The inks have to be mixed with 6 % hardener, article no. 357 174. If necessary it will be thinned with water to a viscosity of 20 - 30 sec., measured in a 4 mm DIN cup. The lids of the mixing pails should be kept closed. As the hardener hydrolizes and loses its effectiveness, it is necessary to add another 1 % of hardener to the ink after approx.6 - 8 hours. If the use of defoamer is necessary 0,1 - 0,2 % should be added by stirring.
The amount of hardener has to be weighed and should not be measured in ml because the proportions will not fit. 1 ltr. of white weights approx. 2 kg! If 60 ml of hardener will be added this will result only in 3 % of hardener, not 6%! In addition it is recommended not to mix the total quantity of ink with the hardener but only when needed.
Addition in a thin jet by stirring.
It is absolutely necessary to check the quality of the print and the adhesion during printing process. This has to be done permanently. For this purpose a print proof has to be stored for 30 min. at 60° C. Then it has to be cooked or rinsed with water. After the creasing test the resistance can be checked.
The potlife of the inks is at least 6 - 8 hours. High temperatures reduce the potlife.
The inks should be used within 6 months. Older inks should be checked.
The inks have to be stored cool, frost-free and dry. Always keep lids on cans in use.
The prints should be stored for 4 - 5 days at room temperature before further processing.
The ink group 22/5 stands out due to its excellent elasticity and processability.
Due to the high-resistant pigments in the ink some shades can be achieved only approximately.
Before use it is advisable to make pre-tests. We recommend to send obligatory film samples to Jänecke + Schneemann.
