MERGAL K6N
Fast-acting, broad-spectrum in-box preservative
Explanation
Mergal K6N is an effective broad spectrum liquid preservative designed to inhibit the growth of bacteria, yeast and fungi in aqueous systems.
Application and Usage
Mergal K6N is a liquid product that is easily incorporated into water-based systems.
Mergal K6N is recommended for water-based paints and plasters, 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. The product moves fast.
Mergal K6N can be applied to the following systems:
pH 3 to 9, and
It can be incorporated into processed materials at temperatures up to 60 °C in the cooling phase.

Function / Activity
Mergal K6N is typically used in paint applications at 0.1% to 0.3% by weight of the final product.
The level required to protect any system depends on several factors: the initial level of microbiological contamination, the components of the system, the possibility of repeat exposure to microbiological interventions, residual reducing and oxidizing agents, and the temperature and pH of the system.
Recommended use levels should be verified by field trials and reported as a percentage of end use product.
% Weight / Weight
Paint: 0.10 - 0.30
Water-based wood coatings: 0.05 - 0.20
Adhesives, pastes and sealants: 0.05 - 0.20
Polymer Emulsion: 0.10 - 0.20
Printing Inks: 0.10 - 0.30
Formulation Considerations
Mergal K6N is a liquid product that is easily incorporated into water-based systems.
For best results, Mergal K6N should be added to the production process as early as possible.
If high temperatures or high alkaline pH values are expected during production, the product should be added after checking these conditions or by adding 1/3 Mergal K6N at the beginning of the process and 2/3 at the end.
Mergal K6N is compatible with most known systems. The presence of strong reducing agents can cause the actives to degrade.
Incompatibilities may occur with cross-linkable materials such as protein-based adhesives.
Due to the various application possibilities and different processing methods, it is recommended to check compatibility when developing new products.

When working with Mergal K6N, the usual precautionary measures should be taken. Contact with the concentrate should be avoided.
Protective clothing and safety glasses should be worn when working with Mergal K6N. In case of splashes on the skin, wash immediately with plenty of soap and water.
In case of splashes into the eyes, rinse with plenty of water and consult a physician.
Contaminated clothing should be removed immediately.
Shelf Life: 24 months from date of manufacture. Keep container tightly closed. Use only with adequate ventilation.
Always protect from direct sunlight and heat sources.
Avoid temperatures higher than 40°C.
The longest shelf life is achieved when stored at 5 - 25 °C.
Be careful not to freeze.
Store in a dry and ventilated place away from incompatible materials.
Do not store near food or feed.
