Reactive Coatings

Powder, Epoxy and other Protective Coatings

As a provider of powder coating services, people can see my opinion on the answer to that question as being partial. However, try to describe as little partisanship as possible the advantages and disadvantages of powder coating and anodizing.

Advantages of Powder Coating

One of the major advantages of powder coating is to reduce pollution air compared to liquid coatings. When the powders are cured in an oven that does not emit volatile organic compounds. There are also options in terms finishes as fine textured, peeling, matte, semi-gloss, high gloss, etc.

Anodizing with lots of different colors are created and then running through color. If parts must be reworked or more parts are added to an order, a new batch should be done. This can be very expensive and there is a good chance that there will problems with consistency from one batch to another. The advantage of powder coating is that consistency is easier to achieve by the supplier of dust, so the painted parts This week and next week goes by with little difference in the end. The advantage of powder coatings is that consistency is closely monitored so that each lot is assessed with teams of color, visual inspections, mechanical and chemical tests. This ensures that each lot is within a tight tolerance of the original rule in the file. This prevents the "drift" over time and helps ensure uniformity of each batch.

It is also relatively easy for most machines powder paint now to change from one color to another so that the cost is quite small.

The number of colors available is incredible. Powder Supplier of laboratories have in the house, where they can match the colors of powder coating of liquid paint or any other color, just to have a color swatch to match. And can be made as small as a box (25 barrels) of powder at once.

Depending on the ultimate use of the product, anodizing can be fragile and therefore, is the metal will be bent after anodizing or is subject to drastic changes in temperature, can strip the anodized finish.

Advantages of Anodizing

Anodising finish is harder target = "_blank" title = "Powder Coating Toronto"> powder coating. Anodizing tends to be better able to withstand the abuse of powder coating as well. You can also have a better UV protection, while powder paint if you want the same level of protection you need to use a super durable powder. This depends, however, the type of anodizing being used. Anodizing is not organic color retention of the powder coating, anodising but usually has better colorfastness inorganic powder paint.

The anodized finish, some would say which is generally more metallic with a portion of powder-coated. Some powders have been developed to mimic anodized, but there is a difference. An anode layer unlike paint actually bonds and chemically alters the aluminum surface, becoming part of it in oxide form. The painting, as located on the top surface of the bonds, but never actually becomes part of the metal matrix. As a result of anodizing does not peel, but can break during flexion, because the part that is bent or stretched or compressed beyond the limits of the surface tension of the anode layer.

In Overall, the comparison of prices may vary depending on the color and size you are looking at implementation. The only way to judge the most cost effective way to go would get the parts to be noted in different finishes and lot sizes equal to be sure.
