Traditional inorganic putty made with calcium carbonate presents some shortcomings,such as poor water resistance and adhesion.The authors of this paper used latex(16% solids content)and wood flour(500 mesh)to make a wood flour putty to improve the water and adhesion performance.Two different latexes(epoxy resin and isocyanate resin)were used in this study and their effects on the performance of wood-flour putty were evaluated.Performance measurements included paint adhesion,water resistance,wear-resistance,and surface drying time.The results showed that both latexes could improve the performance of wood-flour putty.When the addition of the agents was increased,water resistance and wear resistance were considerably improved.Considering all the performance indexes,the wood-flour putty modified with either 8.0% epoxy resin or 2.0% isocyanate exhibited the best performance.
