The invention relates to use of a molding molded from a composition encompassing (A) a thermoplastic, and a coating provided thereon, molded from a composition encompassing a component (B) which has been selected from a polysilazane of the formula (—SiR′R″—NR′″-)n, where either R′, R″ and R′″=—H, or R′ and R′″=—H; and R′″=-methyl, as articles with low hydrogen permeation, where the permeation coefficient of the article with respect to hydrogen gas at from 25 to 30° C. is preferably smaller than 10 cm3 mm/m2 d atm, measured in accordance with DIN 53380-3 and ASTM D 3985, and their microhardness is greater than 150 N/mm2 to DIN EN ISO 14577. The invention further relates to articles with low hydrogen permeation encompassing a molding molded from a composition encompassing (A) a thermoplastic, and a coating provided thereon, molded from a composition encompassing a component (B) which has been selected from a polysilazane of the formula (—SiR′R″—NR′″-)n, where either R′, R″ and R′″=—H, or R′ and R′″=—H; and R′″=-methyl. |
