Why Powder Coat with ADA Powder Coating?

 

What is Powder Coating?

The powder coating process uses a solvent free dry mix of plastic resins, pigments and fillers that melt and fuse together when heated. The solid particles of coating are electrostatically charged in a spray gun and carried by low velocity air to the surface of the piece to be coated. The electrostatic charge holds the powder particles in place while the part is cured in an oven. The heat of the oven causes a chemical reaction to occur and the powder to cure, creating a highly durable finish.

 

Is it Environmentally Friendly?

Powder coating is an environmentally friendly process unlike solvent based wet paint systems. With EPA regulations growing ever stricter, powder coating is fast becoming the technology of choice. Since the powder coating process does not use solvents in any way, VOC emission problems are eliminated.

Durability

Powder Coatings resist cracking and peeling and are extremely abrasion corrosion and chemical resistant, but is not a rust inhibitor. The performance characteristics of powder coating match or exceed the characteristics achieved from conventional solvent based coatings.

 

Colours

Powder coatings are available in a large variety of stock colours, metallics, textures and special effects. Made to Order colours require a lead time of 6 weeks and have a minimum quantity of 60 kgs.

 

What can be coated?

 

Any ferrous or non ferrous object that can hold an electrostatic charge and withstand the heat of the curing process can be powder coated. Powder can be applied to intricate surfaces and still maintain a uniform finish across the entire piece. Powder coating is ideal for items such as:

• Industrial Fabrications
• Architectural Signage
• Trade Show Exhibits
• Metal Fencing & Railings
• Retail Displays & Fixtures
• Garden Furniture
• Motorcycle Frames, Wheels & Parts
• Automotive Frames, Wheels & Parts
• Off Road Vehicle Parts
• Push Bike Frames & Forks
• Cast Iron Beds, Chairs, Verandah Lacework
• Wrought Iron Fencing & Gates

 

High temperature masking tape can be applied to special surfaces such as thread or high tolerance areas to keep them from being coated. We also use high temperature silicon plus for threaded holes or shafts.

 

The high oven temperature makes the use of plastic and resin body fillers a problem. Often the powder will not bind to a fillers surface causing bubbles in the coating. To be safe, fill any depressions with a torch using brass or welding rod as fill.

 

Clear powder coating serves the same purpose as clear coat wet paint. It protects the underlying finish and adds depth and lustre to the surface. Clear powder coat is applied as a second coat. Then the piece is returned to the oven for a second curing process. Use clear powder coating on ay piece that exposure to elements could cause it to fade or be subject to damage.

 

At ADA Powder Coating we strive for the best finish possible and the best finish starts with the best surface preparation. We have our own in house abrasive blasting facility. Abrasive Blasting our own items and not farming them out to other contractors, lets us be in control of the entire powder coating process from start to finish.

 

Powder coatings rely on a clean, pre-treated surface like any and every other coating. Rusty metal deposits must be removed prior to powder coating, as over coating with powder will only mask what is fundamentally corroding metal. Blasting the surface of your material prior to coating provides an excellent surface for the powder coating to adhere to. Blasting also increases the adhesion and durability of the finished product. Our blast system uses garnet and/or glass media to remove the old finish, metal oxides or manufacturing by products that remain on the metal.
