The changing rules for contact angles of four kinds of adhesives were studied in the paper.The result shows that the wetness of all adhesives on the surface of Moso bamboo was less than that of Chinese fir,and the wetness on the knot position of bamboo was less than that on the inner layers.On the surfaces of a same Moso bamboo or Chinese fir,the wetness of PMDI was the best,that of EPI was the worst,and that of PF or UF were between that of PMDI and EPI.Through calculating the coefficients of penetration and diffusion,the wetness of adhesives on the surfaces of Moso bamboo and Chinese fir were evaluated.
