Processing:

1.   Parts have to be cleaned thoroughly from fat, oils or other contamination with WEICON Crack Testing Agent Cleaner and allowed to dry. The flaws have to be open toward the surface.
2.   The processing temperature is in the range of 0°C to +50°C. Apply WEICON Crack Testing Agent Penetrant to the cleaned and dry surface and allow to react for 5-10 minutes.
3.   Remove excess Penetrant from the surface with a lint-free cloth slightly moistened with WEICON Crack Testing Agent Cleaner.
4.   Spray on WEICON Crack Testing Agent Developer from approx. 20 cm distance. Only spray on just enough Developer to produce a white background on the surface. Too much developing agent can cover fine cracks! Cracks and flaws become visible as red lines and dots after a short time. Perform final visual assessment after 5-10 minutes.
