RAL1011 Brown beige electrostatic thermoset powder coating for Interior home items
The most commonly used thermoset powder coating resins derive from
the epoxy, hydroxyl or carboxyl, acrylic, and silicone groups. They
generally require lower curing temperatures than thermoplastics,
and manufacturers often introduce additives to accelerate or delay
the curing reaction. It is important to subject a powder-coated
product to thorough heating and allow the thermoset to flow evenly
over the targeted surface because once the thermoset powder has
completed crosslinking, it cannot be reflowed to correct any flaws
in the coating. To achieve successful coating results, it also
necessary to match the thermoset formulation with the product’s
intended corrosion resistance, curing cycle, texture, and aesthetic
properties.
One of the most significant developments in thermoset powder
coating involves the capacity to engineer resin types with variable
properties designed to complement metal finishing treatments. This
broader range of characteristics has led to an increase in
specialized roles for thermoset powders, with polyesters and
acrylics finding greater use in the automotive and appliance
industries despite the traditional reliance on epoxy-based
coatings. Most thermoset powders can provide a high level of
corrosion, temperature, and impact resistance. They can also be
designed with a wide range of colors, glosses, and surface
finishes. Coating texture can be wrinkled, smooth, or matte, while
film thickness is highly adjustable.
