Pearlescent Powders

Thermaset Limited offer a range of polyester powder coatings designed for both interior and exterior use.

This range is specially formulated on selected polyester resins and pigments to give a tough decorative finish with excellent outdoor durability, designed for use on architectural applications such as buildings, window frames, fascia and fencing.

Architectural pearlescent powder coatings are an exciting advancement in the world of building design. These coatings not only enhance the visual appeal of structures but also offer practical benefits that make them a popular choice among architects and builders.

What are Architectural Pearlescent Powder Coatings?

Powder coatings are a type of finish applied to surfaces, usually metals, to protect them and give them a decorative look. Unlike liquid paints, powder coatings are applied as a dry powder. This powder is then heated, causing it to melt and form a smooth, durable layer. Pearlescent powder coatings are a special type of powder coating that includes fine pearlescent pigments. These pigments create a shimmering, pearl-like effect, making surfaces look more attractive and vibrant.

Benefits of Architectural Pearlescent Powder Coatings

Aesthetic Appeal

The main reason architects love pearlescent powder coatings is their stunning visual effect. The pearlescent pigments reflect light in different ways, depending on the angle, creating a dynamic and eye-catching finish. This makes buildings stand out and can give them a modern, sophisticated look.

Environmental Friendliness

powder coatings are more environmentally friendly than traditional liquid paints. They do not contain solvents, which means they emit fewer volatile organic compounds (VOCs). This is better for the environment and the health of those applying the coatings.

Durability

Pearlescent powder coatings are not just pretty; they are also tough. They form a hard, protective layer that resists scratches, chipping, and fading. This durability is crucial for architectural applications, where surfaces are exposed to the elements and need to maintain their appearance over time.

Ideal Applications

Pearlescent powder coatings can be used on a variety of materials, including metals, plastics, and glass. This versatility makes them suitable for a wide range of architectural applications such as:

  • Door Frames and Windows>/li>
  • Office and Garden Furniture
  • Facade Cladding
  • Shop fittings
  • Lighting

Properties of Powders

Architectural Polyester Pearlescent Powder Coatings

For maximum protection it is essential to pretreat architectural components prior to the application of Thermaset Limited Architectural Polyester Matt Pearlescent Powder Coatings.

Aluminium
Aluminium components should receive a full multi-stage chromate conversion coating or similar chrome-free pretreatment to clean and prepare the substrate. Detailed advice should be sought from the pretreatment supplier.

Galvanized steel
Galvanized steel requires multi-stage pretreatment with either zinc phosphate or chromate conversion. Depending on the type of galvanizing, degassing or use of anti-bubbling additives may be required. Detailed advice should be sought from the pretreatment supplier.

Ferrous substrates
Ferrous substrates require iron or zinc phosphate pretreatment. Detailed advice should be sought from the pretreatment supplier.

Thermaset Limited Architectural Polyester Matt Pearlescent Powder Coatings can be applied by manual or automatic electrostatic spray equipment, an even dry film thickness of 60 – 70 microns is recommended. Only one batch and one spray run should be used for components that will be visible simultaneously after assembly.

Generally good resistance to acids, alkalis and oil at normal temperatures.
