Zinc enriched primer is one part of a two step coating system. The Zinc Enriched primer is exactly what it sounds like. It is a zinc rich primer that is designed to offer very good corrosion resistance. The second part of the coating system would be the finish coat that is applied to achieve the desired finish appearance. The zinc primer coating system is designed for superior corrosion protection of steel.
We have spent some time researching different coating options. We have had our products salt spray tested with different coating systems and the results speak for themselves with this 2 Stage Zinc Enriched Coating.
Salt spray testing is a standardized method of testing corrosion resistance of coated and non-coated surfaces. Salt spray testing is an accelerated corrosion test that produces a corrosive attack on the samples in order to predict its suitability in use as a protective finish. The appearance of corrosion produced is evaluated after a period of time. Test duration depends on the corrosion resistance of the coating; the more corrosion resistant the coating is, the longer the period required within testing without showing signs of corrosion. Salt spray testing is popular standardized and reasonably repeatable. Corrosion is a very complicated process and can be influenced by many external factors. Nevertheless, salt spray test is widely used in the industrial sector for the evaluation of corrosion resistance of finished surfaces or parts.
Powder coating is a very durable finished widely used throughout the industry, however, many factors affect its durability and lifespan in the end. Remember, if any metal part has a small rock chip, scratch, or blemish simply touch that spot up because that one spot will eventually become a rust spot. Once a rust spot forms it will spread from the inside out. A small rock chip may appear to be only a small rust spot but in reality it may be a fairly large spot masked by the finished coating of the product. Naturally the products we produce are built to be abused and will endure any punishment thrown at them. With that being said the finished will get damaged when it is smashed against rocks and other trail obstacles. If the surface finish of anything steel is damaged, that area will need attention before it begins to rust. Take the time to care for your product just as you would the paint on your vehicle. Touch any damaged spot up with paint or truck bed coating to prevent rusting issues. The finish of your product will be greatly affected by the environment. If the part is exposed to salt or other road-use chemicals the lifespan of the finish will be affected especially if there are any existing chips, scratches or scrapes.
