Barrier coating composition for plastic articles

A barrier layer composition for plastic products contains a metal oxide sol with epoxide or halogen and epoxide groups, a maleic half-ester or half-amide copolymer with fluoro or sulfo groups and a tert. amine catalyst. A barrier layer composition for plastic products, essentially comprising (a) 35-...

Beschreibung
Zusammenfassung:	A barrier layer composition for plastic products contains a metal oxide sol with epoxide or halogen and epoxide groups, a maleic half-ester or half-amide copolymer with fluoro or sulfo groups and a tert. amine catalyst. A barrier layer composition for plastic products, essentially comprising (a) 35-75 wt.% epoxide-containing or halogen- and epoxide-containing metal oxide sol, (b) 20-60 wt.% fluoro- or sulfo-containing maleate half-ester or maleic half-amide copolymer of formula (I) and (c) 0.5-5 wt.% catalyst based on tert. amine(s); M = a vinyl monomer unit; X = oxygen or nitrogen; Y = -(CH2)n-SO3H, -(CH2)n-F or -(CH2)n-H; n = 2-12. Independent claims are also included for (a) a coating solution for the production of a barrier layer for plastic products, containing a composition as above and at least one solvent; (b) plastic products coated with this composition.
