Consumers expect the paints they purchase to have a long shelf life. Most consumers expect paint products to be free of microorganisms until the final drop of the paint is used. There are no silver bullets to guarantee in-can protection, especially considering that paint companies have no control over how their paints are stored after purchase. Assessing likely uses and constantly evaluating plant hygiene will help formulators looking for the optimal bocide combination for their in-can preservation.

Importance of analytical testing in biocide selection for polymer dispersions / Matthew Besterci in COATINGS WORLD, Vol. 23, N° 7 (07/2018)  

[article]  inCOATINGS WORLD > Vol. 23, N° 7 (07/2018) Titre : Importance of analytical testing in biocide selection for polymer dispersions Type de document : texte imprimé Auteurs : Matthew Besterci, Auteur ; Cecilia McGough, Auteur ; Wilson Nova-Ruiz, Auteur Année de publication : 2018 Note générale : Bibliogr.

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 protection of polymer dispersions.
