Abstract: There is a need for additive that enhance the different properties like rheological , tackiness etc. Of the adhesive mix during plywood manufacturing bu using non formaldehyde based adhesive. The present study relates the efficacy study of the natural additive, which is basically fully based on starch and protein available from renewable sources containing a natural tackifier and viscosity enhancer. The adhesive is based predominately on a natural product for example protein, starch based natural material, lignin etc. Thus complementing the use of a lignocelluloses as the primary material. The additive was analysed for physical and chemical properties as per is : 1508 Like PH ash content. Moisture, protein content etc, in order to evaluate the suitability of bond quality and other properties during manufacture of Plywood. 12mm thickness plywood were manufactured with non Formaldehyde adhesive using natural additive at different concentration and evaluated different physical, che3micals properties and board manufacturing condition. Data revels that additive of three to four percent concentration gave satisfactory results in terms or board quality, rheological properties and mechanical properties etc. Five to six percent additive concentration gave excellent result. Addition of higher percent gave unsatisfactory results for manufacturing of ply boards.
Keywords: Additive, starch and protein, natural product, rheological properties and mechanical properties, natural tackifier and viscosity enhancer.
