Industrial powder coatings use either thermoplastic or thermosetting techniques during the manufacturing process. While thermoset coatings have their advantages, there are times when a thermoplastic option will meet more of your coating needs.
What are the benefits of choosing thermoplastic coatings?
1. More Flexible Coverage
Thermoset coatings don't suit all applications. These coatings are typically used on items that only need a thin or standard coating.
If your products or items need a thicker coating, then a thermoplastic powder is worth considering. You can increase the depth of the coating in a single application so you get a seamless finish without needing to use multiple coats. Plus, you can choose from a variety of coating types from hard shells to softer rubber-like materials, depending on your needs and preference.
2. Increased Protection
While thermoset coatings are strong and resilient, their application method doesn't always give complete coverage. A coating that looks intact and sealed may actually contain minute holes.
As the coating ages, these holes can let in air and moisture. These breaches can corrode the coating and the item it covers.
Thermoplastic powder coatings are stronger and more robust in certain conditions. They give a better level of protection with a more complete seal. This reduces the chances of damage or wear as time passes because they aren't porous in the same way.
Also, thermoplastics are more weather-resistant, making them a good option for use outdoors or in certain environmental conditions. They can hold their own in rain, sunshine and even in a salt environment, for example.
This resistance increases the longevity of the coating. If the coating lasts longer, then the item it covers remains protected for longer.
3. Repair Options
A thermoset coating sets using a chemical reaction. Once the coating is on and cured, it can't change. If it has damage or wear, you'll generally need to replace it if it can't be patched up.
Thermoplastics set hard; however, they retain the ability to change. If you expose them to the right amount of heat, for example, then they melt back down. So, if a coating breaks or gets a hole in it, it might be repairable. If you heat it, it will melt and recover the damaged area.
