%, which does not adversely affect the leveling of the powder coating during the curing process. Alumina C has a very strong positive charge tendency. Therefore, Aeroxide Alu C (alumina C) is used in friction-applied powder coatings, not only to increase the positive charge of the powder coating in use, thereby providing deposition or coating efficiency, but also to reduce the formation of static electricity in the final powder coating, which adversely affects the overall flow performance of the coating

Note

• Over-addition may slightly affect the color in dark colors such as black and bright colors.
• Unused packages must be sealed to prevent moisture absorption.
