Use cases for Vinyl-Chloride copolymer resins

Vinyl chloride copolymer resins offer unique application advantage is mainly solvent based coatings for aluminium packaging. The main properties of Vinyl-Chloride copolymers are:

  • Thermoplastic
  • Heat sealable
  • High chemical resistance (alcohol, fat, oil, water, acid, alkali)
  • Abrasion resistancy
  • Light resistance upon proper stabilization.
  • Dry coatings and inks are free from odor and taste
  • Coatings are physiologically harmless
  • Strong adhesion on metals
  • Excellent pigment wetting
  • Crosslinkability

There are mainly 2 groups. One has to choose for:

  1. Heatsealable lacquers and Protective coatings
    • High adhesion
    • High seal bond strength
    • High water and alcohol resistance
    • High corrosion resistance.
  2. Printing inks & Primers
    • High gloss
    • Superior Color development
    • Optimal transparancy
    • Good overprintability
    • Low gel content
