Description :

　　Composition: A two-component epoxy asphalt coating composed of epoxy resin, coal tar pitch, pigments, additives, solvents, etc

　　Main features:

　　Has excellent water resistance and salt water resistance;

　　Has good oil resistance and chemical resistance performance;

　　The tough paint film has excellent physical properties such as adhesion, wear resistance, and impact resistance;

　　Has good rust resistance and durability;

　　Resistant to microbial corrosion and excellent electrical insulation

　　Purpose:

　　Suitable for use as external anti-corrosion coating and pipeline joint anti-corrosion coating for oil transportation pipelines, tap water pipelines, and cooling water pipelines in power plants and industrial and mining enterprises. It can also be used as internal anti rust coating for cooling water pipelines in power plants or industrial and mining enterprises.

　　Color: Dark Brown, Black

　　Basic parameters: Density of 1.5cm2 per month

　　Dry film thickness: 70um

　　Wet film thickness: 130um

　　Drying time:

　　Proportion: Component A: Component B=10:1 (weight ratio)

　　Interval between coats: 24 hours at 25 ℃

　　Suggested number of pipelines to be painted: anti-corrosion coating layer for the outer wall or joint of the pipeline (1), two cloth and three paint coating layer (ordinary anti-corrosion structure), and two layers of glass cloth wrapped between the coatings

　　Painting sequence: Primer - Topcoat - Glass Cloth - Topcoat - Glass Wall - Topcoat with a total thickness of 500-800um. 2. Anti corrosion coating on the inner wall of the pipeline, surface treatment, and coating of steel with oxide skin should reach a thickness of 310um or above. Steel: sandblasted to Sa2.5 level or manually derusted to St3 level. Base material temperature: oxygen free steel; Sandblasting treatment to Sa2.5 level; Or use pneumatic or electric elastic grinding wheels to polish to St3 coated workshop.

　　Primer steel: The damaged, corroded, and white areas of the paint film must undergo secondary rust removal and be polished to St3. The substrate temperature must be 3 ℃ above the dew point.
