Disperse the "Carbopol" resin in the water. Add the sodium hydroxide solution. Add the gluconic acid solutionn. Stir until all the gluconic acid dissolves.
Note: This remover is easily and neatly brushed on any metal surface.
Depending on the thickness of rust, the solution should stand for 1-10 min before being rinsed off. For light films a minute is sufficient.
Eye and skin contact is to be avoided due to high alkalinity. There are no fumes or odors. Any residue on equipment or tools can be removed with water.
Only the rust is removed by the solution, the metal is left clean, bare, and unaffected.
The solution is excellent for applications where any change in dimensions must be kept to a minimum. |
