Viva has made its name in the national and international market with it’s impeccable aluminium composite panel  sheet range. Vibrant colorful sheets with versatility in texture make these sheets popular in the market. To expand the product range, Viva has introduced colour coated aluminum coil.

So, What is Colour Coated Aluminum Coil?

The color-coated coils are aluminum coils that are colored with fluorocarbon coating or polyester color coating. These are colored with PVDF/FEVE paint which is acquired from reputed paint manufacturers. To name a few, PPG, Spectrum, and NIPPON.

The colors are stain-resistant and scratch resistance. To ensure the paint lasts long, 2-3 coatings is done and then baked at high temperature. The paint is cured to generate 25-30 micron thickness over the cold coils.

What Makes Viva’s Colour Coated Aluminium Coil Better?

When it comes to what makes Viva’s colour coated aluminum coils better than their competitors, then the answer is quality. At Viva accelerated weather meter test is conducted to check weather resistance, while salt and spray testing is conducted to check the warranty of the paint.

Apart from these advanced tests, Viva ensures the coils maintain their range of qualities. Some of them are:

Fire-retardant

Aluminum is not a combustible element. Its melting point is 600 degrees Celcius, so even in case of a fire accident, there is little chance that aluminum will burn to cause harm to the products.

The high resistance to heat makes it a suitable material for cooking appliances and electrical appliances.

Sustainable and Environment Friendly

These coils contain PVDF/FEDE coating, which contains active molecules to promote the formation of a protective layer on the surface. These colors do not emit any toxic gas or release VOC gas into the air. Making it easy to recycle and fulfill environmental standards.

Uniformity of Colour

The coils do not have any deformity or distortion of color, which is common in spray paint. These colors are long-lasting and durable. These coils are useful in the cladding industry for manufacturing aluminum composite panels or solid aluminum panels.

Strength

The aluminum coils are flexible and malleable. It is easy to cut, slit, drill, joint fix, and do edge compression. The coils can be bent and shaped in shape according to requirements.

Visually Eclectic

The coils are visually excellent in look. At Viva, we provide PE coating on the coils which gives either matt or glossy texture. Apart from that, there are hundreds of colors available in the coils

The feature that makes Viva, better than its competitors, is its customization feature. The color-coated coils can be customized in any color or shape. These have high gloss retention and weather resistance. Viva uses lead-free paints which have elongation properties and less chalking ensuring it gives a better texture to the coils.

Conclusion

Viva is one of the leading manufacturers and exporters of colour coated aluminum coils in India. With its connection and transportation on fleet ensure on-time delivery and extensive export.

Viva gives 30 years of warranty on each aluminum coil cold roll. The demand for these coils is extensive in residential, and commercial complexes in form of aluminum composite panel cladding, while apart from that, it is common to use in roofs, ceilings, corners of cabinets, easy-to-open cans, and other electronic products.

PVDF and FEVE resin based coatings. What’s the difference?

Powder coatings are increasingly popular as the performance coating choice! What's not to love - seriously good weathering and durability protection (meets and exceeds the performance requirements of AAMA 2605), superior scratch and mar resistance, and a significantly better environmental footprint when compared to liquid coatings!

All good, but it has to be said, sometimes there is some confusion, especially when it comes to the different resins used in performance Fluoropolymer powder and liquid coatings. Read on for a basic guide to AAMA 2605 Fluoropolymer powder coatings.

Architectural coatings that meet and exceed the performance requirements of AAMA 2605 can be based around two different types of resin:

FEVE resin (fluoroethylene vinyl ether)

PVDF resin (polyvinylidene difluoride)

Most of us have heard about PVDF resins in traditional liquid paints. Liquid 70% PVDF, 2 coat+ paint sytems are based on PVDF resins. PVDF resin based powder coatings are also available, and these powders are also 2 coat systems.  FEVE resins are used in many architectural grade powder coatings and due to their unique resin make up are single coat systems that give the same or better performance as a 2 coat system.

This is what the PVDF resin chemical structure looks like  -

This is what the FEVE resin structure looks like. 

Ultra-weatherability, durability, and chemical resistance are derived from the distinctive alternating fluorinated units. Let's get scientific for a moment. The FEVE resins are usually reacted with aliphatic isocyanates to form crosslinked FEVE coatings.  FEVE based fluoropolymer coatings take advantage of the carbon/fluorine bond, which is extremely difficult to break. Carbon-fluorine bonds can absorb much greater amounts of UV energy and will keep this energy from affecting the weaker bonds/linkages in the FEVE resin polymer structure.

So what are the differences and similarities between FEVE and PVDF resins?

Both FEVE and PVDF resin based coatings are factory applied finishes, requiring a spray and bake application process. Both will meet and exceed the performance requirements of AAMA 2605. For this reason the same type of warranty is also available when applied to architectural aluminum by a registered applicator and both are available in solid and metallic or mica finishes. Powders are even available in a light texture. 

However, there are some differences and this can be where confusion sets in.

Thermoset vs. thermoplastic

PVDF systems are thermoplastic. FEVE systems are thermoset. The thermoplastic PVDF resin will “remelt” under high temperatures and pressures while the FEVE resin is a thermoset system that will not “remelt” once it is correctly cured. These thermosetting properties also give the FEVE resins superior toughness and scratch and mar resistance.

Number of coats

PVDF based liquids and powders, must be a minimum of 2 coats. A primer coat is required to add protection and work with the top coat to give the desired levels of durability and protection. In fact the number of coats can depend on location, color and special effect required - plus performance. Kinda confusing.

FEVE based powders are single coat applications when applied to aluminum. The unique Fluorine-Carbon bond and thermosetting properties of the FEVE resin means the same (or better) levels of durability and protection are executed in a single coat. No primer or clear coat is required. Even for metallic/mica powder coatings. 

Color and gloss

Both PVDF based systems and FEVE resin based powders retain their color and gloss extremely well and will meet and exceed the weathering performance requirements of AAMA 2605. However with FEVE based powder coatings higher gloss finishes are available. The PVDF resins are much more limited in the range of gloss they can achieve as the PVDF resin acts like a matting agent. Because the Carbon-Fluorine bond is part of the resin system in FEVE based systems there is no matting effect.

Manufacturers of PVDF based powders will tell you that this is the superior coating and will have data to prove it. Manufacturers of FEVE resin based powders will tell you that this is the superior coating and will also have data to prove it.  The truth, as always, is somewhere in between. The fact is, both products work well, offer great protection and warranties and are an excellent coating choice. At IFS Coatings we use FEVE based resins, along with many of our competitors.  We believe there are many, many more examples of FEVE resin based powder coatings out there than PVDF powder projects, and they have been shown to be successful time after time after time.

From a sustainability perspective, we know that FEVE resin based powders are a better choice. For architectural practices that claim to practice sustainable design, making the switch to powder should be a no brainer. Not is there no solvent and therefore negligible VOCs, less product and less energy is used in the application process and chrome pretreatment and primer can be completely removed from the process. Most 70% PVDF liquid paints need a chrome based pretreatment AND a chrome based primer, especially to get a warranty. FEVE resin based powders will perform on top of both chrome and non-chrome pretreatments.
