Characteristics:Small viscosity, low-volume hair, stable performance.
Packing:230-250kg / iron drum and 1000kg / assembled barrel. 20-25mt/iso tank.Kept cool place, away from sources of heat.
Use requirements:Adding volume of resin sand about 1.5%, FN-1, FN-2 resin with curing agent for ammonium chloride: urea: water = 1:3:3 solution, other models of resin with sulfonic acid-type curing agent, accounted for 20% of resin volume.
