- Use of Additives
- 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 color 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.
