The BD407 anti chemical corrosion resistant coatings compounded by various high performance corrosion resistant material and modified toughening resin to give rise to the copolymerization to form the interpenetrating network structure and generate the synergistic effect. In this way, it effectively improves the corrosion resistant performance of the polymers. It’s widely used in the preparation of the corrosion resistant coating on the surface of machine parts of suffering from the corrosion under 100℃or as the undercoat and topcoat of BD408 scale corrosion resistant coating. This product doesn’t contain any organic solvent,and the curing has no any microcosmic pores. it can effectively avoid the medium immersing through solvent evaporation pores to cause under-film corrosion.
How to use:
2.Preparation: According to the mass ratio A:B=4:1, make A and B two components mix uniformly,every time the mixing quantity should not be too much, it’s advisable to ensure that it can be used up within the specific operation time limit every time.
3.Coating:According to the crisscross method，smear the mixed-up materials onto the pending-repair area for 2 times. It is advisable to make the coatings be 0.3-0.6mm thickness.The adhesive layers should be compacted,and make it infiltrate fully with the substrates.For large area protection,you can brush up the coatings for 2~3 times according to the real situation.
4.Curing: it can put into using to cure for 24 hours at the temperature of 25～30℃.It can’t be cured completely,if the temperature is below 15℃, should heat it up (bake with the iodine-tungsten lamp or heat with electric hair dryer) to the temperature of 60～80℃ and keep this temperature for 2 hours to promote the coatings curing fully.
