POWDER EPOXY-BASED COATING COMPOSITION FOR PIPE COATING WITH EXCELLENT ANTI-CORROSION PROPERTY

摘要

The present invention relates to a powder epoxy resin-based coating composition for pipe coating with excellent anti-corrosion properties which uses an amino alcohol modified epoxy resin as an adhesion improver among basis materials and a coated layer. The powder epoxy resin-based coating composition for pipe coating by the present invention contains 10-80 wt% of epoxy resin, 0.1-50 wt% of the amino alcohol modified epoxy resin, 0.1-30 wt% of a hardener, 0.01-1.0 wt% of a hardening auxiliary agent, 1-50 wt% of an inorganic filler, 1-30 wt% of a metallic filler, and 1-50 wt% of pigment based on the total amount, and provides excellent anti-corrosion properties when the composition is being used for pipe coating.
