    • A polymeric article which is subject to attack by oxygen, ozone and/or ultraviolet light is coated with a thin coating of a polymer (10) which is resistant to oxygen, ozone and UV light. It protects the article from cracking or degradation due to any of these causes. The uncoated article serves as a substrate (12). The substrate (12) may be any polymer which is subject to attack by oxygen, ozone and/or ultraviolet light. A preferred coating (14) is cured from a highly saturated polymer having only a small amount of unsaturation, as for example, hydrogenated nitrile rubber (HNBR, or hydrogenated nitrile/butadiene copolymer), highly saturated styrene/butadiene copolymer, hydrogenated polybutadiene, or hydrogenated styrene/vinylpyridine/butadiene terpolymer. The hydrogenated or highly saturated polymer of the coating is obtained by hydrogenating an unsaturated polymer which is a polymer of 1,3-butadiene (5-100 % by weight) and optionally one or more monoethylenically unsaturated polymers (0-95 % by weight). The cured coatings are typically elastomeric. The coating is applied as an uncured highly saturated polymer latex, which is dried and cured in place on the substrate to yield the desired coated article. The thickness of the coating may be about 0.5 mil (0.0005) up to approximately 10 mils (0.01 inch).
    • 经受氧,臭氧和/或紫外线侵蚀的聚合制品涂覆有耐氧,臭氧和紫外线光的聚合物(10)的薄涂层。 它可以保护物品免受由于任何这些原因的破坏或退化。 未涂覆的制品用作基材(12)。 基底(12)可以是被氧气,臭氧和/或紫外线照射的任何聚合物。 优选的涂层(14)由仅具有少量不饱和度的高度饱和的聚合物固化,例如氢化丁腈橡胶(HNBR或氢化腈/丁二烯共聚物),高度饱和的苯乙烯/丁二烯共聚物,氢化聚丁二烯或 氢化苯乙烯/乙烯基吡啶/丁二烯三元共聚物。 通过氢化作为1,3-丁二烯(5-100重量%)的聚合物的不饱和聚合物和任选的一种或多种单烯属不饱和聚合物(0-95重量%)来获得涂层的氢化或高饱和聚合物, 。 固化的涂层通常是弹性体。 将涂层作为未固化的高度饱和的聚合物胶乳施加,将其干燥并固化在基材上的适当位置以产生所需的涂覆制品。 涂层的厚度可以为约0.5密耳(0.0005)至约10密耳(0.01英寸)。
