Abstract:

As the industrial market shifts towards new and increasingly waterbased polymer dispersions, the need for biocides to protect the integrity of the finished product increases.   When fouled, polymer dispersions may exhibit a number of undesirable side-effects such as viscosity reduction, separation, and production of gas or odor.  The diversity and complexity of these new systems presents a challenge to biocide selection.  In industrial applications of polymer in waterbased systems (e.g. paint and coatings, adhesives, and sealants), analytical testing of the system enables a formulator to maximize the efficacy of the biocide, and protect the integrity of the product.  Proper analytical screening including assay determination via high pressure liquid chromatography, redox potential, pH measurement and general raw material compatibility testing helps in the development of an effective microbial protection program to inhibit and/or control the growth of microorganisms that cause biodeterioration.  This paper will address some key areas where analytical testing can provide critical information to ensure the optimal protection of polymer dispersions.
