WearShield Impact Resistant Epoxy Paste
WearShield is an impact resistant epoxy paste heavily filled with alumina beads which protects equipment, machinery and surfaces subjected to intense processes. It is applied to metal, wood and most plastics to form an alumina-reinforced, hardened shell up to 6mm thick.
The dense alumina bead structure and high resin content of WearShield enable it to offer ultimate resistance against all types of impact in the most abrasive of environments.
It was originally formulated for the tough requirements of the South America mining industry with expansion since into power plants, quarries and mills. It protects a diverse range of processing and plant equipment including ash handling systems, scrubbers, silos, chutes and metal castings.
WearShield also repairs heavy damage and rebuilds existing systems already suffering from impact damage by creating a new, hardened surface. As well as impact, it protects against wear, abrasion, corrosion and chemical attack.
Depending on the amount of epoxy paste being mixed and ambient temperatures, WearShield has a work time of between 30 and 60 minutes. This enables significant amounts to be mixed and applied without the threat of premature curing, even at higher ambient temperatures.
WearShield sets to a dark grey colour and the alumina beads are visible in the cured material. Once cured, WearShield can be top coated with Ceramic Brushable Blue Epoxy Coating to create an ultra-smooth repair, further reducing abrasion damage and making clean up more effective.
WearShield Impact Resistant Epoxy Paste Details
Before applying WearShield, surfaces should be free of paint, rust and grime. The substrate should then be roughened up through either grit blasting or grinding with a coarse wheel or abrasive disk pad.
Full instructions detailing the preparation process can be found on the Technical Data Sheet and are provided with the product.
WearShield should be applied as soon as the preparation procedure is completed. Part A and Part B are mixed together at a 2:1 ratio by weight or volume until streak free and uniform in colour. For convenience when mixing the entire Kit, each WearShield part is supplied in the correct 2:1 ratio.
The epoxy paste is then spread over the area requiring protection using a putty knife. WearShield should be pushed in firmly to ensure maximum contact and to avoid trapping air between the paste and the surface.
WearShield is built up until the desired thickness is achieved, recommended to be at least 6mm. The recoat time of WearShield is four hours.
A functional cure is achieved in between eight and 12 hours and a full cure in 24 hours. WearShield is temperature resistant to 120°C and is thixotropic, meaning it will not sag. The light consistency makes it easier to mix than stiff and heavy traditional epoxy pastes.
For a faster working impact resistant epoxy paste filled with alumina beads, please see WearShield Rapid. It comes with a 5-minute work time, a 45-minute functional cure and a three-hour full cure. WearShield Rapid reduces disruption and downtime by allowing equipment to be put back into use more quickly.

How to increase wear resistance with WearShield Impact Resistant Epoxy
See how WearShield increases impact and wear resistance by creating an alumina reinforced protective layer over equipment, machinery, parts and surfaces. This demonstration involved the application process of WearShield to a demo piece, an abrasion and impact test, followed by overcoating with Ceramic Brushable Blue to provide an ultra-smooth layer to the repair.
