Elastic gas barrier coating compositions

An elastic gas barrier coating composition includes a barrier material dispersed in an aqueous media, a polysulfide, and a curing agent reactive with the polysulfide. When applied to a substrate and cured to form a coating, the barrier material forms a continuous phase, and a polysulfide elastomer forms a discontinuous phase. An elastic gas coating is also disclosed that includes the continuous phase with the barrier material and the discontinuous phase with the polysulfide elastomer. Substrates at least partially coated with elastic gas barrier coating compositions are further disclosed. 弹性气体阻隔涂料组合物包括分散在水性介质中的阻隔材料，多硫化物，和与多硫化物有反应性的固化剂。当施涂到基材上并固化以形成涂层时，阻隔材料形成连续相和多硫化物弹性体形成非连续相。还公开了弹性气体涂层，其包括具有阻隔材料的连续相和具有多硫化物弹性体的非连续相。进步公开了至少部分涂覆有弹性气体阻隔涂料组合物的基材。
