BD40272 acid corrosion resistant special epoxy coatings

BD40272 acid corrosion resistant special epoxy coatings
 
 
Product usage:
This product is strong acid resistant macromolecule polymeric material which compounded by modified acid resistant resin and various corrosion resistant materials,used for repair and protection of equipment in strong acid environment.
 
Performance features:
1. High concentration acid corrosion resistance;
2. Free of organic solvents, safe and environmentally friendly;
3. Good adhesion, no shrinkage after curing;
4, anti-flow hanging, convenient construction.
 
Performance index:

Note: the curing conditions of samples (sample blocks) used in all the test data in this note are: 25℃ 24h + 80℃ 4h.
 
How to use:
1. Surface treatment: Clear up the floating dust and stains on the surface of metal substrate,do the roughening treatment for the metal substrate,the surface after treatment should be clean,dry and coarse fresh material surface.
 
2. Preparation: accurately weigh out the right amount of A and B components according to the specified weight ratio on the product label,and stir them thoroughly to mix them evenly.The prepared material 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 harden can’t be used again).
 
3. Coating: make the mixed prepared materials be coating on pending repair parts evenly,and make it be compacted,then make it infiltrate fully with the substrates,it is best to use the cross construction method more than two times,
to be cured before the first layer of coating, then the next layer of construction.Pay attention to the thickness control, the thickness of each layer is controlled at about 0.5mm.
 
4. Curing: It can be put into using after curing 24 hours at room temperature 25℃,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. The above method of use is only a general guiding scheme, please determine the appropriate construction scheme according to the actual conditions on the site before the formal construction
3. When the environment temperature is below 25℃,the required curing time will prolong,should take proper heating measure to expedite the curing speed
4. When the environment temperature is more than 25℃ or the mixing quantity is too large,the curing speed after two components 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.
 
Safety/Health:
This product is a general chemical. Excessive exposure may cause allergic skin diseases. Air circulation should be kept smooth in the construction environment.Wear general work clothes, dustproof mask, protective glasses
and gloves during construction to avoid contact with eyes and skin. In case of accidental contact, rinse with running water repeatedly as soon as possible. If necessary, please seek medical advice immediately.
