Epoxy powder coating as a primer

No need to prepare the surface before spraying ― a harmful myth. Many doors, bicycles and handrails were damaged as a result. Even more craftsmen have lost the trust of customers and orders.

Read our article today and avoid unnecessary hassles.

Why do you need a primer?

To prevent cracks, chips and other troubles on the painted surface, it should be homogeneous, without oxide, before painting. To do this, clean it with sand, wash it, cover it with additional layer of paint ― primer.

It won’t be excessive on complex, uneven structures that are difficult to paint. For example, you can align a welding seam in such a way. At bends, corners, recesses powder could be applied thinner or thicker, which is harmful to the coat. There is a risk of rapid corrosion.

Why is it suitable for primer?

Because it protects well against rust and chemicals. Some epoxy resins have a low molecular weight, creating a strong film with a thickness of only 30-40 mm. Therefore, it is not noticeable at all, and protection is much higher. These polymers have excellent adhesion ― that is, they adhere well to the surface.

The paint is resistant to hits, abrasion, scratches, but has one drawback ― poorly withstands various weather conditions. Temperature fluctuations, rains, especially sunlight ― detrimental to it. But with a “friend”, resistant to weather, it forms a very reliable coating. Polyester paint can play a role of such “friend”. However, this upper layer depends on many factors. Epoxy powder can be applied once more to equipment operating in acidic or alkaline environments.
