Cleaning and degreasing concentrate (1:10) made of renewable raw materials

PREGAN NT 9 K is a highly efficient cleaning and degreasing concentrate for screen meshes. It is used in a dilution of 1:10 with water. PREGAN NT 9 K solutions emulsify contamination and fats and thus make them water soluble. Its formulation has especially been adapted to meet with the requirements of screen printing. PREGAN NT 9 K is therefore better than all conventional detergents. It is suitable for all mesh types and prevents the appearance of pinholes and surface deterioration when coating with direct photo emulsions. In its formulation mainly components which are either made of renewable raw materials or produced biotechnically were used. PREGAN NT 9 K is pH-neutral, free from phosphates and chlorides and is easily biodegradable.
