wood adhesive has poor water and heat resistance. Recently, </span></span></span><span><span><span style=\"font-family:;\" \"=\"\">the </span></span></span><span><span><span style=\"font-family:;\" \"=\"\">addition of fillers in the wood adhesive is one of the most effective
ways to enhance the performance of PVAc wood adhesive. Inorganic fillers have
unique <span>characteristics to improve the
performance of adhesive, such as small size,</span> high surface energy and
surface hardness. Hence, the present work investigates the applicability of
calcium carbonate and clay incorporated 3% in situ emulsion <span>polymerization PVAc wood adhesive. Effect on
physical, thermal and mechanical properties was studied by viscosity, pH,
contact angle measurement, differential scanning calorimetry (DSC) and pencil
hardness test of films.</span> <span>Emulsions
with 3% calcium carbonate and 3% clay were prepared and the shea</span>r
strength of the applied adhesive on wood was measured. The viscosity of the
adhesives was reduced in the</span></span></span><span><span><span style=\"font-family:;\" \"=\"\"> </span></span></span><span><span><span style=\"font-family:;\" \"=\"\">case of
the addition of calcium carbonate <span>and
increased in the case of clay. The mechanical properties like tensile</span> strength of adhesives with calcium carbonate and clay were measured by </span></span></span><span><span><span style=\"font-family:;\" \"=\"\">a </span></span></span><span><span><span style=\"font-family:;\" \"=\"\">universal
tensile machine (UTM). Thermal stability was studied by differential scanning
calorimetry (DSC). The tensile shear strength demonstrates that clay can
