FIELD: ultraviolet-hardened powder compositions based on oligoether(meth)acrylates, possible use for producing lacquer covers on both non heat-resistant (wood, plastic, assembled structures) and metallic substrates, which are used in production of furniture, construction, mechanical engineering and other industrial branches. ^ SUBSTANCE: ultraviolet-hardened powder composition for lacquer covers is described, including film-forming agent component in form of two-component system of oligoether(meth)acrylate and second non-saturated compound with molecular mass equal to 500-970 g/grammolecule, produced by synthesis from p-hydroxyethoxystyrene and diisocyanate, selected from a row: 1,6-hexamethylenediisocyanate, 2,4-toluyelenediisocyanate, isophoronediisocyanate, 4,4'-methylene-(biscyclohexyldiisocyanate) or produced by synthesis from p-hydroxyethoxystyrene, diisocyanate, selected from a row: 1,6-hexamethylenediisocyanate, isophoronediisocyanate, 4,4'-methylene-(biscyclohexyldiisocyanate) and multi-atomic spirits, selected from a row: neopentylglykol, 1,6-hexanediole, while two-component system of film-creating agent contains components in accordance to ratio, appropriate for ratio of non-saturated double links of oligoether(meth)acrylate and non-saturated composition with molecular mass M=500-970 g/grammolecule, within limits from 1:1 to 1:1,2, photo-initiator of benzoyl type, filling agent and degassing agent, with stated ratio of components. ^ EFFECT: suggested ultraviolet-hardened powder composition allows production of lacquer covers with improved properties - increased chemical stability and high level of physical and chemical properties with preservation of decorative and protective properties. ^ 1 cl, 2 tbl, 46 ex |
