Dimensional Stability of Fast Growing Teak and Jabon Woods by Chemical Densification

In general, wood from plantation forests are dimensionally unstable, therefore, timber use are limited. This paper sobserves dimensional stability of chemically densified fast-growing teak (JCT) and jabon woods. JCT and jabon woods were impregnated using a mixture of old teak sawdust extracts and resin. The resin used were vinyl acrylic and polyvinyl acetate in three concentrations : 8, 10, and 12% (w/v),and two compositions of resorcinol resin. Results show that in general, dimensions of the impregnated wood are more stable than non-impregnated wood.Wood impregnated with the mixture of teak extract solution and resorcinol resin shows better dimentional stability than other resins.
