The objective of this study was to find an appropriate method of evaluating mold-releasability ofmold-releasingagents for polyester resin concrete. A tension or shearing test involving resin concrete cast in thin frames on steel plates coated with mold-releasing agents was selected as an appropriate method. BY apply- ing this method, 17 commercially available mold-releasing agents were tested and evaluated for mold-releasability. The effect of vibrating compaction on the mold-releasability was also examined. It is concluded from the results that the mold-releasability of silicone and fluorine-containing agents is excellent, and that generally it is considerably affected by vibrating compaction.
