Embodiment Construction

[0008] The following is a detailed description of the present invention.

[0009] As used herein, unless the context clearly dictates otherwise, the following terms have the assigned definitions.

[0010] The term "antimicrobial compound" means a compound capable of inhibiting the growth or controlling the growth of microorganisms; depending on the applied dose level, system conditions and the level of microbial control desired, antimicrobial compounds include bactericides, bacteriostatic agents, fungicidal agents, fungicides, algicides and algicides. Such term "antimicrobial compound" as used herein is synonymous with the term "biocide".

[0011] The term "microorganism" includes, for example, fungi (such as yeasts and moulds), bacteria and algae.

[0012] The following abbreviations are used throughout this specification: ppm = parts per million by weight (weight / weight), mL = milliliter, ATCC = American Type Culture Collection, SAG = University of Göttingen algae culture ...

Abstract

A synergistic antimicrobial composition containing lenacil and one of 4,5-dichloro-2-n-octyl-4-isothiazolin-3-one or 2-n-octyl-4-isothiazolin-3-one is provided. Also provided is a method of inhibiting the growth of or controlling the growth of microorganisms in a building material by adding such a synergistic antimicrobial composition. Also provided is a coating composition containing such a synergistic antimicrobial composition, and a dry film made from such a coating composition.

Description

technical field [0001] The present invention relates to combinations of antimicrobial compounds and their use in dry film protection applications, which combinations are unexpectedly more active than would be expected when using two individual antimicrobial compounds. Background technique [0002] Using a combination of at least two antimicrobial compounds can broaden the potential market, reduce use levels and costs, and reduce waste. In some cases, commercial antimicrobial compounds fail to provide effective control of microorganisms even at high use concentrations due to poor activity against certain types of microorganisms, such as those resistant to some antimicrobial compounds those microbes. Combinations of different antimicrobial compounds are sometimes used to provide overall control of microorganisms in a particular end-use environment. For example, WO1998 / 121962 discloses the combination of 3-iodo-2-propynyl butylcarbamate and pyrithione, but this reference does...
