Backed sanitaryware, such as baths, shower trays, wash basins and the like comprise an acrylic polymer moulding, the reverse of which is reinforced with a polymer material containing neither glass fibre nor asbestos, which material is firmly bonded to the acrylic polymer moulding, wherein the reinforcement is obtainable by curing a polymerisable, cold-curing reactive (meth)acrylate system sprayed onto the reverse of the acrylic polymer moulding, which system contains, in addition to further constituents, A) as polymerisable monomers: A) a) (meth)acrylate 30 - 100 wt.% a1)methyl (meth)acrylate 0 - 99.8 wt.% a2)C2-C4(meth)acrylate 0 - 99.8 wt.% a3)~ C5 (meth)acrylate 0 - 50 wt.% a4)polyfunctional (meth)acrylates 0 - 50 wt.% a5)urethane (meth)acrylates 0.2 - 50 wt.% b) comonomers 0 - 70 wt.% b1)vinyl aromatics 0 - 35 wt.% b2)vinyl esters 0 - 35 wt.% wherein components a1) to b2) are selected such that they amount to 100 wt.%. The further constituents of the (meth)acrylate system are disclosed in the description. The sanitaryware according to the invention meets all requirements of DIN EN 198 and further relevant standards and is completely and straightforwardly recyclable. |
