Kevin Merlo.Kevin Merlo Senior Principal Applications Chemist Air Products Polymers Q Why is Airflex[R] EF811 polymer emulsion an excellent binder choice when formulating an interior flat paint with excellent touch-up? [ILLUSTRATION OMITTED] A Good film formation is critical for excellent touch-up. Vinyl acetate/ethylene copolymers (VAEs), such as Airflex EF811 VAE n. 1. See Voe. emulsion, provide enhanced film formation versus other traditional interior latexes, such as vinyl acetate/butyl acrylate Noun 1. acrylate - a salt or ester of propenoic acid propenoate salt - a compound formed by replacing hydrogen in an acid by a metal (or a radical that acts like a metal) copolymers (vinyl acrylics). The use of ethylene, a much more effective plasticizing monomer for vinyl acetate than butyl butyl /bu·tyl/ (bu´t'l) a hydrocarbon radical, C4H9. bu·tyl n. A hydrocarbon radical, C4H9. butyl a hydrocarbon radical, C4H9. acrylate, provides VAEs with a lower minimum film formation temperature (MFFT MFFT Minimum Film Forming Temperature (polymer temperature transition testing instrumentation) ) and [T.sub.g] (glass transition temperature The glass transition temperature is the temperature below which the physical properties of amorphous materials vary in a manner similar to those of a solid phase (glassy state), and above which amorphous materials behave like liquids (rubbery state). ). This results in a polymer that requires little to no coalescing coalescing (kō  les´ing),n a joining or fusing of parts. aid and can form a good film, regardless of temperature or humidity, thus providing a good binder choice when formulating a paint for excellent touch-up. In addition, Airflex EF811 VAE emulsion can be formulated at high PVCs, making it an excellent choice for interior flat paints. Air Products Polymers offers the industry's most extensive line of VAEs for coatings, including Airflex EF811 VAE emulsion, a new product offering with an excellent balance of properties.
