Abstract

Sanitary applicances with a casing, such as bath tubs, shower trays or washbasins, are glass fiber- and asbestos-free, and are further characterized in that the reinforcing material is 1.5 to 10 mm thick and consists of one or two layers. The one layer or the first layer of a multilayered reinforcement is obtained by hardening a first polylmerizable, cole-hardenable, reactive (meth)acrylate system sprayed on the back of the acrylic glass moulding. The (meth)acrylate system contains as filler hollow microparticles, preferably made of plastics, filled with an inert gas. The composition of the (meth)acrylate system is defined by the invention. The disclosed sanitary appliances meet all requirements of the DIN EN 19 norm and can be recycled.
