          Construction parameters

                        Volume solids 69 3% (measured according to ISO / IEC 3233: 1998) (after mixing)

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

                        The dry film thickness was 250 m

                        The wet film thickness was 362 m

                        The theoretical amount of 470g / m2

                                       Group B 22

          Curing time (after mixing) (20 C) 30 min

          Pot life (after mixing) (20 ) 8h

          (When the temperature is above 30 , the pot life of the mixture of A and B will be shortened with the increase of temperature)

          Drying time

          Hard work




          * Fully cured




          * Less than 5 due to curing reaction stopped, not construction

          The shortest








          It is recommended that the number of coating channels be sprayed 1-2 times without air and the dry film thickness is 250m.

          702 epoxy zinc-rich shop primer, 703 epoxy zinc oxide shop primer, 704 inorganic zinc silicate shop primer, 842 epoxy cloud iron antirust paint, or direct painting in the derusting quality to achieve Sa2.5 steel surface.

          After the road supporting the paint as the bottom anti-rust paint, the 546 should be painted on the 616 chlorinated rubber iron red thick slurry antirust paint as a transitional layer, and then coating 839 long-lasting thick slurry antifouling paint to Increase the interlayer adhesion of the paint film. 546 can be used alone in marine biofouling applications.

          Surface treatment

                        * There are oxide steel: sandblasting to Sa2.5 level

                        No oxide steel: sandblasted to Sa2.5 level, or to the abrasive wheel grinding to St3 level

                        Steel coated with shop primer: sandblasted or sanded with a flexible grinding wheel to the St3 level

                        Welding, flame cutting or fire work correction Burned parts: remove welding slag, splash, polished smooth, with elastic grinding wheel to St3 level

          Construction conditions

                        • Substrate temperature should be above 3 above dew point

                        When the temperature of the substrate is lower than 5 , the reaction between epoxy and curing agent is stopped, and it is not suitable for outdoor construction. The epoxy asphalt antirust paint
