Abstract
The purpose of this study was to evaluate the feasibility
of using highly filled powders with 100 parts per weight
of calcium carbonate and 10 parts per weight of polymer,
acting as binder, as electrostatically applied paper
coatings. Such powders prepared by different methods were
evaluated as being suitable for electrostatic coating.
Powders compacted at elevated temperatures demonstrated
cohesion superior to that of calcium carbonate, and at
best similar to that of aqueous coatings. Cohesion,
porosity and thus absorption properties of compacted
powders were affected by the powder preparation method,
compaction process, and powder composition. Powders
containing semicrystalline polymer turned out to be the
most interesting for further testing.
