What is the difference between thermoplastic and thermoset powder coatings?
Thermoplastic powders soften when heated and harden on cooling, but they can be remelted. Thermoset powders chemically cure during baking and form a permanent, cross-linked coating.
Thermoset coatings are generally more durable, heat-resistant, and resistant to chemicals than thermoplastic powders.
Which powder coating type is best for high-temperature applications?
Epoxy and polyester-based thermoset powders are ideal for high-temperature environments.
They retain adhesion, colour, and performance even under repeated heat exposure, such as on engine parts or industrial equipment.
Can powder coatings be used for food-contact surfaces?
Yes, some powder coatings are FDA-approved for indirect food contact.
These coatings are non-toxic, durable, and easy to clean, making them suitable for kitchen equipment or packaging machinery.
What is a polyester powder coating?
Polyester powders provide excellent weather resistance, UV stability, and colour retention.
They are commonly used for outdoor metalwork, architectural structures, and garden furniture.
What is an epoxy powder coating?
Epoxy powders offer excellent adhesion, chemical resistance, and corrosion protection.
They are ideal for indoor metal parts, machinery, and components exposed to moisture or chemicals.
Which powder coatings are UV resistant?
Polyester, TGIC-polyester, and some polyurethane powders are highly UV-resistant.
These coatings maintain colour and gloss even under long-term sun exposure, making them ideal for outdoor applications.
Can powder coating be applied to aluminium?
Yes, aluminium can be powder coated after proper surface preparation such as cleaning, degreasing, and chromating.
Powder coatings enhance aluminium’s corrosion resistance and aesthetic appearance.
Are there anti-graffiti powder coatings?
Yes, certain powder coatings include anti-graffiti properties that make cleaning paint and markers easier.
These coatings are durable and commonly used in public spaces, signage, and street furniture.
How do you choose the right powder coating type?
Consider the application, environmental exposure, substrate material, and desired finish.
High-performance coatings, UV resistance, and chemical resistance requirements should guide your selection.
What are the common finishes available for powder coatings?
Finishes include smooth, textured, metallic, gloss, matt, wrinkle, stone, and leatherette effects.
Choosing the right finish depends on aesthetics, durability needs, and functional requirements.
