Key Attributes

SCHWEGO corrit 6831 is used to compensate poor preparation of the substrate and unsatisfactory painting conditions: Manual derusting (residues of rust / flash rust) Unfavorable weather conditions, e.g. damp surfaces Careless preparation of the substrate e.g. traces of grease Difficulties caused by type of construction or location, e.g. rest rust SCHWEGO corrit 6831 converts residual rust into a non-corroding iron organic compound and provides long term protection against corrosion. The wetting additive contained in SCHWEGO corrit 6831 ensures good penetration of the residual rust particles, dirt and wetting of badly degreased surfaces, thus adhesion is promoted.

Processing Information

The optimum dosage of SCHWEGO corrit 6831 is 3.0 - 5.0 %, calculated on total formulation. SCHWEGO corrit 6831 should added before dispersion of the pigments. Post addition is possible, if SCHWEGO corrit 6831 is homogeneously distributed. SCHWEGO corrit 6831 should be added slowly and carefully while mixing in order to avoid local overdosage. Before adding, predilution in one of the solvents of the formulation is useful, for instance water or glycol.To test the activity of SCHWEGO corrit 6831 it is necessary to use pre-rusted test panels and to carry out accelerated weathering. The salt spray test does not correlate with outdoor weathering and should not be used.SCHWEGO corrit 6831 does not lead to yellowing or langer drying times. Delays in drying time may occur if excessive doses are used. A slight discolouration may be possible and has no influence on the effectiveness of the product. The use of SCHWEGO corrit 6831 in pastel colored paints should be tested beforehand.
