Product description of our BD707 epoxy wearing compounds:
BD707 small particle wear resistant coating is the high performance wear & corrosion resistant polymerization ceramic material
compounded by high performance wear resistant ceramic particle and modified toughening heat resistant resin.Widely used in the
repairing of various wear-out part and the preparation of wear & corrosion resistant coating on the surface of various machine part
which has wear resistant,corrosion resistant requirements.

Product performance features
1．With very high bonding strength to metal substrates
2．Don’t flow,good form-ability,with fast curing speed and good operation manufacture-ability
3．Suitable for the repairing and protecting of various wear,corrosion working condition.

How to use
1.Surface treatment: Do coarsening treatment on the pending-repair part,grinding with angle grinder or sand blasting etc,the surface after
coarsening treatment should be cleaned,the surface after this treatment should be the one coarsening,dry and fresh substrates,should be no
greasy dirt and dust.

2.Preparation:According to weight ratio or volume ratio 4:1, make A and B two component 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 4Kg,too much adhesive
is solidified too fast,hasn’t been used up until partial adhesive has solidified and can’t be used. According to the actual temperature,
configuration can be properly a little more in winter,proper less in summer.If the temperature is too low,can properly heat up the A
component to reduce viscosity for easy to configure.

3.Coating:The suitable coating thickness of BD707 is 2-8mm,the most thickness can be 30mm.Make the mixed-up material be coating on
the pending-repair part layer by layer,the first layer should be compacted,make it infiltrate fully with the substrates.Repair the surface to be
smooth after the coating is coated in the suitable size.If the surface has high requirements,can make BD426 corrosion resistant repair agent be coating on the surface as the topcoat, this material can’t do machining,should pay attention to controlling the coating thickness to avoid
appearing interference phenomenon in the assembly.

    4.Curing:It(the mixed coating material) can be put into using after curing for 24 hours at room temperature of 25 deg C,the initial/surface
curing time: 1.5 to 2 hours at room temperature 25 deg C,the complete/fully curing time:22-24 hours at room temperature 25 deg C,(If you
can heat the mixing coating materials up to the temperature of 80 to 100 deg C after it initial curing,then keep this temperature for 2 to 3
hours,after that,cool it down to room temperature 25 deg C slowly,in this way,it can improve 30% comprehensive performance of coating materials,the complete/fully curing time is only 6 to 7 hours based on this method) If the temperature is below 10 deg C,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.

Packaging specification
10Kg/group; packed in a plastic drum. A component: 8Kg/drum, B component: 2Kg/drum

Transportation storage
Sealed storage in the cool and dry place. The warranty period is 1 year. 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℃,the curing time will prolong,should take proper heating measure
3.When the environment temperature is more than 25℃ 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.
