Ardrox 29 Immersion Paint & Coating Remover 12.5Lt Pail *OMAT 1/56A

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.

Features

• 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 whicha are normally resistant to chlorinated based paint removers.
• It finds particular application in removal of Kearsley lacquer and stoved silicone epoxy based coatings.

Applications:

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 ° - 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 air- water 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.

It is not possible to replenish the active, lower layer of Ardrox 29. When the efficiency of the paint removal becomes too low, the tank should be disposed of and remade with fresh chemical. The thickness of the upper layer should be maintained with Ardrox 29 Seal at a level of 5-10 cm in order to prevent water from the atmosphere from being absorbed by the lower phase (which would lead to a significant increase in the corrosivity of the lower layer towards all substrates).A convenient way of measuring the depth of both layers is by immersing a glass test-tube, or similar, into the bath and observing the thickness of the clear upper layer.
