K-BIO® BM PRESERVATIVE is an aqueous solution of BIT (1,2-Benzisothiazolin-3-one) and MIT (2-Methyl-4-
isothiazolin-3-one) for the in-can preservation of technical products. It has a broad spectrum of activity against
micro-organisms, allowing a robust preservation of a wide range of products such as paints, adhesives, latex
emulsions, tackifiers, mineral slurries, pigment dispersions and other technical water-based products.
K-BIO® BM PRESERVATIVE is a VOC- and AOX-free preparation. It is formulated without the addition of any
organic solvents, halogenated organic compounds, formaldehyde releasing compounds or bivalent metal ions, and
therefore, it is highly compatible in most binder and paint systems.
K-BIO® BM PRESERVATIVE combines the well proven active ingredients BIT and MIT which can provide a long
term and broad efficacy spectrum.
K-BIO® BM PRESERVATIVE is based on active ingredients that comply with European and North American food
contact regulations, e.g., coatings and adhesives, provided that the customary dosage rates are not exceeded.
K-BIO® BM PRESERVATIVE complies with the requirements of the German Blue Angel Ecolabel for interior wall
paints (RAL UZ-102).

Use Recommendation
Typical dose levels of K-BIO® BM PRESERVATIVE is between 0.1– 0.5% in the finished product.
The amount of a preservative to be added is dependent on the susceptibility of the raw materials against microbial
spoilage and their level of contamination. The amount of preservative used can be minimised by observing hygienic
conditions in the storage of raw materials, during production, filling processes and subsequent warehousing.
Our Biological and Technical Laboratories are able to give you professional advice whenever necessary.
Safety, Handling, Storage and Disposal
K-BIO® BM PRESERVATIVE should be stored in tightly closed original containers and preferably at room
temperature. If stored below 5°C precipitation can take place which can be reversed by simple warming up to room
temperature. After a homogeneous mixing K-BIO® BM PRESERVATIVE can be used without any loss in
effectiveness. Protect from light and heat.
