Fusion bonded epoxy coating compositions that include magnesium oxide |
摘要 |
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. |
