Description

D-90G Properties

D-90G is a dry penetrant developer. It has great resistance to the phenomenon of segregation. It is made of 100% mineral powder, with a white matte finish for reduced UV reflections. it can be accompanied by all fluorescent penetrants.

Instructions for D-90G Use

Immersion:

After washing and drying the parts, immerse them for 5 to 10 seconds into the developer. Take them out and let them bleed for at least 10 minutes. The developer should be homogenized (using a wooden spoon, for example), twice a day.

Dust chamber:

Once washed and dried, the parts are inserted into the dust chamber. They are to be placed at mid- height of the tank (which is closed). A very small quantity of powder, at the bottom of the tank, is stirred by a fan, or by a blow of compressed air (dry and oil-free: in that case, exhaust should be directed outside the workshop with a particles filter) for approximately 30 seconds. Then let the parts dry for at least 10 minutes in the compartment, so that the powder can fall down before opening.

Spray:

D90G can be applied by pneumatic spraying (dry, oil-free air). However, electrostatic spraying is preferable, as it makes it possible to apply a thin layer of developer, which remains clean at all times.
