In the evolving world of industrial surface finishing, Powder Coating stands out as a revolutionary solution for durability, sustainability and aesthetics. At Intech Surface Coating, we combine 30+ years of experience, advanced equipment and stage pretreatment process to deliver long-lasting results across industries like automotive, agriculture, furniture, and heavy equipment.
What Is Powder Coating?
Powder coating is a dry finishing process where finely ground particles of pigment and resin are electrostatically charged and sprayed onto metal surfaces. After application, the part is heated in a curing oven, allowing the powder to flow and fuse into a smooth, durable finish.
An electrostatic charge attracts powder particles to a grounded metal surface. The part is then cured in an oven, fusing the particles into a smooth, tough coating.
What Is Powder Coating Made Of?
- Resins: The backbone (polyester, epoxy, or hybrids)
- Pigments: Add vibrant, long-lasting color
- Curing Agents: Enable cross-linking during heat treatment
- Additives: Improve flow, UV resistance, texture
Types of Powder Coatings
1. Thermoset Coatings
- Undergo permanent chemical changes upon curing
- High resistance to heat, chemicals, and scratches
- Ideal for: Outdoor structures, auto parts, tools
2. Thermoplastic Coatings
- Melt and re-solidify without chemical transformation
- More flexible, but lower heat resistance
- Ideal for: Appliances, furniture, wires, playground equipment
Intech Tip: Choose thermoset for UV exposure and thermoplastic for impact resistance.
How the Powder Coating Process Works
Here’s a simplified overview of how we deliver a superior powder-coated finish at Intech:
1. Surface Preparation
Blasting: Removes rust, scale, or old coatings.
Chemical Pretreatment: Our 8-stage pre-treatment ensures surface cleanliness and promotes adhesion. It includes:
- Alkaline cleaning
- Iron phosphate treatment
- RO rinse
- Zirconium coating for corrosion resistance
2. Masking
We protect non-coated areas using high-temperature masking materials for precision coating.
3. Powder Application
Using electrostatic spray guns, we coat the metal parts with finely charged powder.
4. Curing
Heated in an oven (usually 180–200°C) to melt and fuse the powder into a uniform, durable coating.
Powder Coating Applications
Powder coating is trusted in sectors that demand durability, aesthetics, and cost-efficiency, such as:
- Automotive: Rims, bumpers, chassis parts
- Industrial Machinery: Fabricated metal, compressors, panels
- Consumer Goods: Appliances, furniture, lighting
- Construction: Fencing, railings, architectural panels
