The Making of Captivating Colors: Inside VIVA’s ACP Coating Process
VIVA stands as the only aluminium composite panel (ACP) manufacturer in India equipped with two state-of-the-art colour coating lines, capable of coating aluminium coils in widths of 1000mm, 1220mm, 1250mm, 1500mm, 1550mm, and up to 1670mm. These lines operate on the three-coat, two-bake technology, making them the most advanced colour coating systems in the country.
The process begins with a thorough pre-treatment of aluminium coils, followed by chromatising. Once treated, the coils receive a primer coat, then a second layer of paint, before undergoing final processing to ensure flawless finishing.
For durability and long-lasting vibrance, VIVA uses 70% KYNAR 500® certified PVDF paint, adhering to ASTM (American Society for Testing and Materials) and EN (European Nation) standards. KYNAR 500® is a registered trademark of Arkema Inc., and all paints used are completely lead-free.
To meet diverse architectural needs, VIVA also incorporates FEVE (Lumiflon) based paint for exterior applications, while polyester and PET films are used to create textured finishes for interiors. PVDF ensures superior anti-ageing performance, while FEVE delivers exceptional gloss and colour brilliance.
What sets VIVA apart is the ability to replicate natural finishes—whether wood, marble, mirror, or custom textures—bringing architects’ and designers’ visions to life.
Moreover, the high-quality coatings on VIVA ACP sheets are not only wear-resistant and pollution-proof but also demand minimal maintenance, reducing long-term upkeep costs significantly.
