Chemetall 9D4A Dry Powder Developer 10 Lbs.

Ardrox 9D4A dry powder developer is a homogeneous blend of synthetic white powders of fine particle size. It does not contain any mined materials and has very low impurity levels. Ardrox 9D4A is used to develop the complete range of ARDROX fluorescent penetrants. Application of this developer renders any defect indications much easier to see when viewed under ultra-violet light (black light) than conventional powder developers. Ardrox 9D4A offers outstanding advantages in speed of development and resistance to excessive bleed- out of penetrant from defects.
