BD7045G slurry recycle pump special high strength anti abrasion wearing resistant repair compound epoxy resin coatings
Product usage:
This product the high performance abrasion resistant,corrosion resistant material which
compounded by NDI-PTMG modified epoxy resin and abrasion wearing resistant aggregate from the core technology of Xiangyang City Hundred Shield Coating Material Co.,Ltd.Used in repairing the mining use slurry pump which
suffers from serious erosive wear,the restored life of repairing workpiece full size generally can reach to new workpiece service life.
Performance features:
1. Good toughness,excellent impact resistance,with very high bonding strength to metal substrate.
2. Don’t flow,don’t drip,easy to shape up.The curing speed is moderate and the operation technology is good.
3. Acid resistant,alkali resistant,hot water resistant,suitable for repairing and protecting of various wear working conditions.

How to use:
1. Surface treatment: clear up the pending-repair parts,expose the fresh substrate,do the roughing treatment for the fresh substrate,the treated surface should be a dry, rough, clean and fresh surface.
2. Brush coating the prime coat: make A and B two components of special prime coat mix uniformly according to the specified weight ratio,and brush coating on treated metal substrate surface.
3. The preparation of BD7045G abrasion resistant coatings:accurately weigh out the right amount of A and B components according to the specified weight ratio,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 hard can’t be used again).
4. Coating: apply the mixed material onto the uncured prime coat and press it compacted,make it infiltrate fully with the substrates,the suitable coating thickness is 2mm to 10mm,the largest thickness can be 20mm for each layer,
If the workpiece design requires a thickness of more than 20mm,layered coating should be adopted for construction,The surface layer should be repaired flat after the repair to the required size,this material can’t do machining,should pay
attention to controlling the coating thickness to avoid appearing interference phenomenon in the assembly.
5. Curing:it can be put into light load using after curing 24 hours at room temperature 25¡æ,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,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 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.
