Do you know what rebar is? It's actually ribbed steel bars that are then added to the footers and concrete walls. They have high tolerance to corrosion, so you're assured that the construction materials in your home don't easily break. Rebar can also extend life. Normally you have rebar powder coating, but with the introduction of polyester powder coating, we may see more improved rebar that is being sold in the market.

What is polyester powder coating?

There are more and more companies who are adapting powder coating as an alternative to paint, which actually takes a long time to dry, has tendency to chip, and can contain harmful and un-earth-friendly chemicals. They can also be utilized for rebar powder coating. One of the most efficient materials used in powder coating is polyester. It's usually a coating that is applied during normal temperature.

What are the advantages of using polyester coating in rebar?

When it comes to rebar coating, polyester may just prove to be more of a boon than a bane. Here are the many benefits businesses and even home owners can get out of it:

1. It dries up easily. The polyester coating is applied into the rebar for a thickness of up to 1,500 microns for every coat. These particles are charged electrostatically and, when heated, melt, which into powder that covers the entire material. It may seem to be a very long process, but in truth, a rebar powder coating using polyester may just take as fast as 30 seconds. The longest will be an hour.

2. It is definitely less expensive. Just because polyester powder coating seems to be a very new technology, it doesn't mean that it has to be very expensive. In fact, it is very cheap compared to using paints. This is because usually you have to apply two to three coats before you can get the right finish. With rebar powder coating with polyester, you don't have to. Once the polyester coating is sprayed into the rebar, both the chemical and the physical components of the particles will stick and be integrated into the material.

3. It increases the strength of the rebar. As mentioned, rebars is commonly used since they don't easily give in to corrosion. When you're going to use polyester coating, you are actually increasing their ability to do so, since polyester is a water-resistant material. Moreover, it is known to increase the mechanical strength of an object, including a rebar.

4. It has better ability to retain its physical characteristics. Paints tend to deteriorate over time, such as when they flake. Polyester powder coating doesn't. In fact, it is able to maintain its color and texture for a very long time, even if you're going to place it outside. A rebar powder coating such as this also guarantees excellent tolerance against resistance and change of color. This way, you don't have to constantly monitor the condition of your rebar. You can also look forward to lower repair and maintenance costs.
