Results
of abrasion tests(Quartant, Prufbau) at a typical water
based overprint varnish (wet film thickness 6 micro
m with a content of a) no wax additive b) 3.15% of a
typical wax emulsion of a competitor c) 2.4% ultrtalube
E-842 N d) 1.4% ULTRALUBE MD-2000 (dosage levels calculated
as solids in the final formulation a) after 200,b,c,
d)after 2000 abrasion cycles

Results
of gloss measurements (micro-tri-gloss,BYK-Gardener)
at the OPV without any addition of wax additive, using
3,15% typical wax emulsion of a competitor, using 2,4%
ULTRALUBE E-842 N and using 1,4% ULTRALUBE MD-2000 (dosage
levels calculated as solids in the final formulation).
