We understand that what you are looking for in a product is better quality, durability, superior performance, corrosion resistance and aesthetic excellence. That is why we have designed our finishing process to excel in all those aspects. For close to 10 years, we have consistently been providing coatings of such high quality that are also better for the environment.
Advice & Guidance
- Increase voltage, fluidization and powder feed.
- Check resistance between different objects on conveyer. The ideal film reading is 0 ohm.
- Check earth connection from conveyer and outward.
- Check spray equipment fuses, voltage, electrodes in gun mouth and all electrical connections to high tension cable.
- Check powder by using another powder spray gun.
- Adjust spray gun equipment parameters for uniform powder output and recommended film thickness.
- Use fastest possible heat up rate in oven.
- Check optimum distance between object and gun mouth.
- Different hose lengths between powder feeds and guns
- Air pressure too low
- Electric fault or partial blocking of injector hose or gun
- If problems arise due to over or under-curing from oven
- Check that all thermostats are working properly
- Check air circulation
- Check metal temperature using temperature recorder.
Why Powder Coating?
Typically applied to metal products by electrostatic spray, the coated item is then heated and the powder melts into a smooth, continuous and encapsulating film. When thermosetting resins are used, the coating changes chemically (crosslinking) during cure, resulting in a decorative / functional finish with superior performance characteristics.
- VOC emissions reduced to near zero.
- No sludge or solvent disposal.
- Virtually 100% material usage, over spray can be reclaimed.
- Reduced health, fire, safety hazards.
- One step compliance, virtually 100% solids.
- Significant reduction in disposal costs.
- Typically lower applied material costs.
- Cleaner plant operations, reduced costs.
There are two basic classifications of powder coating materials. They are "thermoplastic" and "thermoset" powders.THERMOPLASTIC POWDERS
Thermoplastic powders are generally applied to a surface that has been pre-heated to a temperature significantly higher than the melting point of the powder. It melts and flows when heat is applied but continues to have the same chemical composition when it solidifies on cooling. Nylon powder coating materials are the most commonly used thermoplastic powders. Thermoplastic coatings are known for their wear and chemical resistance.THERMOSET POWDERS
Thermoset powders are 100% solvent-less and are generally applied by means of electrostatic spray equipment that provides each powder particle with a small electric charge, which in turn sticks to the earthed substrate. Thermoset powder coating systems offer broad formulation flexibility. They are very durable and are widely used.
