We use the RAL color(most popular Central European color standard) for powder coating. Our main Ral color include classic color such as RAL 9016(Traffic white), RAL 7035(Light grey), RAL 9005(Jet black) and colorful color such as RAL 5012(Light blue), RAL 3020(Traffic red). Also accept custom RAL color. Here for Custom RAL color for powder coating.

Industry knowledge

What are the special properties of Hybrid Epoxy Polyester Powder Coatings in terms of corrosion protection and weather resistance?

Corrosion Protection:
Barrier Protection: Hybrid Epoxy Polyester Powder Coatings create a durable barrier on the substrate's surface, acting as a shield against corrosive agents. This barrier helps to prevent direct contact between the metal surface and corrosive elements such as water, chemicals, and salts.
Epoxy Component: The epoxy part of the hybrid coating contributes to its excellent adhesion to the substrate, forming a strong bond that enhances the overall corrosion protection. Epoxy resins are known for their exceptional chemical and corrosion resistance.
Inhibition of Rust Propagation: Hybrid Epoxy Polyester coatings can hinder the spread of existing rust or corrosion on the metal surface. The epoxy component is particularly effective in this aspect by encapsulating and isolating corroded areas, preventing them from expanding.
Long-term Protection: These coatings are designed to offer long-lasting protection against corrosion, making them suitable for applications in harsh and corrosive environments.
Weather Resistance:
UV Stability: The polyester component of the hybrid coating provides UV resistance, making it suitable for outdoor applications exposed to sunlight. This helps prevent color fading, chalking, and degradation caused by prolonged exposure to UV rays.
Color Retention: Hybrid Epoxy Polyester Powder Coatings maintain their color and appearance over an extended period, even in challenging outdoor conditions. This is particularly important for applications where aesthetics are essential, such as architectural coatings.
Thermal Stability: These coatings exhibit good resistance to high temperatures, which makes them suitable for applications where exposure to heat or fluctuations in temperature is expected.
Resistance to Environmental Factors: Hybrid Epoxy Polyester coatings can withstand various weather conditions, including rain, humidity, and temperature changes, without compromising their protective properties.

What are the key factors to consider when preparing Hybrid Epoxy Polyester Powder Coatings?

Formulation and Composition: The selection of the appropriate epoxy and polyester resins and their ratio in the formulation is critical. The right combination will determine the coating's overall performance, including its corrosion resistance, weather resistance, adhesion, and mechanical properties.
Raw Material Quality: Ensure that all raw materials used in the formulation, such as resins, pigments, fillers, crosslinkers, and additives, are of high quality and meet the required standards. The quality of the raw materials directly affects the final coating's performance and appearance.
Mixing and Blending: Proper mixing and blending of the raw materials are essential to achieve a homogenous and consistent coating composition. Inadequate mixing can result in variations in the coating's properties and lead to application issues.
Pigmentation and Color Stability: The selection of pigments and their dispersion in the formulation should be carefully considered. Pigmentation affects the coating's color, opacity, and color stability under different environmental conditions, including UV exposure.
Curing Agent Selection: Choosing the right curing agent or hardener is crucial for the crosslinking process during the curing stage. The curing agent must be compatible with both the epoxy and polyester resins to ensure proper film formation and desirable properties.
Application Method: The method of applying the powder coating is an important factor to consider. Common application methods include electrostatic spraying, fluidized bed coating, and electrostatic fluidized bed coating. The chosen method can influence the coating's thickness, uniformity, and adhesion.
Pre-treatment of Substrates: Proper surface preparation of the substrate is essential for promoting adhesion and enhancing the coating's performance. Pre-treatment methods may include cleaning, degreasing, phosphating, or sandblasting, depending on the substrate material.
Curing Conditions: The curing process is crucial to achieving the desired properties of the Hybrid Epoxy Polyester Powder Coating. Factors such as curing temperature, time, and heating rate need to be carefully controlled to avoid under-curing or over-curing the coating.
