Technical characteristics
FIPRO SG 1021 is a highly alkaline powder degreaser used in electroplating for the electrolytic degreasing of ferrous metal surfaces prior to their electrodeposition treatment.
FIPRO SG 1021 consists of a mixture of caustic alkalis, alkaline polyphosphates, sequestering and complexing agents.
Use and Applications
FIPRO SG 1021 should be used in aqueous solution under the following operating conditions:
Treatment time 1’ ÷ 3' in cathodic phase - 30” ÷ 1' in anodic phase
Bath temperature 20 ÷ 45 °C
Bath concentration 50 ÷ 100 g/l
Current density 5 ÷ 10 A/dm2
The optimal operating values will, however, be established by the Fiprokim Technical Service, on a case-by-case basis, during the plant start-up phase, depending on the quality and quantity of foreign substances to be removed present on the surface of the material, the type of material to be treated, and the plant itself.
BATH PREPARATION
To prepare 1000 l of bath, add 50 to 100 kg of FIPRO SG 1021 to the tank filled with water and brought to the operating temperature. Keep the solution under agitation until completely homogenized and proceed to check the bath.

Bath control
Bath control is carried out by determining the total alkalinity, as described below:
take 10 ml of bath using a calibrated pipette, place in a flask, dilute with distilled water and add a few drops of methyl orange indicator. Titrate with 1 N sulfuric (or hydrochloric) acid until the color changes from yellow to red.
The number of ml of 1 N sulfuric (or hydrochloric) acid consumed for the color change gives the total alkalinity of the bath.
A bath prepared at 50 g/l has a point value of approximately 11.5, while one prepared at 100 g/l has a point value of approximately 23.

Power supply
The bath must be checked at least once or twice a day and maintained at the concentration established at start-up. If the point value drops below its initial value, add 4,3 kg of FIPRO SG 1021 to the bath for each missing point and for each 1000 l of bath.
Storage
Keep the degreasing solution free from contaminants; skim or remove by overflow any impurities such as oil or dirt floating on the surface of the bath. Before refilling the tank, remove the deposits formed on the bottom.
