High adhesion powder coating uses specialised polyester resins and high-performance cross-linking polymers (sometimes with TGIC) to bond strongly to metal — often with little or no primer — and electrostatically wrap into deep recesses and angles. It gives uniform coverage, corrosion resistance and durability on complex, hard-to-coat parts.

Key Characteristics

No / Minimal PrimerBonds directly to the substrate, simplifying the line.Excellent UniformityElectrostatic wrap penetrates recesses for even film.

Corrosion BarrierAdvanced formulation plus pretreatment resists corrosion even if damaged.Durable & WeatherableGood UV resistance for harsh outdoor conditions.

Applications & Use Cases

How to Achieve High Adhesion

1. Surface preparation. Pretreat the metal with a conversion coating — iron or zinc phosphate (or chromate on aluminium) — to create a uniform, inert surface.
2. Select the right coating. Use a high-transfer-efficiency (HTE) or high-performance polyester-based coating with the matching cross-linking polymer.
3. Apply correctly. Electrostatic spray lets the powder wrap around complex shapes.
4. Cure appropriately. Heat in the oven so the powder melts, flows into a continuous layer and cross-links into a hard, durable film.
