VC copolymer applications in Aerosol industry

In the aerosol industry, VC copolymers are valued for their flexibility, impact resistance, and adhesion to metals and plastics. VC copolymers are generally solved in a solvent or another polymer solution.

Products Containing VC Polymers

Based on their technical descriptions and industry-standard formulations for these categories, the following products likely utilize VC polymers:

• Anti-Gravel (Stone Chip) Coatings:
  • “Resin-based Anti-gravel Coatings” are described as tough, elastic coatings based on synthetic resins. In the automotive sector, these are almost universally formulated with vinyl chloride copolymers to provide the necessary “damping” effect against road debris and gravel.
  • They are available in black, grey, white, and structured (textured) versions.
• Underbody Protection (UBC):
  • Specifically, the resin-based underbody coatings (as opposed to bitumen-based ones) often use VC polymers to create a paintable, durable barrier that remains flexible even in cold temperatures.
• Structure/Texture Coats:
  • Used in their Bumper & Plastic Repair line, these products imitate the original factory grain of plastic parts. VC resins are often used here to provide the “structure” and “body” required for a textured finish that can still adhere well to plastic.
• Specialty Metal Primers:
  • While Polyvinyl Butyral (PVB) is often used for Etch Primers, other specialty primers or “1K” fillers in their catalog may use vinyl-modified resins to improve chemical resistance and moisture barriers.

Why VC Polymers are Used in These Aerosols

VC polymers (often copolymers like vinyl chloride-vinyl acetate) offer specific technical advantages:

• Impact Damping: Essential for anti-gravel sprays to prevent chipping.
• Paintability: Unlike bitumen/wax, VC-based coatings can usually be overpainted with standard automotive lacquers.
• Chemical Resistance: They provide a dense, impermeable film that protects against road salt and moisture.

VC copolymers are widely used, but often unknown

You will find these formulas under the branding of major automotive aftermarket companies. To confirm if a specific product contains VC polymers, check the Safety Data Sheet (SDS) under “Section 3: Composition/Information on Ingredients” for terms like:

• Vinyl chloride copolymer
• Chloroethylene polymer
• Polyvinyl chloride (PVC)
