Abstract : DCA-70 is a polyvinyl acetate latex compounded with dibutyl phthalate at a concentration of 10% of the contained solids in the latex. More than thirteen plasticizers were tested for compatibility with the polyvinyl acetate latex used in the DCA-70. Those plasticizers which showed the most promise in the initial screening evaluation were selected for further trials involving preparation of laboratory latex samples, casting of films, and measurement of tensile properties both before and after oven aging and water extraction tests. Nine specification test methods, most of which are standard ASTM procedures for latex products, were applied to various commercial polyvinyl acetate latexes after addition of plasticizers using the formulation developed. Comparison of the data obtained with those attributes expected to be of importance for good performance in dust- control applications leads to a set of tentative specification values which should allow procurement of these products on a competitive basis.
