Category: Thermoplastic Powder Coating

Thermoplastic powder coating melts and flows on the application of heat, but continues to have the same chemical composition when it solidifies on cooling. Thermoplastic powder coating is based on thermoplastic resins of high molecular weight. The properties of these coatings depend on the basic properties of the resin. These tough and resistant resins tend to be difficult, as well as expensive, to be ground into the very fine particles necessary for the spray application and fusing of thin films.  Consequently, thermoplastic resin systems are used more as functional coatings of many mils thickness and are applied mainly by the fluidized bed application technique.

Why use thermoplastic coating?

Thermoplastic coatings offer excellent protection of metal structures against corrosion, wear and tear and chemical attack. They outperform other coatings, especially in terms of extended lifetime, environmental impact and ability to protect metal in temperatures down to -70°C.

How To Use Thermoplastic Powder Coatings

The using method of thermoplastic powder coatings mainly include: Electrostatic spraying Fluidized bed process Flame Spray technology Electrostatic Spraying The basic principle of this process is that the electrostatic powder is guided to the surface of the metal workpiece under the combined action of compressed air and electric field when passing through the gap between the spray gun and the grounded metal workpiece. The charged powder adheres to the surface of the grounded metal workpiece, then is melted in anRead More …

Thermoplastic Powder Coatings Types

Thermoplastic Powder Coatings Types

Thermoplastic powder coatings types mainly have the following types: Polypropylene Polyvinyl chloride (PVC) Polyamide (Nylon) Polyethylene (PE) Advantages are good chemical resistance, toughness and flexibility, and can be applied to thick coatings. The disadvantages are poor gloss, poor leveling and poor adhesion. The specific introduction of thermoplastic powder coating types: Polypropylene powder coating Polypropylene powder coating is a thermoplastic white powder with a particle diameter of 50~60 mesh. It can be used in anti-corrosion, painting and other fields. It isRead More …

What is Dip Coating Process

Dip Coating Process

What is Dip Coating Process In a dip coating process, a substrate is dipped into a liquid coating solution and then is withdrawn from the solution at a controlled speed. Coating thickness generally increases with faster withdrawal speed. The thickness is determined by the balance of forces at the stagnation point on the liquid surface. A faster withdrawal speed pulls more fluid up onto the surface of the substrate before it has time to flow back down into the solution.Read More …

What resins are used in thermoplastic powder coatings

Thermoplastic_Resins

There are three primary resins used in thermoplastic powder coating, vinyls, nylons and polyesters. These materials are used for some food contact applications, playground equipment, shopping carts, hospital shelving and other applications. Few of the thermoplastics have the broad range of appearance properties, performance properties and stability that are required in applications that use thermoset powders. Thermoplastic powders are typically high molecular weight materials that require high temperature to melt and flow. They are commonly applied by fluidized bed applicationRead More …

Thermosetting powder coating and thermoplastic powder coating

Polyethylene powder coating is a kind of thermoplastic powder

Powder coating is a type of coating that is applied as a free-flowing, dry powder. The main difference between a conventional liquid paint and a powder coating is that the powder coating does not require a solvent to keep the binder and filler parts in a liquid suspension form. The coating is typically applied electrostatically and is then cured under heat to allow it to flow and form a “skin”.They are applied as a dry material and they contain veryRead More …
