used in repairing and protecting high duty coarse particles erosive wear of the pump body,fan shell,pipeline screw conveyor etc.
Product description of BD218 chemical wear abrasion resistant ceramic repair agent epoxy putty compound:
BD218 chemical wearing resistant repair agent epoxy ceramic bead putty compound is the high performance wear & corrosion resistant
polymerization ceramic material compounded by high performance wear abrasion & corrosion resistant material
(such as:ceramic,silicon carbide, silicon carbide, titanium alloy) and modified toughening heat resistant resin.
It’s widely used in repairing and pre-protecting of high duty coarse particles erosive wear of the pump body,fan shell,
pipeline screw conveyor and so on.
How to use of BD218 wearing abrasion chemical resistant ceramic bead epoxy repair putty repairing agent compound:
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 8:1 or volume ratio 4:1, make A and B two components mix uniformly,
and use it up within 30 min. 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.
3.Coating: The suitable coating thickness of BD218 anti wear abrasion epoxy ceramic repair putty compound is 4-8mm.
Make 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 BD406 corrosion resistant repairing agent to coat on the surface of the coating, this material can’t do machining,
so you should pay attention to controlling the coating thickness to avoid appearing interference phenomenon in the assembly.
4.Curing: Cure for 24 hours at the temperature of 25 degree before using.If the temperature is low,should heat it up or prolong
curing time to promote the curing.General construction in winter,you can use iodine tungsten lamp do irradiation heating with 40cm
distance from the coating.
