BD248 high temperature wear abrasion resistant coatings

BD248 high temperature abrasion wear resistant ceramic particle paste epoxy coating

Product description:
BD248 high temperature wear abrasion resistant epoxy paste coating is the high performance wear & corrosion resistant polymerization ceramic coating material compounded by high performance wear resistant ceramic particles
and modified toughening heat resistant resin.It’s widely used in repairing of various high temperature working condition wear-out parts and preparation of wear&corrosion resistant coating on the surface of various machine parts which have wear resistant,
corrosion resistant requirements under the high temperature working condition.

product features of our BD248 high temperature chemical abrasion resistant coatings:
1.without heating, curing at the normal temperature,the highest temperature resistance can reach to the temperature
of 290 degree
2.With the high bonding strength to the metal substrates
3.Don’t flow,good form-ability,with a fast curing speed and good operation manufacture-ability
4.Suitable for the repairing of high temperature working condition,wear,corrosion and preparation of
pre-protecting wear resistant 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 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 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.

3.Coating: The suitable coating thickness of BD248 high temperature abrasion wear resistant repair coating is 4-8mm,the most thickness can be 30mm.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 BD427 high temperature
corrosion resistant coating to coat on the material 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.

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 the 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.
