 Will shrinkage occur with ART-resin? No, shrinkage will not occur with ART-resin. Shrinkage occurs because of solvents or non-reactive diluents or cheap fillers in the makeup of the formulation. Those are the materials that come up out of the product and are released as VOCs during the curing process. ART-resin has no solvents, no non-reactive diluents, no cheap filler. So shrinkage is not an issue.
