VeoVa™ vinyl ester monomer from Hexion Inc. is a key component in a new specialized binder developed by Vanora for the paint and coatings industry that is environmentally preferred for having no volatile organic compounds (VOCs).

Leveraging Hexion’s VeoCryl Technology

Hexion & Vanora Partner to Create Biocide-free Waterborne Dispersion
Vanora, an innovative polymer dispersion manufacturer located in Sempach, Switzerland, leveraged Hexion’s VeoCryl technology, which combines VeoVa™ vinyl ester and acrylate monomers, to develop a biocide-free dispersion. Biocides are the active chemical molecules that can be used to control or inhibit harmful microorganism growth.

Features & Benefits of DXV.4229


  • The new dispersion known as DXV.4229 contains waterglass, also known as sodium silicate, to increase the pH and a stabilized hydrophobic polymer based on VeoVa vinyl ester 
  • VeoVa vinyl ester provides both alkaline and water resistance, while the water glass ensures good water vapor diffusion
  • DXV.4229 is suitable for use in indoor and outdoor paints and plasters

Meeting Need for a Sustainable Solution


Hexion was pleased to cooperate with Vanora to create a biocide-free alternative for water-based industrial paints,” said Harold Schweitzer, Vice President and General Manager, Versatic™ Acids & Derivatives.

Importantly, the binder DXV.4229 does not emit VOCs and this technology meets the growing need for a sustainable solution in response to recent stringent legislation in Europe that limit the use of biocides in paints and coatings.
