Exceptional Surface Protection

The unique hammer-finish texture of this powder coating not only enhances surface aesthetics but also provides robust protection against everyday wear, corrosion, and harsh environmental conditions. Its high adhesion and customizable gloss levels make it suitable for demanding industrial and architectural applications, ensuring surfaces look great and last longer.

Easy and Clean Application

Engineered for application via electrostatic spraying, this polyester powder coating process is both efficient and produces minimal waste. Since the product contains zero VOCs, it's a safer and more environmentally conscious choice compared to traditional liquid coatings. Consistent coverage of 8-10 m2/kg delivers reliable results for both large-scale and precision projects.

FAQ's of Polyester Powder Coating:

Q: How is this polyester powder coating applied to surfaces?

A: This coating is applied using the electrostatic spray method, which ensures an even layer on the desired surface. After spraying, the coated object is cured in an oven at temperatures from 180C to 200C to achieve a durable hammered or structured finish.

Q: What surfaces and industries can benefit from this powder coating?

A: The coating is suitable for a wide range of uses, including architectural components, household appliances, and automotive parts. Its robust physical properties make it ideal for both indoor and outdoor surface protection in demanding industrial settings.

Q: When should I use the hammer or structured finish type?

A: A hammered or structured finish is especially advantageous when you want to hide minor surface imperfections or create a visually textured effect, while also providing extra durability. It's recommended for surfaces prone to scratches or impacts.

Q: What is the coverage rate and film thickness for optimal results?

A: You can expect a coverage rate of 8-10 m2 per kg of powder, depending on the thickness applied. For best performance, aim for a cured film thickness between 60 and 90 microns.

Q: How long can the powder coating be stored, and under what conditions?

A: The coating has a shelf life of 12 months when stored below 25C in a dry environment. Proper storage ensures the powder maintains its properties and applies consistently.

Q: What are the benefits of using this VOC-free, polyester-based powder coating?

A: Since the powder contains zero VOCs, it is safer for health and the environment. Added benefits include high adhesion (100% cross hatch), customizable gloss, and significant durability against corrosion and impacts.

Q: Can I select custom colors and gloss levels for specific projects?

A: Yes, the finish is available in RAL, ANSI, and custom shades with gloss levels ranging from 30% to 70% at 60, allowing for tailored aesthetics to match your project requirements.
