Unravelling The Coating Process

At its core, the coating process involves applying a protective and decorative layer of dry, free-flowing powder. This process is distinguished by its application method – electrostatically, which imparts a charge to the powder, followed by heat curing. This results in a hard, uniform, and resilient finish that resists wear and tear. Its enhanced durability and aesthetic versatility make it ideal for architectural projects.

The Different Types of Powder Coatings

  • Epoxy Powder Coatings: Known for their excellent chemical resistance and great mechanical properties.
  • Polyester Powder Coatings: Popular for their good chemical resistance and excellent weathering properties.
  • Polyurethane Powder Coatings: Valued for their excellent flow, good mechanical properties, and superior weathering resistance.
  • Acrylic Powder Coatings: Chosen for their excellent clarity, gloss, and UV resistance.

The Importance of Powdering Coating in Architecture

In the architectural industry, durability is crucial. Structures must endure various environmental factors, including weather conditions, UV rays, and corrosion. The high-performance coating features an inherent ability to resist these environmental challenges better than traditional painting methods, making it a go-to option for architects and builders. Additionally, its wide range of colours and finishes allows architects to realise their creative visions while ensuring their designs’ longevity.

The Process

The architectural powder coating process begins with pre-treatment, which involves thorough cleaning and preparation of the surface. Following this, the dry powder is applied using a powder applicator. The powder particles adhere to the surface through an electrostatic charge, providing full, even coverage. The final step is heat curing, which forms a hard, durable finish.

Advantages of Powder Coating Aluminium

  1. Durability: Powder coating provides a more durable finish than paint, resisting chipping, scratching, and fading.
  2. Aesthetic Flexibility: Available in a wide range of finishes, allowing for greater design flexibility.
  3. Environmental Impact: Powder coating is more environmentally friendly than traditional paint as it doesn’t require a solvent, reducing the emission of volatile organic compounds (VOCs).
  4. Cost Effective: Powder coating often requires fewer coat’s than traditional paint, reducing labour and material costs.
  5. Maintenance: Coated surfaces are easy to clean and require less maintenance than other finishes.

What is TGIC?

TGIC (triglycidyl Isocyanurate) is a cross-linking element used in polyester powder coating. It plays a significant role in enhancing the durability and quality of the finish. However, there’s an alternative cross-linking chemistry known as HAA (beta hydroxyalkyl amide), also referred to as TGIC Free, Non-TGIC, or Primid.

TGIC Powder Coatings vs. Non-TGIC Powder Coatings

While both TGIC and Non-TGIC (HAA) powder coatings offer excellent performance, there are some differences between them. TGIC coatings are known for their excellent outdoor durability and chemical resistance. On the other hand, HAA coatings, while also durable, are recognized for their superior overbake resistance, which can be beneficial in applications where a higher cure temperature is required.

Applications of Powder Coating In Architecture

The versatility of coating makes it suitable for various applications, including cladding, balustrades, signage, and public buildings. Its broad range of ral colours and finishes allows architects to match any design or style, making it a preferred choice for both interior and exterior applications.

Comparison: Architectural Powder Coating vs Other Finishes

Compared to other finishes like liquid coatings or anodizing, powder coating offers several advantages. It’s more environmentally friendly as it doesn’t require a solvent, offers higher gloss retention, and is more resistant to chipping, corrosion, and fading. This makes it particularly suitable for architectural applications that require a high aesthetic appeal and longevity.

Overcoming Challenges

Despite its numerous advantages, like any process, architectural powder coating does present some challenges. These can include issues with adhesion, colour consistency, and overspray. However, these challenges can be efficiently managed and mitigated with proper surface preparation, careful application, and comprehensive curing, ensuring a high-quality finish.

Looking forward, the coating industry is set to witness exciting developments. From new, innovative powder technologies to enhanced environmental and economic efficiencies, the industry is poised for significant advancement.

From our own previous bad experiences with liquid paint at Sundance Architectural Products, LLC we began using powder coating for all of our projects. To us, powder coating Orlando area buildings and metal structures should almost be a must! Most renovation projects start because the paint is beginning to fade away. This makes the whole structure begin to look old and dull! While we are certainly all for starting new projects, we recognize it’s not cost effective or wise at all to repaint with the same type of liquid base paint that essentially failed you in the first place! Sure, your product will potentially look the part for a couple of months, but sooner rather than later you will be right back to where you started.

The powder coat is applied by airbrush then heat treated to form a thicker coat that will stick to the surface for a longer period of time. With a proper powder coating application, things like the gates and doors around your house will have a clean look for a longer period of time. With the amount of rain and sun they get every year in the Orlando area you will definitely appreciate the extra help and not having to repaint every year.
