Abstract
A reactive resin compositions include at least one polymerizable system, at least one volatile organic compound, cyclodextrin, and optionally at least one curing agent, which are obtainable by mixing the polymerizable system with the volatile organic compound and the cyclodextrin and storing the mixture for a period of time until an equilibrium is established between the volatile organic compound and the cyclodextrin. By adding cyclodextrin it is possible to reduce the VOC emissions of corresponding reactive resin compositions significantly, the observed effect being greater than would be expected on the basis of the molar ratio of the volatile organic compound to the cyclodextrin. The reactive resin composition can thus be used advantageously in applications such as coatings and/or sealants, in which the evaporation of organic compounds should be avoided.
