Corrosion Protection

For corrosion resistant coatings, the DECC Company utilizes both barrier and sacrificial types of engineered coatings which fuse to the metal substrate in order to provide added protection against salt, chemical, and high temperature corrosive environments. 

Barrier coatings provide a consistent film that prevents external elements from penetrating to the substrate. In other words, a barrier coating utilizes a thin layer of plastic resin which acts as a shield that blocks external factors from causing harm to the part. Every barrier coating contains a plastic resin protection layer which then combines with a filler layer to solve a specific problem. Wall paint, for instance, uses a coloring additive mixed with plastic resin and would be considered a barrier coating as it provides protection for the drywall while providing cosmetic appeal.

Sacrificial coatings contain certain elements, such as aluminum or zinc, which oxidize sacrificially to ensure that the substrate remains corrosion free. The salt spray resistant coatings, some which meet up to 1000+ hours of resistance, can also prevent galvanic corrosion when dissimilar metals are in contact with each other. Sacrificial coatings essentially fool the rust into eating away at the coating instead of the metal layers beneath. This happens because aluminum, or in some cases zinc, is added to the epoxy resin during the coating's manufacturing process.

Benefits of applying corrosion protection coating

• Improves functionality with a longer part life cycle.
• Increases fuel economy when applied to certain automotive parts.
• Lubricates parts which reduces load caused by friction.
• Lowers cost of servicing requirements as parts last longer.
• Resists harsh chemicals and extreme temperatures.
