What is PVDF/ KYNAR Coating?
PVDF coatings (polyvinylidene fluoride) or Kynar® is a chemical resistant thick film barrier coating primarily used on architectural coatings that has exceptional weathering characteristics. This coating is unaffected by most chemicals and solvents and has excellent wear and abrasion resistance. PVDF coatings also have a high dielectric strength, excellent resistance to weathering and the ability to self-extinguish. PVDF coating is sprayed using electrostatic guns on aluminium and the aluminium is then baked in a curing oven at 270 degrees for 21 minutes. PVDF coating carry a 25 years warranty on aluminium for exterior finishes PVDF coatings are in great demand in the market specifically because it is available in a variety of colours and is more durable.
PVDF (Kynar) coating facility consists of four booths. Kynar coating process consists of five steps:
