The story behind the enticing shades of ACP panels: VIVA's Color Coating Lines

VIVA is the only aluminium composite panel manufacturer in India with two colour coating lines that coat aluminium coils of 1000mm, 1220mm, 1250mm, 1500mm, 1550mm, and up to 1670mm. VIVA’s colour coating line works on three-coat two bake technology with the country’s most advanced colour coating line.

A pre-treatment is first done on aluminum coils, followed by chromotherapy. After the process is completed, the coils go in for the first coat of primer. Later, a second coat of paint is applied, and the finished goods are processed.

VIVA uses 70% KYNAR 500 certified PVDF (Fluorinated polyvinyl) paint which conforms to ASTM (American Society for Testing and Materials) and EN (European Nation) standards. KYNAR 500 is a registered trademark of Arkema Inc. Our paints are lead-free.

We also use FEVE (Lumiflon) based paint for exterior application and polyester/PET film for textured surfaces of interior architecture. PVDF has anti-ageing properties, whereas FEVE is used to achieve extraordinary gloss.

We at VIVA can adapt our aluminum composite panel or ACP Sheets to wood, marble, mirror, or any other texture of your choice to suit your architectural needs.

The high-quality coatings of VIVA’s ACP sheets require minimal maintenance, keeping your maintenance costs to a minimum. Both the paints make the ACP board wear-resistant and pollution-proof.

2 Coat Colors

Both of these 2 coat finishes will typically consist of a 5-7 micron primer coat and a 18-20 micron color coat for a nominal dry film thickness of 25(+/-)2 micron

3 Coat Colors

These 3 coat finishes will typically consist of a 5-7 micron primer coat, 18-20 micron color coat and a 5 -7 micron clear coat for a nominal dry film thickness of 35(+/-)2 micron.

Coating Types

Poly Vinylidene Difluoride (PVDF) Coating

A Highly non-reactive thermoplastic fluoropolymer produced by the polymerrization of vinylidene difluoride.

(Warranty 10 years, back to back with KYNAR/HYLAR).

Feve Aluminum Composite Panel Coating

Feve aluminum composite panel is a combination of the advantages of PE coating and PVDF Coating aluminum composite materials. For instance, its glossy and color brightness is the same as for PE coating ACP and its weather resistance is comparable with that of PVDF coating aluminum composite panel.
