In-Can Preservation for Paints, Adhesives and Related Products

General

BIT-20 biocide is a broad spectrum microbicide for the preservation of industrial water-based products against the attack of microorganisms. The Composition of BIT-20 is 20% solution of 1,2-Benzisothiazolin-3-one in dipropylene glycol and water.

BIT-20 is specifically recommended for the preservation of polymer emulsions, paints and coatings, adhesives, and printing inks.

Typical Properties

These properties are typical but do not constitute specifications

Appearance	Clear amber liquid
Active Ingredient	20%
pH (10% in water)	11.0-13.0
Specific Gravity (g/ml)	1.14 at 25°C
Temperature stability	Stable up to 50°C (for short periods up to 100°C depending on matrix)
pH stability	Stable at pH 4 - 12

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.
