DESCRIPTION

Highway guardrail powder coating provides a more durable and cost-effective alternative to traditional liquid paint. In fact, we've been offering high quality industrial powder coating solutions for all types of applications for more than 20 years. Guide rails take a beating over time. With the use of super durable powder coating materials like TGIC Polyester, you can be sure your guide rails will be able to withstand the harsh climate for many years to come. The lower lifecycle costs and lack of maintenance requirements means highway guardrail powder coating can give you an excellent return on your investment. And because our highway guardrail powder coating is applied as a dry powder without the use of chemical solvents, you have the peace of mind that comes with knowing you are implementing an environmentally friendly process as part of your operation.

 

Highway guardrail powder coating is applied over the surface of the metal in a uniform pattern; in order for the particles to adhere to the material, they must first pass through a charging field supplied by the delivery system.  The charged particles are then attracted to the grounded metal via a clamp.  The powder is attracted to microscopic "ridges" in the grain boundaries, and settles in between these ridges. Once the powder has been applied to the enclosure, we place the coated enclosure in our oven and allow it to melt. Once the particles begin to melt, they flow out and chemically react to form a higher molecular weight polymer in a network-like structure.  This curing process, called cross-linking, requires a certain degree of temperature and a certain length of time in order to reach full cure and establish the desired film properties the powder was designed for.
