    • 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.
    • 本发明涉及由包含(A)热塑性塑料的组合物和由其上提供的涂层模塑而成的模塑成型品的用途,该组合物包含选自式(-SiR'R)的聚硅氮烷的组分(B) “-NR”“ - )n,其中R',R”和R“”= -H,或R'和R'“= -H; 和R“” - - 甲基,作为低氢渗透的制品,其中制品相对于氢气在25-30℃的渗透系数优选小于10cm 3 / m 2 d atm,按照 具有DIN 53380-3和ASTM D 3985,并且它们的显微硬度比DIN EN ISO 14577大于150N / mm 2。本发明还涉及具有低氢渗透性的制品,其包括由包含(A)热塑性塑料, 和由其包含选自式(-SiR'R“-NR'”)n的聚硅氮烷的组分(B)的组合物成型的涂层,其中R',R“和R' “= -H,或R'和R'”= -H; 和R'“ - - 甲基。
