Underground pipeline anticorrosive paint

Product composition:

The anticorrosive coating of epoxy coal tar is composed of epoxy resin, coal tar pitch, color packing, solvent and curing agent. A, b and b package. Group b from the general curing agent for bottom and surface paint.

Product features:

Underground pipeline anticorrosion coating epoxy coal asphalt coating have excellent rust protection and chemical medium corrosion resistance, good physical and mechanical properties, adhesion, film toughness, wear resistance, water resistance, water resistance, salt fog resistance, hitches in the outer wall of buried pipeline anticorrosion construction around the glass cloth after curing to form similar to the structure of glass fiber reinforced plastic lining, excellent electrical insulation, water permeability, antimicrobial resistance erosion stray current, heat resistance, heat resistance, resistance to shock and other excellent properties.
