Effect of CSI Preservative on the Glue Shear Strength of Plywood Made Using Rubber Wood

Abstract

BACKGROUND & OBJECTIVE: The purpose of the present study was to examine the effect of chitin synthesis
inhibitor (CSI) on glue shear strength of plywood made from rubber wood veneer. METHODOLOGY: Plywood
samples were prepared using Phenol Formaldehyde (PF) resin mixed with lufenuron and diflubenzuron at 0.5, 1 &
2% concentration. Plywood made with this glue was tested for glue shear strength in dry, wet and mycological state
as per Indian Standard. RESULTS: From the results it was found that samples conformed the prescribed values of
glue shear strength as per requisite standard. The study was limited to lab scale for testing the effect of CSI on the
shear strength
