Thermoplastic powder coating melts when heated and solidifies upon cooling. Unlike thermoset coatings, it can be reheated and reshaped without chemical change.
Key Characteristics
High flexibility, thick coating build, excellent impact resistance, and superior moisture protection are the key features of thermoplastic powder coatings.
Types of Thermoplastic Powder Coatings
Nylon (Polyamide): Tough, abrasion resistant, and low friction.
Polyethylene (PE): Flexible and impact resistant with good moisture protection.
Polyvinyl Chloride (PVC): Provides thick insulation and corrosion resistance.
Fluoropolymers: Excellent chemical and heat resistance.
Advantages
Thermoplastic powder coatings offer excellent impact resistance, corrosion protection, recoating ability, and electrical insulation properties.
Limitations
These coatings have lower heat resistance, limited color options, and may not be suitable for fine-detail applications.
Applications
Common applications include industrial machinery, automotive components, pipes and fittings, and electrical insulation parts.
