UBE Urethane Systems offer a complete line of on-site repair kits for damaged equipment. Our WRM® and WRM® Premium wear repair material solutions help decrease maintenance costs for the on-site repair of rubber, urethane, plastic and metal components.
"All-in-one" Repair Kit
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 material Repair - Easy and fast to complete the repair Material - Versatile systems to adapt to different substrates
We offer three different WRM® repair kits:
WRM® 80T
WRM® Premium 80T
WRM® Premium 65T
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.
Improved sliding wear resistance
Up to double abrasion resistance due to higher rebound
Excellent property retention in hot, wet, acid and alkaline environments
WRM® application in a few easy steps
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 UBE Urethane Systems "Surface preparation guide". Step 2:Apply the primer, if required.
UBE Urethane Systems developed a complete range of primers for different substrates.
WRM® Primer Urethane - For Urethane, PVS & RFP substrates.
WRM® Primer Metal - For metal substrates
WRM® 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.

Applications
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 UBE Urethane Systems' 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.
Success Story
Spiral Separator
The spiral separators, made of epoxy and fiberglass, allow gravity separation techniques. The surface of the spiral separator is constantly submitted to abrasive mineral slurries, resulting in surface damage and therefore flow changes. Any change in the spiral profile reduces yield and profits.
A new spiral part costs over USD 10.000 and its lifetime is ~18-24 months. The WRM® repair kit allows 80% savings on new equipment as WRM® can double the spirals lifetime. The costs to repair are approximately USD 3.000 including material costs and manpower. A spiral repairedwith WRM® can extend the lifetime, similar to that of a new part.
In addition to cost saving on new parts, another benefit is delivery time. The delivery time of new equipment can be about 4-6 months, while repairing the part with WRM® is much quicker and decreases production downtime.
