A Few Details You Need to
Know About Finish Materials
Lacquers (both pre-catalyzed and regular lacquers) and
polyurethanes dry by the evaporation of the solvents in the finish. If a
solvent is reintroduced to the finish after it is dry, the finish will
re-wet and be ruined.
Conversion varnish finishes are a 2 part finish consisting
of a varnish and an acid catalyst that are mixed together immediately prior
to the application. This finish cures through a chemical reaction between
the catalyst and the finish. The reintroduction of a solvent will not
re-wet the finish.
Conversion varnish offers superior clarity, water ,chemical
and abrasion resistance when compared to lacquers and polyurethanes.
Conversion varnish finishes are more difficult to apply,
cost more, and excess finish material must be disposed of as it only has an
8 hour life after catalyzation.
