Our pocket-sized penetrant system
by R. Dörn, New Business Development, MR-Chemie
"Hello, I've got a problem," is how a conversation for our application experts in the field sometimes start a conversation. In this particular case, it was reported that a small circular weld needed to be inspected. Our dye penetrant system consisting of dye penetrant, intermediate cleaner and solvent-based developer is used for this. The issue that has now been described on the phone is when circular weld is wetted with the penetrant from the spray can, more agent ends up in the air than on the component (overspray). The same applies to treatment with the developer.
As a manufacturer with a close relationship with our customer, we are aware of this issue and our experts have practical solutions for reduce or eliminate overspray. We would be happy to advise you on which solutions might be suitable for you. Perhaps the same solution as the presented here.
How does the application work and what do you need to look out for?
Once the surface is dry after intermediate cleaning, the developer is applied. A difference must now be made in the application. DIN EN ISO 3452 specifies very precisely how a wet developer should be applied. Application with a pen is not taken into consideration in the standard. Therefore, if you need to carry out the process in accordance with the application standard, you should use our classic delivery forms, e.g. the spray can. If you are allowed to deviate from the standard, the developer in a piccolo or jumbo pen is ideal. A small additional tip: do not try to “colour in” the areas, but simply brush over the surface once or twice in the same direction. This will give you a thin and even developer film. The crack indicators, if present, will appear as usual!
For myself, the small piccolo and jumbo pins are great pocket-sized problem solvers. Whether in the industrial sector, engine restoration or crack testing at critical points on high-performance bicycles. In other words, wherever cracks need to be found in small areas.
