The composition consists of epoxy resin, coal tar, epoxy curing agent, aluminum powder, iron oxide and other anti-rust pigments, physical pigments, Auxiliaries and solvents composed of two components of high-performance anti-rust paint.
846 epoxy asphalt thick slurry anti-rust paint is divided into 846-1 epoxy asphalt thick slurry anti-rust paint and 846-2, 846-3 epoxy asphalt thick slurry anti-rust paint. 846-1, 846-2, 846-3 are a component(also known as the base material), and 846A is a component B(also known as a curing agent).
The main characteristics have excellent water resistance and seawater resistance; Excellent chemical resistance and oil resistance; Good adhesion, impact resistance and wear resistance; Without gas spraying, the thickness of the dry film can reach 125 μm; It has good cathodic protection performance. Excellent anti-rust performance and durability; Recognized by China Classification Society
The application applies to the bottom of the ship, ballast water warehouse, pier steel pile, offshore oil drilling platform, hydraulic steel gate, mine steel support, pipeline internal and external walls, etc. for heavy corrosion resistant coatings.

It is recommended that the number of coatings 846-1 primer, 846-2 or 846-3 paint without spray 1, dry film thickness 250U M, brush or roll coating need to be painted 2-3.
The front track is equipped with paint 702 epoxy zinc workshop primer, 703 epoxy iron workshop primer, 704 inorganic zinc silicate workshop primer, and 842 epoxy cloud iron anti-rust paint. Or direct coating in the derust quality to achieve Sa2. Level 5 steel plate.
When the rear channel is equipped with paint as a rust anti-rust paint on the bottom of the ship, it is necessary to paint the 616 chlorinated rubber ferrite thick plasma anti-rust paint on the 846.
Road, then paint 839 long-acting thick pulp anti-fouling paint.
846 epoxy asphalt thick slurry rust resistant paint can be used separately in the application without marine pollution.
Surface treatment has oxide-coated steel: sandblasting treatment to Sa2. Level 5; Non-oxide leather steel: sandblasting treatment to Sa 2.5, or grinding with elastic grinding wheel to St 3; Covered with shop primer steel: using light sandblasting or elastic grinding wheel plate at rust to St 3; Welding, flame cutting or pyrotechnical correction of burned parts: remove slag, spatter, polished and smooth, polished with elastic grinding wheel to St 3
The temperature of the substrate under construction conditions must be higher than 3 °C above the dew point; When the temperature of the substrate is below 5 °C, the reaction between the epoxy and the curing agent stops, and it is not suitable for construction. Winter anti-rust paint can be used for painting. Relative humidity not more than 85 %
