Abstract
Radiation-curable preparations comprise at least one polymer which has ethylenically unsaturated double bonds and are used for the coating of mineral moldings. A process for coating mineral moldings, and also mineral moldings which have a coating cured by radiation, are also described.
Claims14
A process for preparing a coated mineral molding which comprises at least one mineral binder, the mineral molding having at least one first conventional coating, which comprises as a binder at least one polymer P2 having a glass transition temperature <50.degree. C. which process comprises
- 1) applying a radiation-curable preparation which comprises at least one polymer P1 having ethylenically unsaturated double bonds to the first coating, if appropriate removing the solvent present and
- 2) curing the applied preparation by irradiating with UV radiation or electron beams.
A process as claimed in claim 13, wherein the mineral molding is a freshly produced precast concrete product.
