本SAE信息报告涵盖了树脂基材料的薄涂层，可在径向唇形轴密封件的金属外径上涂覆，以在配合孔表面过于粗糙而无法确保正确密封时（通常在表面光洁度超过2.54 gm rda时，或在加压应用中）提供密封。涂层应具有以下特征:a.）材料应干燥成坚韧、柔软、无粘性的薄膜；b、 ）厚度通常在0.005至0.076 mm之间；c、 ）刮擦时不应出现裂纹、剥落或粉末；d、 ）如注所示，涂层应粘附在密封件上；和e.）在待密封介质中测试时，密封剂不得显示任何剥落、起泡、软化或溶解的迹象。

This SAE Information Report covers thin coatings of resinous based materials that can be placed on the metallic outer diameter of radial lip-type shaft seals to provide sealing when the mating bore finish is too rough to insure a proper seal (typically when finish exceeds 2.54 \gm r\da, or in pressurized applications).The coatings will have the following characteristics: a.) material shall dry to a tough, flexible, and non-tacky film; b.) thickness typically ranges from 0.005 to 0.076 mm; c.) It shall not crack, flake or powder when scraped; d.) Coating shall adhere to seal case as noted in text; and e.) The sealer shall not show any evidence of peeling, blistering, softening or dissolution when tested in media to be sealed.
