BD226 wear resistant ceramic small particle paste epoxy coating adhesives

Product description of BD226 small ceramic bead particle adhesive wearing compound
epoxy coating:
BD226 wear resistant ceramic particle coating adhesive is the high performance wear & corrosion resistant polymerization
ceramic material compounded by high performance wear resistant material(Metal carbides,small particles spherical ceramic, etc)
and modified toughening heat resistant resin.It’s widely used in repairing of various wear out parts from general load fine particle erosion wear and preparation of wear&corrosion resistant coating on the surface of
various machine parts which have wear resistant ,corrosion resistant requirements.

product features of BD226 abrasion resistant particle adhesives epoxy compound small particle
ceramic coating:
1.With the high bonding strength to the metal substrates
2.don’t flow,good form-ability,with a fast curing speed and good operation manufacture-ability
3. Suitable for the large area repairing of fine particle wear-out equipment and preparation of pre-protecting coating

How to use
1.Surface treatment: Do coarsening treatment on the pending-repair area, grinding with angle grinder or sand blasting and so on, 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 3.5:1 or volume ratio 3:1, make A and B two components 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
1.5Kg, too much adhesive 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 appropriately a little more in winter,proper less in summer.
If the temperature is too low,you can properly heat up the A component to reduce viscosity for easy to configure.

Coating: The suitable coating thickness of BD226 abrasion resistant ceramic beads small particles paste epoxy coating is 2～8mm.
Make the mixed-up material spread coating on the pending-repair area 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 spreading in the suitable size,or use low viscosity wear resistant adhesive to coat on the coating surface.
This material can’t do machining,so you should pay attention to controlling the coating thickness to avoid appearing interference
phenomenon in the assembly.

Curing: Cure for 24 hours at the temperature of 25 degree before using,If the temperature is low,should heat it up or prolong the 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
1.Two-component,10Kg/group; packed in a plastic drum.A component : 7.78Kg/drum, B component : 2.22Kg/drum.
2.We could offer you professional customized packaging or subpackage services based on users' requirements.

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 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.
