Powder coatings are manufactured and applied on surfaces as free flowing, dry powders. In simple terms, these products do not require a specific solvent to suspend the pigments for the application process. Powder coatings are favourable over the alternatives because they do not contain significant amounts of volatile organic compounds. They also produce thicker and longer lasting coats on surfaces.
The use of powder presents a more refined and uniform appearance. Conventional paint will show differences between horizontally and vertically coated surfaces. Also, you can choose diverse visual effects for a coated surface. There are two main categories of powder coatings: thermoplastics and thermosets. While both have great results, the latter choice is more stable in adverse conditions.
Consider this short discussion on the different thermosetting powder coatings you can choose for your applications:
Epoxy coatings are popular because they are hard and impact resistant. This category of thermosetting coatings is ideal for your usage if you are looking for a functional coating. In general, this coating will protect your surfaces from corrosion and damage associated with impact. It can also promote adhesion of other top coatings on surfaces. On the other hand, you should note that epoxy powder coatings have poor durability, so they are not suitable for constant exposure to adverse conditions.
Acrylic-based powder coatings are designed to produce a clear coating on pertinent surfaces. They are appealing because they have a smooth look coupled with great clarity. In spite of the appearance, this category of poweder coating is strong and highly resistant to chips. Acrylic resins can also be used as additives in other powder coatings. When mixed with other products, they will improve the flow and levelling of the dry powder. They also enhance chemical resistance and stain resistance in some polyester and polyurethane coatings.
Polyester powder coatings are common in most regions around the world. Their popularity can be attributed to the wide availability and accessibility of the polymer compound. Also, they have a wide range of applications, depending on the exact formulation of the product. Regardless of your budget or requirements, you will find a suitable product within this category.
If you would like a powder coating with exceptional resilience in external applications, you should consider selecting fluoropolymer resin products. These have high durability and remain stable when exposed to ultraviolet radiation. They are particularly suitable for architectural usage because they will provide long-term service.
When choosing an ideal product, remember to evaluate the colour and gloss for visual impact.
