Wear Repair Material

Featuring tough abrasion resistant material, WRM® solutions are suitable for a range of high wear, high impact and challenging applications including conveyor belts, roll lagging, scrapers and impellers. Applicable for both inclined and vertical surfaces, these all-in-one, easy to use products ensure a fast return to service, reducing operating downtime.

Wear - Tough abrasion resistant materialRepair - Easy and fast to complete the repairMaterial - Versatile systems to adapt to different substrates

We offer three different WRM® repair kits:

All of these can be used on urethane, rubber, plastic or steel parts.

WRM® Premium offers outstanding physical properties for a longer lifetime in challenging environments.

Step 1: Clean the damaged area. Efficient cleaning of the surface can be achieved by mechanical or/and chemical treatment. For further information, refer to LANXESS “Surface preparation guide”.

Step 2: Apply the primer, if required.LANXESS developed a complete range of primers for different substrates.WRM® Primer Urethane - For Urethane, PVS & RFP substrates. WRM® Primer Metal - For metal substratesWRM® Primer Rubber - For natural and some synthetic rubber substrates

Step 3: Pour part B into part A and mix for 3 minutes - The pourable liquid produced when mixing parts A and B may be used for simple casting jobs Part A must be warmed (oven, hot water bath or direct sunlight). Part B must be stirred before adding it to part A.

Step 4: Add part C only if thixotropic properties are desired.The thixotropic properties allow thick coatings to be applied to vertical surfaces or to the bottom of horizontal structures without slimping or falling off.

Step 5: Apply on the damaged area and leave the material cure WRM® 80T material will completely cure in 24 hours at room temperature, or in 3 hours at 75-90 °C using hot air blowers or heated enclosures. WRM® Premium offers back to service in 2-4 hours.

Always use safety equipment and consult the solvent MSDS.

WRM® is a perfect system to repair highly worn and damaged areas, but also a proven solution to decrease maintenance and replacement costs.

The development of the WRM® line is the result of LANXESS’ deep expertise in the mining market. A typical application that can benefit from WRM® solutions are conveyor belts used in the mining industry. They are one of the most critical pieces of equipment used in mining infrastructure and constantly exposed to high impact and sliding wear.

Other applications are vibratory bowl feed liners, spiral separators, mixers and blades, pump liners, gas scrubbers, concrete mixer barrels, roll lagging, scrapers, impellers, mill lining, lifter bars and discharge shoots.

WRM® offers good chemical and water resistance, very good impact and abrasion resistance compared to harder epoxy repair products. Other properties include better hydrolytic and oil stability, good shock and noise absorption, higher wear and tear resistance, and easy handling with no need for high temperature and pressure for rubber vulcanizing processes. Cost and downtime savings can also be achieved as repairs are carried out on-site.
