colloid stabilized Polyvinyl acetate (PVAc) based wood adhesive has poor
performance in high</span><span><span style=\"font-family:&quot;\">ly</span></span><span><span style=\"font-family:&quot;\"> humid conditions.
Currently, </span></span><span><span style=\"font-family:&quot;\">the </span></span><span><span style=\"font-family:&quot;\">addition of natural fillers
in the wood adhesive is one of the most effective ways to enhance the
performance of PVAc wood adhesive in high</span></span><span><span style=\"font-family:&quot;\">ly</span></span><span><span style=\"font-family:&quot;\"> moist conditions.
Microcrystalline cellulose (MCC) are strong renewable, bio-based material and
ha</span></span><span><span style=\"font-family:&quot;\">s</span></span><span><span style=\"font-family:&quot;\"> great potential in a
reinforcement of the polymeric matrix. Hence, the present work investigates the
applicability of microcrystalline cellulose incorporated</span></span><span><span style=\"font-family:&quot;\"> </span></span><span><span style=\"font-family:&quot;\">3% and 5% in situ emulsion
polymerization PVAc wood adhesives. 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.
Emulsions with different proportion</span></span><span><span style=\"font-family:&quot;\">s</span></span><span><span style=\"font-family:&quot;\"> of MCC were prepared and
the shear strength of the applied adhesive on wood was measured. The viscosity
of the adhesives was increased by increasing the concentration of MCC. The
mechanical properties like tensile strength of adhesives with MCC were measured
by universal tensile machine (UTM). Thermal stability was studied by
differential scanning calorimetry (DSC). The tensile shear strength
demonstrates that MCC can improve bonding strength as compare</span></span><span><span style=\"font-family:&quot;\">d</span></span><span><span style=\"font-family:&quot;\"> to PVAc Homo based adhesive
in </span></span><span><span style=\"font-family:&quot;\">the </span></span><span><span style=\"font-family:&quot;\">wet condition which was
validated through </span></span><span><span style=\"font-family:&quot;\">a </span></span><span><span style=\"font-family:&quot;\">contact angle study. </span></span><span><span style=\"font-family:&quot;\">The </span></span><span><span style=\"font-family:&quot;\">hardness of PVAc films were also changed positively
by the addition of MCC. Here, we studied
