Where Can You Use Epoxy Powder Coating?
Due to its resistance to corrosion and harsh chemical, epoxy powder coating is used as a metal protector for a wide variety of applications:
- It coats pipelines, pillars and poles
- Epoxy powders protect steel rebars in high load bearing structures
- Its anti-corrosion properties work for marine structures and vessels
- Epoxy powder coating protects industrial furniture, for when it is exposed to aggressive cooling, and cleaning and lubrication fluids
- Epoxy powder coating is applied to household goods such as washing machines, refrigerators, microwaves and stoves.
How Do You Apply Epoxy Powder Coating?
As with other powder coatings, the usual way to apply epoxy powder coating is with an electrostatically-charged spray gun.
The gun charges the powder as it passes through the spray head, creating an opposite charge to the substrate of the part being sprayed. This makes the powder adhere to it.
You then bake the sprayed part in an oven. Powder coating melts at temperatures between 140°C and 220°C. This starts a curing process as the reactive components in the powder melt and flow together.
Once the powder coating has melted, fused, cooled then hardened, it leaves a tough, uniform film on the substrate it has coated.
Environmentally Friendly Coatings
Epoxy powder coatings are non-hazardous and easy to both transport and dispose of without causing environmental damage.
They are also highly economical with waste, since any powder you overspray you can recover and re-use.
Advise
The surface should be cleaned properly from oil, grease or any type of rust.
Curing Temperature
The curing schedule is 10-15 minutes @180- 200ºC metal temperature.
Handling and Storage
Store in a cool and dry place at a temperature lower than 30°C. Higher temperature may damage the chemical and mechanical properties of the powder
Application
This chemistry of powder coating finds its applications where maximum corrosion and chemical resistance is required. These are ideal for indoor applications and away from direct sunlight. The coating is smooth.
It is always recommended to use a top coat with transparent powders on the top of the metallic powders. The top coat prevents oxidation of the metallic pigments of the base coat thus enhancing the life of the coating.
Automotive components, metal cabinets, tool boxes, bathroom fittings, power tools, wire goods, electrical enclosures, hospital equipment, office furniture, oil filters, shelving, Safety equipment’s, coatings for pipes, ceiling panels, hardware fixtures, fire extinguishers, sports and recreation equipment, hand and power tools, brass plumbing and hardware fixtures, tool boxes, fire extinguishers, safety equipment, appliances etc
