| Summary: | Tests to determine the quality of finish of nitrocellulose and acid catalysed lacquer with and without
sanding between coatings were conducted on four fast growing
species , namely : batai , yamane , acacia , and rubberwood.
The quality of finishes was evaluated in terms of
machining ability , surface performace , surface gloss , adhesion
ability , hardness , and flexibility of wood finish . The testing
methods were based on The British Standard No . 3962 part 6 ,
1980 and Draft of Malaysian Standard part 1 ,1987 .
The results indicated that on rubberwood , acacia, batai
and yamane nitrocellulose lacquer had higher gloss and was
more flexible than acid catalysed lacquer with and without
sanding in between coatings.On the other hand , acid
catalysed lacquer had greater hardness and higher adhesion
ability than nitrocellulose lacquer with and without sanding
in between coatings for all species.
In general the quality of nitrocellulose lacquer and acid
catalysed lacquer on rubberwood was the highest , followed by
acacia, yamane , and batai . Moreover , these species have a
good machining ability and have a good surface performance ,
and the results showed rubberwood , acacia and yamane to be
suitable for furniture. |
