BD4081 glass flake repairing compound anti corrosion resistant epoxy coatings:
Product usage:
This product is two components corrosion resistant material produced by copolymerization reaction of various high performance anti corrosion materials and modified toughening resin.The glass flake corrosion resistant coating mainly
made of vinyl resin has a higher bonding strength.It is mainly used for repairing damaged parts of the flake anti corrosive coating which used in desulfurization system of thermal power plant.
Performance features:
1, excellent corrosion resistance, can withstand a variety of medium erosion;
2, good toughness,the bonding strength is much higher than the flake corrosion resistant coating itself.

How to use:
1. Surface treatment: clear up the pending-repair parts,do the roughing treatment for the pending repair surface,then remove the floating dust and oil stain from the surface by cleaning agent,dry it by airing.
2. The preparation: accurately weigh out the right amount of A and B components according to the mixing weight ratio A:B = 4:1,and stir them thoroughly to mix them evenly.The mixed prepared materials should be used up
within the specified operating time limit.(that is,before the material starts to become sticky, and the material after becoming sticky and hard can’t be used again)
3. Coating:make the mixed prepared materials be coating on pending repair parts and press it compacted,make it infiltrate fully with the substrates,apply to a suitable size and flatten the surface with a plastic scraper.
4. Curing:It can be put into light load using after curing for 24 hours at room temperature 25 deg C,when the construction ambient temperature is too low,heating or prolonging curing time should be used to complete the curing.
Special version:
1.The product parameter is obtained for laboratory testing,only for reference,due to the actual working condition is more complex,suggest the users to do the pretest according to actual working condition.
2.When the environment temperature is below 25¡æ,the curing time will prolong,if you want to expedite the curing speed, should take proper heating measure
3.When the environment temperature is more than 25¡æ or the mixing quantity is too large,the curing speed after mixing will expedite,should properly shorten the application time of coating after mixing.
Construction protective measures:
1.Wear the protective masks,wear the protective glasses and rubber gloves
2.Need washing hands with soap before eating,drinking or smoking.
3.The health hazard after touching: a few people will have skin allergy phenomenon,see a doctor in time and avoid touching with this product again.should wipe it with ethyl acetate when the sizing material paste on the skin by careless,
then wash it with clear water.Should wash it with clear water immediately and see a doctor when splashing into the eyes by careless.
Warm Prompt:
Residual adhesive solution cured products are non-toxic harmless organic solid,but maybe it will produce poisonous gas when burning,non-professional personnel can not do combustion disposal,should be sent to garbage power
plant or garbage burning place treatment.
