Dimensional stability properties of laminated veneer lumber made from oil palm trunk bonded with different cold set adhesives / Siti Noorbaini Sarmin, Othman Sulaiman and Rokiah Hashim

Dimensional stability properties of laminated veneer lumber (LVL) from oil palm trunk (OPT) bonded with three different cold set adhesives namely emulsion polymer isocyanate (I, 3-butadiene-styrene and vinyl acetate based) and polyvinyl acetate were investigated. Three-ply experimental LVL from OP...
