Abstract:
The invention relates to polyoxymethylene moulded bodies containing at least one polyoxymethylene homopolymer or copolymer A) and optionally other additives B), the surface of said polymer being coated with at least one binding agent C) and a formaldehyde scavenger D). The invention is characterised in that a polyalkylene oxide C1 or a polyvinyl ester C2 or a graft polymer C3 consisting of C1 and C2 or mixtures thereof is used as the binding agent C) and at least one imidazolidine-2-one compound is used as the formaldehyde scavenger D).
Abstract:
The invention relates to a photovoltaic system comprising a plastic carrier and photovoltaic module for installation on roofs. The plastic carrier (1) can be fastened directly on a roof substructure such that an additional roof covering can be dispensed with. The photovoltaic modules can be fastened on the plastic carrier (1) without screwing.
