Session 5: Architectural Coatings I
Vinyl acetate-ethylene copolymers (VAE) emulsions have been widely used to formulate environmentally friendly, low odor and low VOC interior architectural paints for many years. VAE based paints offer superior scrub resistance and excellent touch-up properties. However, conventional VAE emulsions do have some inherent drawbacks. For example, non-flat paints based solely on VAE binders exhibit relatively poor block and dirt pick-up resistance. Typically, paint formulators overcome these limitations by blending VAE with acrylic in higher sheen paints, resulting in higher cost and complexity of the paint formulation.
In this paper, we discuss how new techniques, such as Inclusion Technology, can be used to modify VAE’s morphology and chemistry. In addition, we will show how these new generation VAE exhibit much improved performance properties, including block and stain resistance, when compared to conventional VAE. By overcoming the deficiencies of VAE, formulators are enabled to expand VAE’s usage into exterior applications, as well as using VAE as the sole binder in non-flat paints.
