Powder coating involves spraying a fine, electro-statically charged powder onto a pre-treated metal surface. The coated surface is then baked in an oven to fuse and cure the powder into a smooth polyester finish that's hard wearing and extremely resistant to chipping, scratching and fading.
Our 6m x 2m x 2m oven (basically the size of a 20ft shipping container) can powder coat anything we can fit in it. We're able to handle long and short runs with ease.
Powder coating is a robust, more efficient, cost-efficient and greener choice than spray painting. The result is an attractive appearance and finish that is the perfect solution to preserve and extend the life of items made from metal that spend their life either indoors or outdoors such as:
At Pacific Powder Coating we have over 200 colours to choose from with many different finishes including metallic, satin, matte, gloss and textures. Modern powder coating technology means powder coated colours stay bright and vibrant for extended periods of time. Check out the range of Interpon and Dulux Powder Coatings here.
Generally, powder coated outdoor items should be maintained every six months. Where pollutants are more prevalent, such as salt-spray, geothermal or airborne industrial waste, clean every three months. Direct sunlight, dirt and grime also build up and should be cleaned off regularly.
Clean powder coated surfaces with a soft sponge or brush, fresh water or a mild detergent, then rinse and dry gently. Avoid harsh solvents but methylated spirits, ethyl alcohol or isopropyl alcohol can be used in small amounts. Clean off paint or stain splashes or sealants immediately.
Pre-treatment is key in the powder coating process to ensure a long-lasting result. Correct preparation methods vary so we apply different techniques for pre-treating substrates before we apply their powder coated finish. Our quality pre-treatments include water or chemical washes, sand blasting, acid de-rusting and solvent cleaning.
Either in-house or sub-contracted, we clean products to remove oil, grease, rust, dirt or other surface damage sometimes not visible to the naked eye. Items or substrates are then hung on an overhead conveyor belt system and run through drying units. This pre-treatment process enhances surface condition and improves adhesion of the powder coat.
Pacific Powder Coating has extensive on-site pre-treatment facilities suitable to process a range of metals in sheet, extruded, fully manufactured forms and smaller intricate parts and shapes. Large frames and product forms are accommodated using a recommended spray poly-etching process suitable for most metal products.
Powder coating involves grounding the metal substrate before spraying electrically charged, flour-like coloured powder onto its surface in precise thicknesses.
Once items have been sprayed with the electrostatic charged powder, they're baked in large ovens at over 200°C to fuse the powder to the metal. This stage bonds, cures and seals the powder to the metal to form a polyester coat. The result is a hard finish that's tougher than paint and more resistant to fading and chipping.
