Back-lined sanitary articles, such as bathtubs, shower trays, wash basins and the like, have an acrylic molded part that is reinforced on its rear side with fiberglass-free and asbestos-free polymer material, which is firmly connected to the acrylic molded part, the reinforcement being achieved by curing a polymerisable that is applied to the rear of the molded acrylic glass part , cold-curing, reactive (meth) acrylate system is available, which contains, in addition to other components as polymerizable monomers A): DOLLAR AA) a) (meth) acrylate 30-100% by weight DOLLAR A a1) methyl (meth) acrylate 0 -99.8% by weight DOLLAR A a2) C¶2¶-C¶4¶ (meth) acrylate 0-99.8% by weight DOLLAR A a3)> = C¶5¶ (meth) acrylate 0- 50% by weight DOLLAR A a4) polyvalent (meth) acrylates 0-50% by weight DOLLAR A a5) urethane (meth) acrylates 0.2-50% by weight DOLLAR A b) comonomers 0-70% by weight % DOLLAR A b1) vinyl aromatics 0-35% by weight DOLLAR A b2) vinyl esters 0-35% by weight DOLLAR A where components a1) to a2) are selected so that they are 100% by weight t percent result. DOLLAR A The other components of the (meth) acrylate system are disclosed in the description. The sanitary articles according to the invention meet all the requirements of DIN EN 198 and other relevant standard regulations and are completely and easily recyclable. |
