Ardrox 9d4a

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 UV-A / 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.
