    Abstract: A powdered epoxy coating composition for coating a substrate. The coating composition comprises: (a) from about 50 wt % to about 90 wt % of at least one epoxy resin; (b) from about 1 wt % to about 30 wt % of at least one catechol novolak-type adhesion promoter; and (c) from about 0.1 wt % to about 5 wt % of magnesium oxide. The coating may also include from about 10 wt % to about 48 wt % of an inorganic filler. The coating composition provides improved adhesion at high temperature operating conditions and improved resistance to damage by cathodic disbondment for pipe, rebar, and other substrates.

    Abstract translation: 用于涂覆基材的粉末状环氧涂料组合物。 涂料组合物包含:(a)约50重量%至约90重量%的至少一种环氧树脂; (b)约1重量%至约30重量%的至少一种儿茶酚酚醛清漆型粘合促进剂; 和(c)约0.1重量%至约5重量%的氧化镁。 涂层还可以包括约10重量%至约48重量%的无机填料。 涂料组合物在高温操作条件下提供改进的粘合性,并且通过用于管,钢筋和其它基材的阴极剥离改善耐损伤性。
