Finishing performance of nitrocellulose lacquer on oil palm lumber (OPL) / Ummi Fatin Ab Razak

Finishing is the last process of manufacturing furniture but it is important
process that will determine the value of the furniture. The finishing properties of
coating material (nitrocellulose lacquer) on oil palm lumber was ascertained.
The effect of finishing material system with the number of the undercoat and
topcoat layer was determined. There are two system finishing application which
is system A (6 sealer + 3 lacquer) and system B (4 sealer + 4 lacquer).Three
types of finishing testing was used to determined the properties of nitrocellulose
lacquer. There are household test, scratch test and cross-hatch test. This study
used American Society for Testing and Material (ASTM) for the standard testing
and procedures. The result revealed that 6x3 system has good performance in
household test compared to 4x4 system. But, 6x3 and 4x4 system shows no
different in heat resistance and pencil hardness test. This is because of the
properties of oil palm and the characteristic of nitrocellulose lacquer
