The epoxy coal tar anticorrosive coating is made up of modified epoxy resin, polyamide resin, coal tar pitch, pigments, fillers and auxiliaries.
Coating features: film tough, plump, strong adhesion, with excellent chemical resistance, corrosion resistance, water resistance, anti microbial erosion.
Corrosion protection layer structure: pipeline epoxy coal tar corrosion is the use of two components at room temperature curing type coating, in the steel pipe surface by glass cloth as strengthening coating corrosion. Epoxy coal tar anti-corrosion layer is divided into ordinary grade corrosion protection, strengthening grade corrosion protection (cloth, three oil), special strengthening grade corrosion protection (two cloth, four oil).
Implementation criteria: SY/T0447-96 GB50268-2008
Scope of application: used for buried steel pipeline, water pipeline, sewage pipe and other pipeline anti-corrosion.
