About VAE dispersions and grade selection
What is a VAE dispersion?
A vinyl acetate-ethylene (VAE) dispersion is an aqueous dispersion of a copolymer of vinyl acetate and ethylene. It acts as a polymer binder in adhesive formulations, forming a film as it dries. The properties of this film depend on the polymer composition and grade. Ethylene contributes flexibility to the polymer film.
A VAE dispersion should be selected for the intended formulation and bonding process. Suitability for use without further formulation, compatibility with additives and final bond performance must be assessed for the selected grade.
Selecting a dispersion for an adhesive formulation
Start with the substrates to be bonded, the application method and the service conditions of the finished product. When comparing grades, consider:
- Solids content — for formulation calculations and assessment of the water to be removed during drying.
- Viscosity and measurement conditions — to assess suitability for the intended application method.
- Glass transition temperature and minimum film-forming temperature — to assess film properties and film formation conditions.
- pH and formulation compatibility — when incorporating fillers, plasticizers and other additives.
- Adhesion, setting behaviour and bond resistance — as determined by testing the finished adhesive on the intended substrates.
Compare data obtained using equivalent test methods and conditions. Similar viscosity alone does not make two dispersions interchangeable.
