Coil Coating Wax Additives for Long-Lasting Pre-Painted Steel Roofing

Pre-painted steel roofing requires coatings that resist mechanical damage, UV degradation, and environmental contamination. Wax additives provide essential protection and performance enhancement in coil coating formulations.

Challenges in Coil Coatings

• Abrasion and scratching during manufacturing, transport, and installation

• Gloss degradation due to prolonged UV exposure

• Surface contamination reducing aesthetic appeal

Wax Additive Benefits

1. Abrasion Resistance: Wax particles form a tough surface layer, resisting scratches and scuffs.

2. Gloss Retention: Some waxes help maintain surface shine by protecting pigments from UV damage.

3. Dirt and Water Repellency: Reduced surface energy helps prevent dirt accumulation and water staining.

Technical Application

Oxidized polyethylene wax is commonly used at 0.5-1.5% dosage levels in polyester or PVDF coil coatings for optimal balance of properties.

A roofing coil supplier observed 25% improved gloss retention after QUV weathering when incorporating oxidized PE wax into their coil coating system.
