BD709 anti impact abrasion resistant protective coatings

Product usage of BD709 high temperature anti impact abrasion wear resistant repair epoxy coating:
BD709 impact resistant wear resistant coating is the high performance wear & 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 wear & 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 wear & impact resistant coatings on
the roller surface directly,exclusively used in repairing chute,centrifuge and ball mill end cover.

Performance feature:
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
wear & impact resistant requirements.

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.Preparation: After undercoat fully curing,according to the specified ratio,make A and B component of BD709 anti impact wear resistant coating mix uniformly,and use it up within 30 min.Generally it’s while construction and preparation.Every time the largest preparation 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.

3.Coating: The suitable coating thickness of BD709 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(the equipment) can be put into using after curing for 24 hours at room temperature of 25 degree,it(the equipment)
can also be put into using after this operation of (BD709 coating) initial curing for 2 hours at room temperature of 25 degree,
then heat it up to the temperature of 100 degree and keep this temperature for 2-3 hours,after that cooling it down to room temperature 25
degree,in this way,it can improve 30% comprehensive performance.If the temperature is below 10 degree,should heat it up or prolong curing
time to promote the curing.General construction in winter,can use iodine tungsten lamp do irradiation heating with 40cm distance from the coating.

Range of application:
Used in the partial repairing and whole protecting under the working condition of the equipment which has
higher wear resistant 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.

Packing specification:
Packed in a plastic drum, 20Kg/drum, two component, A component: 16Kg/drum, B component: 4Kg/drum.

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.
