Product description: VINNAPAS® EF8300 is an aqueous dispersion of a vinyl acetate-ethylene (VAE) copolymer. It was developed as a higher performance polymer for interior architectural coating formulations with environmental advantages. This technology can replace a variety of technologies including:- Vinyl acrylic/acrylic blends
- Vinyl acrylics with wet adhesion
- Pure acrylics
Properties: As a broad application binder for architectural coatings, VINNAPAS® EF8300 combines excellent performance (including good block resistance, scrub resistance, and wet adhesion) with the ability to formulate low VOC paints. 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. Many commercial binders used today, especially conventional vinyl acrylics and pure acrylics, suffer significantly in performance when formulated at lower solvent levels. VINNAPAS® EF8300 requires little to no coalescing solvent, which allows formulators to develop high performance coatings even in low VOC paints. VINNAPAS® EF8300 is in compliance with any major foreseeable requirements in the coatings industry:- It does not use any surfactants or defoamers that contain alkylphenol ethoxylates (APEOs).
- It is manufactured without the use of any formaldehyde donors.
- It enables the formulation of low volatile organic compounds (VOCs) coatings.
- 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.
Application: VINNAPAS® EF8300 was designed to provide a high performance product (where properties such as block resistance, stain resistance, and wet adhesion/water resistance are desired while still maintaining good scrub resistance) with environmental advantages. It has application in contractor and Do-it-Yourself (DIY) products and is recommended for flat through semigloss finishes. VINNAPAS® EF8300 is positioned to replace competitive technologies such as vinyl acrylics, acrylics, and blend systems in interior architectural applications. VINNAPAS® EF8300 is also very compatible with other latex dispersions and can be blended with other polymers such as high Tg pure acrylics to provide excellent block resistance and wet adhesion – properties that are necessary in very high end coatings.Information provided by Wacker Chemie AG. |
