Abstract
As the industrial market shifts toward new and increasingly water-based 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 water-based systems (e.g., coatings, adhesives, and sealants), analytical testing of the system enables a formulator to maximize biocide efficacy, thus protecting product integrity. Proper analytical screening including assay determination via High Performance Liquid Chromatography (HPLC), redox potential, pH measurement and general raw material compatibility testing helps in the development of an effective microbial protection program to inhibit or control the growth of microorganisms that cause biodeterioration. This paper addresses some key areas where analytical testing can provide critical information to ensure the optimal
