Anti-Bacteria properties of BBIT

BBIT effect can be evaluated by available minimum inhibitory concentration. Minimum inhibitory concentrations does not mean the usage effect, but it stands for the broad-spectrum antimicrobial activity of BBIT. BBIT has more effect on controlling mildew and fungi erosion, especially in high temperature. BBIT is a good choice of fungicide for plastics, polyurethane and other polymer materials.
