  The present invention is directed to a coated conduit comprising: a) a conduit having an interior and exterior surface; and b) a cured coating formed from a reaction mixture that is applied to at least one surface of the conduit. The reaction mixture comprises: i) a filler material comprising fibers ranging in length from 0.1 to 15.54 cm and having an aspect ratio of at least 5; and ii) a reactive component that demonstrates a tack-free time of less than five minutes at a temperature of 20 to 25° C. The present invention is also directed to a method of repairing or reinforcing a conduit, comprising: (a) applying a curable coating composition to at least one surface of the conduit, wherein the curable coating composition is formed from the reaction mixture described above; and (b) allowing the curable coating composition to at least partially cure by exposing the composition to ambient conditions.

  本发明涉及一种涂层导管，包括：a) 具有内外表面的导管；b) 由反应混合物形成的固化涂层，该涂层涂覆在导管的至少一个表面上。反应混合物包括：i) 填充材料，由长度为 0.1 至 15.54 厘米、长宽比至少为 5 的纤维组成；ii) 反应组分，在 20 至 25 摄氏度的温度下，无粘性时间小于 5 分钟。本发明还涉及一种修复或加固导管的方法，包括：(a) 将可固化涂层组合物涂在导管的至少一个表面上，其中可固化涂层组合物由上述反应混合物形成；(b) 将可固化涂层组合物暴露在环境条件下，使其至少部分固化。
