Industrial sterilization, anti-corrosion, anti-enzymes. It has outstanding effects of inhibiting the growth of molds (fungi, bacteria) and algae in organic media, and solves a series of problems such as mold, fermentation, deterioration, demulsification and odor caused by microbial growth. Therefore, developed countries use BIT widely in latex products, water-soluble resins, coatings (latex paints), acrylics, and polymers. Polyurethane products, photo washing liquid, paper, ink, leather, lubricating oil and other products.

Application Field:

BIT biocide is widely used in polymer emulsion, Waterborne coatings, adhesive, Coated paper, Emulsified oil preparation, Oil extraction, industry water treatment system etc.

Product Benefits

1. Broad spectrum activity in high pH systems, controlling bacteria, fungi and yeasts.

2. Stable in the presence of amines.

3. Non specific mode of action, resulting in reduced microbial resistance potential.

4. Ease of handling due to its liquid form and good compatibility in most aqueous compositions.

5. Excellent performance with co-biocides like CMI/MI, bronopol or formaldehyde releasers, which allow performance enhancements and cost reduction.

6. The active ingredient is non-volatile and has a comparatively high heat stability which allows the incorporation in fluids which are still hot.

7. High purity active ingredient, made evident by its clear light colour.
