Antique Bronze Finish Interior Design Decorative Metal Sheet In PVDF Rainbow Color Coating

Description Of PVDF Coated Metal Sheet

This is a retro decorative metal sheet in PVDF rainbow color coating.It uses galvanized steel plate as the base material, and its surface is sprayed with PVDF and dried to form a retro and old-fashioned effect with rainbow colors. It is the most popular interior decoration material this year.

This kind of PVDF coated metal sheet not only has super color retention, the color can be stable for 20 years, but also has good corrosion resistance and acid resistance, making it the best choice for outdoor and indoor decoration materials.

What Is PVDF Coating ?

PVDF coating (polyvinylidene fluoride) is the best existing organic coating, offering great colour retention and corrosion resistance. It is made of 70% fluorocarbon resin and 30% acrylic resin, with special weather-resistant pigments. With fluorine resin as the main film-forming material, PVDF is a perfect protective coating for metal building panels, such as steel,stainless steel,aluminum and galvanized steel. Its service life can reach 25 years under normal conditions. While it is also suitable for highly corrosive environments.

Compared with traditional paintings, PVDF coating has better weather resistance and superior resistance to corrosion, UV, pollution, and scratch. It will maintain its color and luster after 20 years outdoors. Also, it is available in a wide range of colors.

Advantages of PVDF Coating

1. Excellent Weather Resistance

PVDF coating contains 70% fluorocarbon resin with a large number of F-C bonds, which determines its super stability. So it has superior resistance to weathering by ultraviolet light, moisture, or temperature. Its surface will not powder or fade for more than 20 years outdoors.

2. Super Corrosion Resistance

Thanks to its excellent resistance to chemicals, such as acid, alkali, salt, etc., PVDF coating will provide a protective barrier for the base metal. Besides, PVDF coating is 6-10 times thicker than the ordinary coating. The thick coating offers high surface hardness and good wear resistance.

3. Excellent High and Low Temperature Resistance

PVDF coating is applied to metal at a temperature of 200°C above, and on the lower surface using EP epoxy powder thermosetting resin, which can be used at 150 °C. After 10 times of freezing-thawing experiments, the resin layer did not fall off, heave, crack, peel, damage and other phenomena. The coating can be used in the temperature range of -60 ℃ to 150 ℃ for a long time.

4. Maintenance-free and Self-cleaning Performance

PVDF coating has very low surface energy, and the surface dust can be self-cleaned by rain. Besides, its maximum water absorption rate is less than 5% and its minimal friction coefficient is 0.15 to 0.17. So it will not stick to dust scale and oil.

5. Strong Adhesion

PVDF coating has excellent adhesion on the surfaces of metals(steel,stainless steel,aluminum,galvanized steel), plastics cement, and composite materials.

Q1：What is PVDF coating?

A1：PVDF stands for Polyvinylidene Fluoride. It's a high-performance, fluoropolymer-based resin coating applied to metal sheets (like stainless steel,aluminum, steel, or Galvalume) primarily for architectural building envelopes (roofing, wall cladding). 

Q2：What is the typical composition of a PVDF coating system?

A2：A high-quality PVDF system usually consists of:

1. Primer: Enhances adhesion to the metal substrate and provides additional corrosion protection.
2. Color Coat: Contains at least 70% PVDF resin by weight (industry standard for premium performance) blended with high-quality acrylic resins and premium inorganic pigments.  This layer provides color and UV resistance.
3. Clear Topcoat (Often used): A protective layer of clear PVDF resin (sometimes modified) that further enhances gloss retention, dirt pickup resistance, and chemical resistance.
 

Q3：How thick is the PVDF coating?

A3：Total coating thickness typically ranges from 20 to 35 microns (0.8 to 1.4 mils).  This is significantly thinner than polyester (PE) coatings but offers much better performance due to the resin chemistry.

Q4: What substrates are PVDF coatings applied to?
A4: Primarily:

1. Aluminum: Most common for wall cladding, soffits, and architectural elements.
2. Galvanized Steel & Galvalume (AZ): Widely used for roofing, wall panels, and structural profiles.  Requires a compatible primer system for optimal corrosion resistance.
3. Stainless steel:Most common for interior design.

Q5: How durable is PVDF coating?
A5: Extremely durable.  PVDF coatings are known for their ability to withstand decades of harsh weather exposure while retaining color and gloss significantly better than polyester (PE) or silicone-modified polyester (SMP) coatings.  Lifespans of 20+ years are common.

Q6: Does PVDF coating fade?
A6: PVDF coatings exhibit excellent fade resistance, far superior to PE or SMP.  While all pigments fade slightly over decades under intense UV, PVDF minimizes this effect dramatically.  High-quality inorganic pigments used with PVDF further enhance fade resistance.

Q7: Is PVDF coating easy to clean?
A7: Yes.  Its smooth, non-porous surface and chemical resistance make it highly cleanable.  Dirt, pollutants, and grime generally rinse off easily with rain or mild cleaning solutions (water and mild detergent).  Avoid harsh abrasives or solvents.

Q8: Is PVDF coating more expensive than other coatings?
A8: Yes, PVDF coating is typically the most expensive option among common coil coatings (PE, SMP, PVDF) due to the higher cost of the fluoropolymer resin and premium pigments.
