BD746 big particle ceramic filling high temperature wearing repair epoxy compound
used in the preparation of wear abrasion corrosion resistant repair coating epoxy compound on the surface of various machine parts which have high temperature,abrasion resistant and corrosion resistant requirements.
BD746 high temperature wear resistant coating is the high performance,high temperature resistant,abrasion & corrosion resistant polymeric
ceramic material which compounded by high performance wear resistant,corrosion resistant material(like ceramic,silicon carbide,carborundum,
titanium alloy etc) and modified toughening heat resistant resin.
Range of application for BD746 big particle ceramic bead filling repair wearing compound high temperature epoxy coating:
Widely used in the preparation of wear & corrosion resistant coatings on the surface of various machine parts which have high temperature,
abrasion resistant and corrosion resistant requirements.The highest temperature resistant is 250 degree,the suggestion using temperature is
1.With excellent wear resistant and corrosion resistant performance
2.With very high bonding strength to the metal substrates
3.Convenient for construction.Don’t drip and slide
4.Suitable for the protection of high temperature corrosion and abrasion working condition.
5.Don’t precipitate and layering.
6.Hot water resistant,steam resistant,acid & alkali resistant.
How to use:
Do the roughing treatment on the pending-repair part,grinding with angle grinder or sand blasting etc.The surface after roughing treatment
should be cleaned,the surface after this treatment should be the one roughen,dry and fresh substrates,should be no greasy dirt and dust.
Make A and B two-component mix uniformly according to the weight ratio A:B=4:1,and use it up within 40 minutes,generally it’s while
construction and configuring adhesives,every time the largest quantity of configuring adhesive is not more than 2 kilograms,too much
adhesive is solidified too fast,hasn’t been used up until the partial adhesive has solidified and can’t be used.According to the actual
temperature,the configuration can be proper some more in winter,and proper some less in summer.If the temperature is too low,
can properly heat up the A component to reduce the viscosity for easy to configure.
The suitable coating thickness of BD746 high temperature abrasion resistant coating is 4-15mm,should make the mixed-up materials be
coating on the pending-repair parts layer by layer,the first layer should be compacted,make it infiltrate fully with the substrates.
Should 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 surface of the coatings.This material can’t do machining,should pay attention to controlling the coating thickness,
in order to avoid appearing the interference phenomenon during the assembly.
It can be put into using based on curing for 24 hours at the temperature of 25 degree,if the temperature is low,should heat it up or prolong
the curing time to promote curing.Generally construction in winter,can use the iodine-tungsten lamp to do the irradiation heating with the 40cm
distance from the coatings.
