In the consumer electronics sector, the coating of device casings directly impacts aesthetics and durability. Chemi Tech wax powder, as a high-performance additive, optimizes coating performance through the following core functions:
Enhanced Surface Smoothness and Scratch Resistance
Wax powder migrates to the coating surface during curing, forming a uniform protective layer. For example, adding 0.5%-3% polyethylene (PE) wax significantly increases coating hardness, effectively resisting scratches from keys, coins, and other hard objects. Polytetrafluoroethylene (PTFE) wax at 0.1%-1% provides superior smoothness for premium electronic housings.
Optimized Hydrophobicity and Anti-Fouling Properties
The hydrophobic nature of wax powder constructs a micron-level barrier on the coating surface, blocking moisture penetration and protecting internal components. Simultaneously, its low surface energy prevents oil and dirt adhesion, simplifying cleaning.
Improved Processing and Coating Uniformity
Incorporating 0.2%-0.5% wax powder enhances powder flowability during spraying, reducing clumping and orange peel effects. Micronized wax (3-10μm particles) ensures even dispersion within the resin system, avoiding surface pits or gloss inconsistency.
Chemi Tech offers customized wax solutions for substrates like aluminum alloys and engineering plastics, balancing cost and performance for long-lasting protection in smartphones, laptops, and other electronic devices.
