Epoxy Pitch Anticorrosive Coating
Summary: It is composed of modified epoxy resin, polyammmide resin, pitch, color filling and auxiliary. DC87-1 is used in priming paint;
DC87-3 is used in anticorrosive face paint;
Product Characteristics:
1. The film is firm and full. The adhesion is strong.
2. It has good functions of resisting chemical medium corrosion, waterproof, resisting microorganism's
eroding.
3. It can be made into thick type paint according to demand.
Usage: It is used in outside wall anticorrosive protection of underground section of oil pipe, fas pipe
and water pipe; anticorrosive paint of underwater facilities and underground facilities. Technical Specification

3. Anticorrosive grade and theory using vollume:Normal anticorrosion:twice priming paint, twice face
paint; using volume:0.8kg/m2; Strengthening anticorrosion: twice priming paint, twice cloth,
three-time face paint; using volume:1.8kg/m2; Key anticorrosion: twice priming paint, three-time
cloth, four-time face paint; using volume:2.5kg/m2;
4. Storage Limit Period:12 months.
