Thermoplastic Powder coatings in detail

Thermoplastic powders consist of long-chain molecules, forming a type of coating that coats metals by melting at the desired temperature. This process exhibits mechanical and chemical strength upon cooling. These coatings excel in protecting metal structures against corrosion, wear, tear, and chemical attacks, outperforming other coatings. Notably, they offer extended lifetime, environmental impact reduction, and the ability to protect metal in temperatures as low as -70°C.

​

In industrial applications, it is common practice to coat all metal materials before usage for aesthetic, endurance, and safety reasons. The primary purpose of this coating method is to provide effective protection against corrosion. In contrast, other corrosion-preventing coatings like liquid, powder, PVC, or polyurethane generally exhibit lower performance and offer poor protection. Moreover, they release toxic smoke and solvent vapor into the environment during the production process.

​

Procoat Coating Services specialize in providing ideal solutions for protecting metals against corrosion, impulse, and chemical materials, particularly for thermoplastic powder coatings. The range of thermoplastic powder coatings available includes budget-friendly options based on polyethylene (PE) to high-quality polyamide (PA) and polyester powders, catering to diverse needs and preferences.

Features & Benefits
​

Thermoplastic powders are extremely adhesive to substrate and resistant to corrosion, scratch even impacts. Meanwhile, they are recyclable, that is to say, they can be remolded and reshaped to maximum cost efficiency.

Polyethylene Coating

Polyethylene was one of the first thermoplastics to be used for powder coating. This material provides a high degree of corrosive and chemical resistance, as well as physical durability and electrical insulation. Polyethylene also has beneficial lubricity and release properties, allowing viscous substances to be removed from a polyethylene-coated surface with relative ease.

 

LDPE-based and LLDPE-based coating powders are characterized by high corrosion resistance, chemical resistance and good insulation qualities. When used with special finishing or additives, they have good UV and weathering resistance, which means they are also well suited to outdoor use. The melting point is between 110 °C and 125 °C.

 

The benefits of polyethylene coatings are; strong adhesion to most metal parts, Excellent resistance to impact, wear and tear, High corrosion resistance for longer lifespan, Superb cost efficiency, free of maintenance

Polyamide Coating

Polyamide coatings are the most common thermoplastic powder compositions. They have a beautiful appearance, high hardness, strength, resistance to abrasion, resistant to chemicals and solvents. There are compositions that do not require a primer, and inks which are applied to the pre-primed surface. In the case of critical surfaces (protection of dishwasher’s basket, pipes, valves, pumps, chemical equipment and medical instruments) priming is usually carried out. With an appropriate choice of raw materials polyamide coating is approved for food contact.

 

Polyamide coating is used not only for interior but also for exterior use, such as painting of lighting, poles or benches.

​

These powder coatings provide a durable protective layer with a high level of wear, impact, and abrasion resistance. Polyamide has a low friction yield when applied over a primer. Coupled with its lubricity, this makes it well-suited for products that have sliding or rotating parts, such as automobile spine shafts.

​

Polyamide powders are suitable for coating highly stressed surfaces. They are characterized by good strength, stiffness, durability and mechanical flexibility. The surface coatings have good resistance against chemicals, abrasion and wear, and are virtually insusceptible to stress cracks.
