Powder coatings are generally a one-coat finish, applied to a properly cleaned and pretreated substrate. Prior to spraying, the powder coating material is generally sieved and then fluidized for 10 minutes to condition it. Powder coatings are a factory applied finish using specialized equipment. The equipment consists of electrostatic spray guns (manual or automatic), a powder spray booth, and an oven to bake (or cure) the coating.

Unfortunately there is a myth that since powder coating is so much easier to apply than wet paints, and retains a very hard film, that powder coatings can withstand anything and everything. Indeed this carefree view has led to some disappointing applications of powder coatings. Powder coatings rely on a clean, pretreated surface like any and every other coating.

Powder Coatings are a factory applied finish using specialised equipment. The equipment includes an electrostatic spray gun, spray booth and an oven to bake (or cure) the coating. On site application is not possible given the hot curing cycle required to fuse the coating.

New powder coating technology has been developed by Dulux to powder coat engineered timber products like MDF board. Known as Dulux Trimatrx®, this unique powder coating is available only through Dulux Registered Applicators for Heat Sensitive Substrates. Dulux have tested many grades of MDF board with Dulux Trimatrx® and most boards provide a good surface for coating. For outstanding results, Dulux recommend Trimatrx® MDF Board in conjunction with the Trimatrx® Powder Coat.

Whilst powder coatings generally require no primers, it is important to provide a clean and pretreated surface for the powder coating to adhere to. Metals that are planned for internal location can escape the need for pretreatment, however it is advisable to provide some metal pretreatment such as a phosphate finish to steel or chromate finish to aluminium to ensure maximum performance of the finish.

While powder coatings normally require no primers, it is important to provide a clean and properly pretreated surface for the powder coating to adhere. For steel substrates, it is advisable to abrasively blast clean prior to coating and applying an iron or zinc phosphate pretreatment. For aluminum substrates, it is advisable to provide a chromate or chrome-free conversion coating to the aluminum surface. Chrome-free pretreatments are rapidly replacing hazardous chromate pretreatments.

Unfortunately, there is a myth that since powder coatings are so much easier to apply than liquid coatings, and offers a very hard film, they can withstand anything. This carefree approach has lead to some disappointing applications and negativity in selecting powder coatings for premier architectural projects. Powder coatings rely on a clean and properly pretreated substrate. Oxidation deposits, which are corroded material, must be removed prior to applying the powder coating.

Approximately 100% more due to the cost of the active ingredient and the specialized method of incorporation, for which we hold a patent. Is there a feel due to Anitmicrobial Coatings which differs in texture from other powder coatings? I refer to "hand", in the textile industry sense. Generally, there is nothing in the feel or appearance of the coating that will indicate an antimicrobial product, but the incorporation process can lead to more orange peel.

Powder Coatings are produced by dry blending of resins, pigments, additives and curing agents, which are then extruded at elevated temperatures to melt mix the ingredients. The material then becomes thick and viscous like a honey mixture which is cooled using super chilled water, before the material is crushed progressively to a fine, well defined particle size.

Powder coatings contain no solvents, which simplifies their transportation and storage, but are classified as a nuisance dust. Workers should use proper dust masks, protective garments, gloves and skin creams to prevent inhalation or contact with their skin. Use mild soap and water to remove from skin contact. Since powder coatings contain no solvents, they do not release hazardous VOC's (volatile organic compounds) or HAP's (hazardous air pollutants) into the workplace or the environment.

Most powder coatings will tolerate temperatures up to about 500° F. There are a few powders that will go to 800° F. but they are limited to black. For temperatures above that we recommend Ceramic Coating. Our Cast Iron Gray and Polished CermaKrome are good for temperatures up to 1,300° F. and our Satin Black is good up to 1,700° F.

The coatings are applied in two parts: base and catalyst. They are best applied with high velocity low pressure ( HVLP) spray equipment. These coatings do not produce the best results when either “rolled” or “sprayed” on through conventional spray equipment.

They should be stored on end and in the dry. Underlayments should be applied to a smooth, dry roof deck, free of debris. Care should be taken not to damage the product with foot traffic once applied. Damaged product should be replaced before covering.

Australian Standard AS3754 "Safe application by electrostatic spray" outlines the procedures for safe application of powder coatings. Copies of this standard can be obtained from your local Standards Australia office.

Powder Coatings are not classified dangerous goods. There are no solvents in powder coatings which simplifies the transport and storage of powder coatings.

Everything is relative, and powder coatings are considered far more environmentally friendly than wet paints or anodising. Powder coatings use no solvents which are harmful to the environment. Oversprayed powder can be recovered, sieved and then reapplied to other products which helps reduce waste powder. Whilst some councils restrict the waste disposal sites for powder coatings, the products have limited to no leaching effect in dry form and no leaching effect in the cured form.

Powder coatings can be safely cleaned up via a brush and spade or a vacuum cleaner, provided the amount of powder is not excessive. For large spills, the powder should be shovelled into a plastic bag inside a carton, and tipped into the box for easy disposal.

The powder coating's storage life varies according to the resin technology and the storage conditions at the applicator. If the powder coating is stored under improper environmental conditions, the materials will absorb moisture and become lumpy. Follow the powder manufacturer's recommendations for storage conditions and always re-test stored powder to confirm no degradation in film properties.

The only similarity is that they are both baked-on finishes. Powder coatings are baked at 425 degrees to melt the powder to a smooth finish. You must never get it that hot again, or it will burn off. Powder coating is basically very tough paint that is available in almost any color. Ceramic thermal barrier coatings were developed by NASA and the aerospace industry thirty years ago, for thermal insulation on rocket and jet engines.
