VAE dispersions are based on the polar monomer vinyl acetate and the hydrophobic monomer ethylene. They are produced by emulsion polymerization in an aqueous environment, without the addition of organic solvents. WACKER markets VAE dispersions under the trade names VINNAPAS® and ETONIS®.
Main Characteristics:
The interaction between vinyl acetate and ethylene monomers provides VAE dispersions with an outstanding range of technical performance benefits, along with environmental advantages, at an attractive cost-in-use ratio. For example, flexibility, adhesion and water resistance can be adjusted as needed by varying the monomer composition.
Main Benefits:
Very good adhesion to a wide range of substrates, including wood, paper, metal, plastics and concrete
- Broad range of available glass transition temperatures (Tg)
- The VAE formulation strategy eliminates the need to add plasticizers
- Good film-forming properties at low temperatures and without additional coalescing agents
- Excellent filler acceptance
- Excellent cohesion
- Heat and fire resistance over a wide range
- All modern dispersions are produced without added APEOs
Main Application Areas:
- Adhesives
- Architectural coatings
- Construction
- Nonwovens
- Carpets
- Paper
- Caulks and sealants
