Cellulosic filler material was used to study the effects on poly (Vinyl-acetate) (PVACemulsion wood adhesives. The elastoplastic behaviour of the filler treated PVAC emulsion was studied using differential scanning calorimetry and dynamic mechanical thermal analysis. The result revealed that the glass transition temperature (Tg) of the filler treated polymer is not significantly changed by the addition of the filler materials whereas the tensile modulus, the adhesive hardness, and stiffness were significantly changed. The viscosity of the emulsion and its performance on wood surfaces were greatly affected by fillers. The cellulosic fillers have high oil-absorption capacity, hence increased viscosity to greater extent than the case with Kaolin based filler materials with flash coalescence but of mechanically weaker film. The acidity of the fillers influenced the setting time for wood adhesive bonding. On the whole cellulose filler measured was as effective us the commercial (Kaolin) filler.
