Synergistic combination of a chlorotoluron compound and IPBC for dry film protection
View Patent ↗A synergistic antimicrobial composition containing chlorotoluron and 3-Iodo-2-propynyl butylcarbamate 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.
1. A synergistic antimicrobial composition comprising chlorotoluron and 3-Iodo-2-propynyl butylcarbamate.
2. The synergistic antimicrobial composition of claim 1 , wherein the weight ratio of the 3-iodo-2-propynyl butylcarbamate to chlorotoluron is from 1:5 to 2:1.
3. A method of inhibiting the growth of or controlling the growth of microorganisms in a building material, the method comprising the step of adding the synergistic antimicrobial composition of claim 2 to the building material.
4. A coating composition comprising the synergistic antimicrobial composition of claim 1 .
5. A coating composition comprising the synergistic antimicrobial composition of claim 2 .
6. A dry film made by a process comprising applying a layer of the coating composition of claim 5 to a substrate and drying the coating composition or allowing the coating composition to dry.
