Transparent Fluoropolymer Powder Coating

Surface Finish Options Overview

Product Overview

Transparent Fluoropolymer Powder Coating is a high-durability clear powder coating developed with advanced fluoropolymer resin technology. You use it when long-term exterior stability, UV resistance, and gloss retention are critical, while still preserving the original color or metallic texture of the base layer.

It functions as a protective transparent topcoat that enhances corrosion resistance and weathering performance without altering the underlying finish. For architectural and high-end industrial applications, it provides extended service life in compliance with international standards such as ISO 9227 for salt spray resistance and ASTM G154 for accelerated weathering evaluation.

This product is especially suitable for aluminum systems exposed to strong sunlight, humidity, or marine atmospheres.

Features

Long-Term UV Stabilit
You maintain excellent gloss retention and surface clarity even under strong ultraviolet exposure.

High Transparency and Surface Smoothness
The coating forms a clear, uniform film without affecting the metallic effect or base color depth when cured properly.

Enhanced Corrosion Protection
When applied over properly pretreated substrates, you improve resistance against moisture, salt, and environmental pollutants.

Strong Mechanical Performance
You benefit from reliable adhesion, flexibility, and impact resistance, reducing the risk of cracking or delamination.

Environmentally Responsible Technology
As a solvent-free powder coating, it produces no VOC emissions during application and supports environmentally compliant production processes.

Performance System Recommendation

For demanding exterior applications, you can apply a two-layer system:

1. Primer or base powder coating

2. Transparent Fluoropolymer Powder Coating as clear topcoat

This system improves durability and extends maintenance intervals, particularly in coastal or high-UV regions.

Surface Preparation Guidelines

Proper surface preparation directly affects long-term durability. You should use:

• Chromate-free conversion coating for aluminum

• Standard chemical pretreatment compliant with ISO requirements

• Thorough cleaning and degreasing prior to application

Insufficient pretreatment may compromise corrosion resistance regardless of coating quality.

Storage and Handling

• Store in a dry environment below 30°C

• Avoid direct exposure to humidity

• Keep packaging sealed before use

• Use first-in, first-out inventory management

Proper storage ensures consistent application performance.

Case

Commercial Building Curtain Wall – High UV Region

You required a transparent protective topcoat over metallic silver aluminum panels for a commercial building located in a region with strong year-round sunlight.

After application of the fluoropolymer clear coat system and evaluation according to ISO 9227 and ASTM G154, the panels demonstrated stable gloss retention and no visible blistering or peeling. The project achieved long-term aesthetic stability while maintaining the original metallic finish.

Types of powder coating

Powder coatings can be categorized by resin system (epoxy, polyester, hybrid, polyurethane), appearance (smooth, texture, hammer, metallic, pearlescent), or performance level (anti-corrosion, heat-resistant, UV-resistant, architectural grade, automotive grade).

Powder coating colours and effects

Powder coatings offer thousands of colors in gloss, matte, satin, metallic, candy, texture, wrinkle, hammer tone, wood grain, fluorescent, and other custom effects. Special powders can create soft-touch, anti-scratch, anti-fingerprint, or anti-graffiti surfaces.

Powder coating process

The process generally includes surface pretreatment (degreasing, phosphating, chromating, sandblasting), drying, electrostatic spraying, curing in an oven, and cooling. A well-controlled pretreatment and curing process ensures strong adhesion and long service life.

Powder coating benefits

Powder coatings are environmentally friendly, solvent-free, and produce minimal waste. They offer excellent corrosion resistance, weather durability, mechanical strength, and uniform film appearance. The coating is tough, impact-resistant, scratch-resistant, and has a long lifespan.

Applications for Powder Coatings

Powder coatings are widely used in appliances, aluminum profiles, architectural components, automotive parts, bicycles, furniture, outdoor equipment, machinery, electrical cabinets, pipeline systems, and general industrial and consumer goods.

FAQ

What is Powder Coating?

Powder coating is a dry finishing technology where finely ground powder is electrostatically sprayed onto a metal or non-metal surface and then cured at high temperature. After curing, the powder melts into a continuous, durable, and decorative coating layer.

What does powder coating do?

Powder coating protects the substrate from corrosion, weathering, chemical attack, and mechanical wear. It also provides decorative appearance with rich colors, gloss levels, textures, and special effects.

Is powder coating better than paint?

In many industrial applications, powder coating outperforms liquid paint. It forms a thicker and tougher coating, resists corrosion and chemicals better, and does not contain VOCs. It also provides excellent consistency and cost-effective mass production.

Why is it called powder coating?

It is called powder coating because the coating material is a solid powder instead of a liquid paint. The coating is formed by melting and curing powder particles under heat.

What are the different types of powder coating?

Powder coatings include several families depending on resin chemistry:

• Epoxy powders

• Polyester powders

• Epoxy-polyester hybrid powders

• Polyurethane powders

• Acrylic powders

• Fluorocarbon (PVDF) powders

Each type has its own performance features such as corrosion resistance, UV resistance, chemical resistance, outdoor durability, or decorative properties.

Which material is used in powder coating?

Powder coatings are based on thermoset or thermoplastic resins combined with pigments, curing agents, fillers, additives, and in some cases metallic or effect particles. Common substrates include steel, aluminum, galvanized metal, MDF, and certain heat-resistant plastics.

How long will powder coating last?

The lifespan depends on powder type, film thickness, application method, pretreatment, and service environment. Indoor coatings can last more than 10–20 years. High-grade outdoor polyester or fluorocarbon powders can last 15–25 years or longer under UV exposure.
