General
Powder developers are used specifically as part of the fluorescent penetrant inspection process and as such, PD3 powder developer is used in conjunction with Britemor penetrants.
When applied correctly, powder developers will enhance the definition and brilliance of indications when viewed under suitable UV light of peak wavelength of 365 nanometres.
Method of Application
PD3 may be applied to the surface under test by dust storm cabinet, electrostatic spray or by hand using a powder bulb.
Final inspection should take place after a developing period of 10 minutes minimum, although some procedures may specify a longer developing time, particularly for the inspection of critical parts.
Appearance
PD3 powder developer is a free flowing, white fluffy powder and is a blend of amorphous, inert white powders with high development capacity. PD3 is asbestos-free.
Typical Properties
Flash Point : Non-flammable Bulk Density : 100-180 kg/m3 Particle size : Sub-micron – 25 micron
