The description of BD248 chemical abrasion wear high temperature resistant particle adhesive epoxy coating
performance features of our BD248 high temperature anti abrasion wear resistant particle adhesive coatings:
1.Two component,the paste with super-hard ceramic bead,dark gray.
2.Not need heating,room temperature curing,the temperature resistant can reach to 290 degree.
3.With very high bonding strength to metal substrates.
4.Don’t flow,with good formability,fast curing speed and good operation manufacturability.
5.Suitable for the repairing of wear,corrosion and the preparation of pre-protective wear resistant coating under
high temperature working condition.
product usage of our BD248 heat chemical impact wear abrasion resistant particle coating epoxy adhesives:
BD248 heat chemical abrasion wear resistant epoxy adhesive particle coating is the high performance wear & corrosion resistant
polymerization ceramic coating material compounded by high performance wear resistant ceramic particle and modified toughening
heat resistant resin.Widely used in repairing various high temperature working condition wear-out parts and the preparation of
wear & corrosion resistant coating on the surface of various machine parts which have wear resistant,corrosion resistant requirements
under high temperature working condition.
How to use of our BD248 wear abrasion high temperature resistant epoxy coating particle adhesive:
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 2:1 or volume ratio 2:1,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 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 BD248 is 4～8mm,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 infiltrates fully with the substrates.Repair the surface to be
smooth after the coating is coated in the suitable size,or make the low viscosity wear resistant adhesive be coating on the coating surface.
This material can’t do machining,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,can use iodine tungsten lamp to do
the irradiation heating with 40cm distance from the coating.
