The initial adhesion properties of blends of MF resin and PVAc for adhesion between the fancy veneer and plywood surfaces to manufacture engineered flooring were investigate by the texture analyzer at room temperature by opened assembly time. To determine and compare the effect of PVAc content, compositions of 0, 30, 50, 70 and 100% by weight of MF resin, were used. Because PVAc was room temperature curable water soluble resin, the effect of PVAc was shown in all tack properties and DMTA resuts. From probe tack data, we got the results of the effective tack ranges instead of ‘thumb tack’. Because the process of adhesion in engineered flooring is finished usually in 2-3 minute, the effective tack range was between 100 to 200gf. |
