SUPER RUSTRIPPER
Highly alkaline compound for Removing Rust, Paint, Phosphate Coatings and Shop Soils from Ferrous Metals
Primary Application
SUPER RUSTRIPPER a versatile alkaline compound, does the work of three materials, a rust stripper, a paint stripper and a detergent. In one operation, it removes rust, many paint finishes, phosphate coatings, as well as forming lubricants, carbon and shop soils. As a result, it replaces acid pickling to eliminate the danger of hydrogen embrittlement and blistering of subsequently applied plated coatings.
It can be applied by tank immersion or spray washing. Super Rustripper meets federal specification TT-C-490C, Method V. It’s also authorized by the USDA for use in federally inspected meat and poultry plants.

Application Procedure:
By Tank Immersion: Recommended concentration is 120 to 600 g/L (1 to 5 Ib/gal) of water from 71 °C (160 °F) to a rolling boil. Immersion time will be determined by the type of soils to be removed.
By Spray Washer: Recommended concentration is 15 to 60 g/L (2 to 8 oz/gal) of water, 71 to 82 °C (160 to 180 °F).
Solution Control
Concentrations are titrated using Gardotest Procedure 92 and Gardotest Procedure 58.
For free and total alkalinity use Gardotest Procedure 123.
For concentrations use Gardotest Procedure 92 or Gardotest Procedure 58. Gardotest Procedure 92:
Sample Size: 1.0 mL
Factor: 10
Gardotest Procedure 58:
Sample Size: 10.0 mL
Factor: 2.5
For free and total alkalinity use Gardotest Procedure 123. (See Procedure)
Equipment:
Chemical Dispensing: The Chemetall Slurry Feed System can be used to premix powdered products with water allowing them to become slurries. The slurries can then be fed into the process automatically with a process controller and/or the proper chemical feed pump. The system includes a slurry tank, tank stand, mixer and chemical feed pump. Please contact the Chemetall Process Equipment and Engineering Department for specific recommendations
Safety and Handling:
Prior to handling and use of BASF Super Rustripper, see the Safety Data Sheet. The SDS should be read and understood by all personnel in contact with the product.
