The influences of materials and environmental factors on the adhesion strength of unsaturated polyester (UP) resin mortar in water have been studied.<br>The adhesion strength was found to be affected mainly by the shrinkage of UP resin at its early stage of hardening. The adhesion strength of conventional UP resin mortar varied widely because of its large shrinkage. It shrinked 0.3-0.4% in length just after the gelation. On the other hand, the low shrinkage UP resin mortar, which contains polyvinyl acetate as the low shrinkage additive and expands 0.2-0.3% in length, showed stable adhesion stregth in water. The effects of other factors such as the joint structure, adhesion interval, pH in water and residual raw materials were also investigated.
