Western Coatings Symposium 2011: WACKER Presents Novel VAE Dispersion for High Performance Coatings
At the Western Coatings Symposium (WCS) 2011, WACKER, the Munich-based chemical group, will present a novel dispersion specifically developed for high performance architectural coatings. The new VINNAPAS EF8300 is a vinyl acetate-ethylene-based copolymer (VAE) characterized by excellent performance properties, including good block resistance, scrub resistance, and wet adhesion. Further, the new dispersion has a reduced environmental impact, as it is manufactured without the use of alkylphenol ethoxylates (APEOs) and formaldehyde donors, and enables formulations with lower solvent levels. This makes VINNAPAS EF8300 ideal for formulating high performance interior coatings at low levels of volatile organic compounds (VOCs). The 30th Biennial Western Coatings Symposium takes place from October 23 to 26 in Las Vegas (Nevada, USA).
Specifically designed for the requirements of interior architectural coatings formulations, the new VINNAPAS EF8300 offers high performance, a reduced environmental impact and a cost-competitive alternative to existing coatings based on vinyl acrylic, pure acrylics or vinyl acrylic/acrylic blends.
The new product is an aqueous copolymer dispersion based on vinyl acetate and ethylene. VINNAPAS EF8300 demonstrates excellent performance properties such as good block resistance, scrub resistance, and wet adhesion to alkyd substrates. It has a low glass transition temperature (Tg) and minimum film formation temperature (MFFT) which provide the polymer with a very low to no cosolvent demand for proper film formation.
With the ever-tightening restrictions on the permissible level of VOCs in coatings, it is becoming more important that the polymers used can be formulated at lower solvent levels without sacrificing performance. The novel VINNAPAS EF8300 requires little to no coalescing solvent in the paint formulation, which allow formulators to develop high performance low VOC (< 5 g/l) coatings. VINNAPAS EF8300 is further produced without the use of APEO surfactants, defoamers or formaldehyde donors and, in addition to that, is very low in residual vinyl acetate monomer (VAM) at less than 200 ppm.
During the technical session of the symposium, WACKER will further present a technical paper on the innovative VAE technology for natural gas-derived binders for high-quality coatings applications.
As one of the founders of VAE technology, WACKER POLYMERS has over 70 years of experience in this field, and is today a global market and technology leader in the area of vinyl acetate-ethylene copolymer dispersions.
