VINNEVA® LC 0300
  • Functions:Binder
  • Chemical Family:Acetates, Vinyls, Vinylics & Vinyl Derivatives, Acrylics & Acrylates
  • End Uses:Latex Mortar
  • Features:Improved Flexibility, Excellent Adhesion, Excellent Elasticity
  • Physical Form:Dispersion
VINNEVA® LC 0300 is an aqueous polymer dispersion with a low glass transition temperature (Tg). It is produced from the monomers vinyl acetate, ethylene, and acrylate. This dispersion offers excellent elongation, adhesion, and flexibility, making it suitable for various bitumen emulsions. VINNEVA® LC 0300 is compatible with most anionic bitumen emulsions and can also be used with other latexes, modifiers, and VINNEVA® dispersions.

Knowde Brand Highlights

Main Benefits and Application Areas

Adding VINNEVA® to bitumen emulsions can yield one or more of the following benefits:

  • Decreased drying times
  • Reduced residual tack
  • Increased adhesion and wear resistance
  • Higher resistance to hydraulic pressure
  • Fewer antioxidants required

Main Application Areas:

  • Coatings / primers
  • Water barriers
Main Characteristics

VINNEVA® dispersions are based on WACKER’s vinyl acetate-ethylene (VAE) technology. These VAE dispersions show improved or similar properties to competing polymer technologies used in bitumen modification.
