Applications

MB-10 preservative with the very different modes of action of the active agents is particularly effective in preserving a wide range of industrial aqueous-based products from bacterial and fungal spoilage. Application areas include:

l  Preservative for latices

l  Preservative for paints and coatings

l  Water-based adhesives

l  Pigment cakes/dispersions

l  Preservative for Oil-in-Water emulsions

l  Preservative for building materials

l  Household products

l  Preservative for metal working fluids

l  Textile auxiliaries

Packing and Storage

1000kg IBC or 25kg/PE drum.

A shelf life of 1 year is expected if material is stored in sealed original packaging.

Notice: 

At temperatures <-5 °C，BIT and BIT-sodium salts may crystallize. By heating up to max. 50°C and stirring, the product may be dissolved again. The quality of the product will not be impaired.
