What is Powder Coating?
An environmentally friendly and cost effective alternative
Once the required ingredients have been pre weighed, they are dry mixed before being extruded. This process melts the mix, activating the resin and hardeners before it is rolled flat on a conveyorised belt. The now cool mix is broken down in to chips, ground and then finely sieved to ensure no large particles contaminate the powder.
Recoverable & re-usable
Powder coatings are a combination of the following raw materials
Curing Agents
Curing agents (or hardeners) are crucial chemical compounds that react with the resin (binder) when heated, causing cross-linking to form a tough, durable, three-dimensional polymer network, transforming the powdery finish into a solid, functional coating with desired properties like hardness, flexibility, and chemical resistance.
Additives
Various with a wide range of properties for example; degasser to help the air escape from the substrate during the curing process therefore helping to restrict pin holing.
Tint Pigments
Tint pigments are finely ground organic or inorganic particles that provide the finished coating with its specific colour, opacity, and sometimes special effects (like shimmer or fluorescence), determining its final appearance after curing.
Effect Pigments
Mica (artificial metallic) for external applications as actual metal will oxidise. Aluminium for internal use only products.
Extenders
Extenders help create matte finishes (the more extender = more matte), support the coating structure, and provide properties like scrub resistance, opacity, and adhesion, making them crucial for performance and cost-effectiveness in various applications.
Titanium Dioxide
White pigment used in all coatings, amongst other properties it helps to create brightness by dispersing light.
