The description of BD228 high temperature anti wear abrasion resistant paste epoxy coating adhesives
performance features of our BD228 high temperature abrasion wear resistant paste ceramic coating adhesive:
1.Two component,the paste with superhard ceramic bead,dark gray
2.Not need heating,room temperature curing,the temperature resistant can reach to the temperature of 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 BD228 heat chemical impact wear abrasion resistant paste epoxy compound coating adhesives:
BD248 high temperature chemical abrasion wear impact resistant epoxy ceramic coating adhesive 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 BD228 high temperature chemical corrosion abrasion wear resistant epoxy paste coating 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.
