Hardener must be used in an appropriate ratio to the ink. Strong deviations from the noted ratios above can lead to problems. Some problems may take a while to show and can eventually affect resistance and adhesion. Thus, after adding hardener and then thinner – this order is very important – the mixture should rest for approx. 15 minutes so that optimum ink flow and adhesion are achieved. Hardener only to increase the chemical resistance. Pot life can be reduced by approx. half for metal colour tones. With some ink types, pot life depends on a direct relationship to roomtemperature (RT) and relative air humidity (RAH). Evaporation rate: the lower the value, the faster the evaporation, f = relative evaporation rate compared to VC and VD. Thinner VP increases ink adhesion onto polystyrol and related materials. Extremely mild thinner to protect PMMA and polystyrene (molded pieces) from stress or tension cracks. The thinner VX does not etch into the surface and as a result can also be used as a cleaner.

Thinner VR contains XYLOL and cannot be classified as non-hazardous like the other solvents. The flash point is < 0°, extra care is to be taken due to flammability! Adhesion promoter MT is not to be added to the ink. Pre-treatment e.g. via wiping objects with an MT-soaked cloth, spraying or dipping them. Bonding Additive MD is a printable “in line” variation of the MT bonding additive and is applied as a single hit prior to the ink application. Bonding additive MT should be added in 10 – 20 % quantities. It does not alter pot life, but does reduce resistance values. General additives can be used for all ink types except for oven cured inks, UV inks and TPC 301. Retarder agents are used for more specialized applications in which a defined thinner-retarder ratio is used. requires UV-Light exposure (mJ / cm2) in order to fully cure the ink. free of cyclohexanone and condiments x = suitable
