Ardrox® 29 is a diphase product consisting of a highly active acidic lower layer and an insoluble seal which forms an upper layer. It does not contain chlorinated solvents.
Ardrox® 29 is used to remove the more obdurate paint schemes and coatings which are normally resistant to chlorinated based paint removers. It finds particular application in the removal of Kearsley lacquer and stoved silicone epoxy based coatings.

Application :
Components to be stripped are totally immersed at ambient temperature in the lower layer of Ardrox® 29. The type and history of the paint determine the immersion period in the product. Experience has shown that immersion times of ½ - 2 hours are generally suitable.
After immersion, the components are allowed to drain, then rapidly and thoroughly rinsed by immersion in cold running water. The rinse tank must be sited in such a way that carryover of water into the Ardrox® 29 is not possible. A further rinse with high pressure water using an airwater gun is then given to facilitate final removal of the paint scheme. Finally a neutralising dip in 10% v/v Ardrox® 6025A is recommended followed by a further water rinse and drying. Alternatively components may be dried by immersion in an Ardrox® dewatering or protective oil.
