BD40267 high temperature corrosion resistant epoxy coatings

BD40267 high temperature corrosion resistant epoxy resin coatings (Special for bag dust collecting device)
 
Product usage:
This product is the special protective coating material developed by our company for the anti-corrosion protection of the bag dust collecting equipment. It has high bonding strength with the base material,
strong anti-permeability ability, and can withstand high temperature ammonia gas corrosion for a long time.Temperature resistance up to 250℃, can work in the environment below 220℃ for a long time.
 
Performance features:
1. No organic solvent, which can improve the anti-permeability ability and is safe and environmentally friendly;
2. Good adhesion, high mechanical strength, no shrinkage after curing;
3. It can be cured at room temperature, with low environmental requirements and convenient construction;
4, can brush coating, roller coating, spraying coating, easy to receive light, anti-sagging, good operation technology.
 
Physical and chemical parameters:

Note: the curing conditions of samples (sample blocks) used in all the test data in this note are: 25℃ 24h + 100℃ 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 A:B = 8:1,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,make it infiltrate fully with the substrates.For large area protection,the decussation coating method can be used for 2 ~ 3 times
according to the situation, and the thickness of each layer should be controlled within 0.3-0.5mm.
 
4. Curing: It can be put into using under the light load 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.
 
5. Detection of leakage points: In large area construction, leakage points shall be checked by spark leak detector after the coating is completely cured. Repair shall be carried out after the leakage points are found.When repairing,
the angle mill should be used to enlarge the leak point and expose the base material, and then take appropriate amount of coating material for repairing according to 2 ~ 4 steps.After the repair point curing,check the leakage point
to ensure that there is no leakage point of the coating before the equipment is put into use.
 
6. Thickness detection: The film thickness meter should be used to measure whether the coating reaches the expected thickness during large-area construction. If it is not up to the standard, the coating should be applied again in
steps 1-5 until it reaches the standard.
 
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℃,the required curing time will prolong,should take proper heating measure to expedite the curing speed
3.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.
 
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.
