PVDF Coating
Aesthetics With Durability
India's top companies in architectural coatings associates with Real as its qualified applicator to address the high end expectation of projects specified to AAMA 2605 voluntary specification standards (Organic Coatings on Aluminium Sections & Profiles)
PVDF coatings are made up of inorganic ceramic pigments and PVDF fluoropolymer resin makes them one of the near inert coatings available that strongly resist UV degradation of sun rays thus keeping the facade beautiful for decades while protecting the aluminium from corrosion effect of climatic atmospheric oxidation. In addition to UV resistance PVDF also resist acids, alkalis, detergents, mortar, window and facade cleaners etc thus enhancing the life of the facade beauty.
PVDF Coating Features
Your metal's protective shield
Stain Resistance
PVDF coatings are stain-resistant, ensuring easy cleaning and maintenance, ideal for high-traffic areas.
Chemical Resistance
PVDF coatings are resistant to a wide range of chemicals, including acids, alkalis, and solvents.This makes them suitable for use.
Weather Resistance
PVDF coatings are highly resistant to fading, chalking, and discoloration caused by UV rays, extreme temperatures.
Longevity
PVDF coatings are ideal for high-performance applications requiring lasting aesthetics and low maintenance, like architectural bridges.
Aesthetic Appeal
PVDF coatings offer a versatile palette of colors and finishes, from subtle mattes to shimmering metallics, allowing for customized aesthetic expression.
Ease of Processing
PVDF can be easily processed using various methods, including injection molding, extrusion, and coating. This makes it versatile for various applications.
Mechanical Strength and Toughness
PVDF exhibits good mechanical properties, including high tensile strength, impact resistance, and creep resistance.
Biocompatibility
Some grades of PVDF are biocompatible, making them suitable for medical applications. This means it is well-tolerated by living tissues.
Low Flammability
PVDF is inherently flame-resistant, making it a safe choice for applications where fire hazards are a concern. Its low smoke emission further enhances safety standards.
Good Electrical Properties
PVDF has excellent dielectric properties, making it suitable for use in electrical and electronic applications.

How It Works?
Your Invisible Shield of Strength.
-
PVDF coatings consist of a polymer base of polyvinylidene fluoride resin, often combined with pigments and additives to enhance color and performance.
-
The resin structure provides excellent chemical and physical stability, making it resistant to UV radiation, moisture, and pollutants.
-
The aluminum surface is pre-treated to remove impurities and improve adhesion.
-
A primer coat is applied first to enhance bonding between the metal and the PVDF layer.
-
The PVDF coating is then applied using a spray or roll coating process, followed by curing at high temperatures.
-
Multiple layers may be applied for additional thickness and durability.
-
UV Resistance: The strong carbon-fluorine bonds in PVDF provide high resistance to UV degradation, preventing fading and chalking.
-
Chemical Resistance: The coating resists acids, alkalis, and pollutants, making it ideal for harsh environments.
-
Corrosion Resistance: It creates a protective barrier against moisture and salt, preventing corrosion of the aluminum substrate.
-
Flexibility: PVDF coatings are flexible, accommodating the thermal expansion and contraction of aluminum without cracking or peeling.

FAQ's
PVDF Coating FAQs: Everything You Need to Know
What is PVDF coating, and what are its benefits?
PVDF (Polyvinylidene Fluoride) coating is a high-performance coating known for its superior durability, weather resistance, and color retention. It is commonly applied to metal surfaces, offering excellent protection against UV radiation, corrosion, and harsh environmental conditions, making it ideal for architectural applications and exterior finishes.
How long does PVDF coating last?
PVDF coatings are known for their exceptional longevity. With proper maintenance, they can last 10-15 years without significant color fading or degradation. PVDF-coated surfaces retain their appearance and performance even in harsh weather conditions, making it a preferred choice for exterior applications.
Is PVDF coating environmentally friendly?
Yes, PVDF coatings are considered eco-friendly as they contain low volatile organic compounds (VOCs) and are free from harmful substances. The process produces minimal waste and does not involve toxic chemicals, making it a sustainable choice for green building projects.
