Fast-acting, broad-spectrum in-can preservative.
MERGAL K6N is an effective, broad-spectrum liquid preservative designed to inhibit the growth of bacteria, yeast, and fungi in aqueous systems.
Function/Activity of MERGAL K6N:
MERGAL K6N is typically used in paint-applications at 0.1 to 0.3% by weight of final product.
The level required to protect any particular system depends on a variety of factors: initial level of microbiological contamination, the components of the system, the likelihood of exposure to repeat microbiological intrusions, residual reducing and oxidizing agents, and the temperature and pH of the system.
Suggested use levels should be verified by field trials and are reported as percentage of the end-use product.

Application & Use of MERGAL K6N:
MERGAL K6N is a liquid product easily incorporated into waterborne systems.
MERGAL K6N is recommended for waterborne paints and stuccos,adhesives, pigment slurries, starch solutions and sealants.
MERGAL K6N is also useful in inks, fountain solutions, polymer emulsions, rheology modifiers and wax emulsions.
MERGAL K6N can also be used to preserve detergents, household cleaners and similar products.
MERGAL K6N can be applied to systems with:
pH of 3 up to 9, and
Can be incorporated into processed materials at temperatures up to 60°C in the cooling down phase.
Antimicrobial Activity of MERGAL K6N:
MERGAL K6N has a broad spectrum of efficacy against a wide range of microorganisms.
Examples of organisms controlled by MERGAL K6N are:
Bacteria MIC - Fungi MIC
Bacillus subtilis 0.05 - Aspergillus niger 0.02
Enterobacter aerogenes 0.05 - Chaetomium globosum 0.02
Escherichia coli 0.02 - Penicillium funiculosum 0.02
Proteus vulgaris 0.05 - Ulocladium consortiale 0.01
Pseudomonas aeruginosa 0.02
Pseudomonas flurescence 0.01
Yeast MIC - Algae MIC
Candida albicans 0.02 - Chlorella fusca 0.002
Saccharomyces cerevisiae 0.01 - Anabaena cylindrica 0.001
Formulation Considerations of MERGAL K6N:
MERGAL K6N is a liquid product easily incorporated into waterborne systems.
For best results, MERGAL K6N should be added as early in the production process as possible.
If high temperatures or highly alkaline pH values are expected during production, the product should be added after these conditions are controlled or to add 1/3 of MERGAL K6N in the beginning and 2/3 at the end of the process
MERGAL K6N is compatible with most known systems.
The presence of strong reducing agents may result in the degradation of the actives.
Incompatibilities might occur with materials which can be cross linked like protein based adhesives.
Due to various possibilities of application and different methods of processing, MERGAL K6N is advised to check compatibility in the development of new products.
Storge of MERGAL K6N:
Keep container tightly closed.
Use only with adequate ventilation.
Always protect from direct sun light and heat sources.
Avoid temperatures higher than 40°C.
Longest shelf life is achieved if stored between 5 - 25°C.
Keep from freezing.
Store away from incompatible substances in a dry and ventilated area.
Do not store near food or feed.
Shelf Life of MERGAL K6N:
24 Months from date of manufacture.
Saffety of MERGAL K6N:
While handling MERGAL K6N, the usual precautions for preservative have to be taken.
Contact with the concentrate should be avoided.
While handling MERGAL K6N, protective clothing and safety goggles have to be worn. If splashes get onto the skin, wash immediately with plenty of water and soap.
If splashes get into the eyes, wash with plenty of water and consult a physician.
Contaminated clothing must be removed immediately.
