high temperature impact abrasion wearing resistant coating

Packing specification of our BD709 high impact strength anti abrasion wearing resistant repair coating epoxy compound:

1.Common packaging:Packed in a plastic drum, 20Kg/drum, double components,A component:16Kg/drum,B component: 4Kg/drum.
2.We could offer professional customized packaging based on users’ requirements.

Performance feature of our BD709 high temperature wearing abrasion impact resistant repair compound epoxy coating:
1.Two component,black daub shape,can cure at room temperature,heat for curing can get better comprehensive properties.

2.Excellent in wear & corrosion & impact resistance,the wear resistance is 5 times more than PU rubber,20 to 30 times
more than common mixing rubber,the impact resistance is 10 to 15 times more than imported wear resistant protective agent.

3.Can single use,with the better bonding strength to metal substrate through using it together with primer.

4.Can do blade coating,easily forming,construction is convenient,can achieve seamless coverage of equipment overflowing parts.

5.Suitable for the partial repairing and whole protecting of the equipment under the working condition of higher wearing
abrasion resistant,impact resistant requirements.

Product usage:
BD709 high impact anti wearing abrasion repairing epoxy two components coating is the high performance abrasion
wearing resistant,impact resistant polymerization material compounded by high performance wear resistant aggregate
(silicon carbide,alumina,carborundum etc.) and special high polymer material.It can be blade coating,with good water
resistance and high bonding strength,excellent in wearing/abrasion & impact resistance.Used in the wear repairing of
equipment overflowing parts and the preparation of impact & wear resistant coatings on the whole equipment
overflowing parts,exclusively used in the surface wear repairing of magnetic separator roller or the preparation of
abrasion/wear & impact resistant coatings on the roller surface directly,exclusively used in repairing chute,centrifuge
and ball mill end cover.

How to use:
1.Surface treatment:
Do coarsening treatment on the pending-repair part,(sand blasting treatment will get the best effect,if it doesn’t have sand blasting
condition,can do grinding treatment with angle grinder),the surface after coarsening treatment should be cleaned by cleaning agent
(can use acetone,ethyl acetate etc.),then dry it by airing,the surface after this treatment should be the coarsening,clean and fresh
metal substrates.

(Make the special undercoat of BD709 impact & wear resistant coating mix uniformly according to specified percentage,
and brush coating on the substrate surface,then wait for the undercoat curing)

2.The Preparation of BD709 high temperature impact abrasion wearing repair epoxy compound:
After undercoat fully curing,according to the specified ratio,make A and B component of BD709 impact resistant,
abrasion wear resistant coating mix uniformly,and use it up within 30 min.Generally it’s while construction and configuration.
Every time the most configuration quantity is not more than 5Kg,every time configure too much adhesives,the curing speed is fast,
hasn’t been used up until the adhesive has already partial cured and can’t be used.

The suitable coating thickness of BD709 high impact abrasion wearing repair epoxy coating is 3~10mm,make the mixed-up material
be coating on the undercoat surface,the adhesive layer should be compacted.Repair the surface to be smooth after the coating is coated
on the required size.

4.Curing condition:
It can be put into using after suggest curing for 72 hours,if needing instant-on,can heat it up to the temperature of 80 degree slowly
and keep this temperature for about 3 hours after room temperature curing for 4 hours.

Range of application:
Used in the partial repairing and whole protecting under the working condition of the equipment which has higher
wear/abrasion & impact resistant requirements.Such as:power plant coal transportation system transflux part,all coal
washery transflux part,mining transport,separation system etc.Especially suitable for moist or underwater environment,
avoid using in high temperature transportation system.Such as:slurry agitation tank,agitator blade,magnetic separator roller,
belt conveyor roller,centrifuge,vibrating screen girder propping,ball mill end cover,chute,pipeline,elbow etc.

Transportation storage:
1.Sealed storage in the cool and dry place.The warranty period is 12 months.
2.Avoid placing it upside down,knocking against and transporting it as a non-dangerous product during transportation.

Special version:
1.This parameter is for laboratory conditions,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 15 degree,the curing time will prolong,should take proper heating measure.

3.When the environment temperature is more than 25 degree 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.

Fire prevention measures:
Should choose dry powder to extinguish fire,can cover and flap it with dry powder,grit(the construction using abrasive) or
the non chemical fiber fabric when the sizing material catching fire.
