UR-60SLF and UR-90CN belt cover repair systems
Normac offers room-temperature curing polyurethane systems for conveyor belt surface repair and rebuilding. UR-60SLF is a self-levelling formulation for flat, horizontal belt cover repairs such as gouges, scrape damage and top-cover restoration. It is supplied in dual cartridges with static-mix nozzles.
UR-90CN is a two-component, low-viscosity polyurethane for trowel-applied patches and rebuilds. Complete repair kits are available. With the specified preparation and primer, the systems bond to belt rubber, polyurethane and PVC; UR-90CN also lists steel. Product selection and repair timing should follow the current technical data for the substrate and ambient conditions.

Conveyor repair compounds: common questions
How do UR-60SLF and UR-90CN differ?
UR-60SLF is self-levelling and suited to flat, horizontal belt cover repairs. UR-90CN is a two-component system for trowel-applied patches and rebuilds, with a harder cured formulation and steel adhesion listed.
Which belt materials are listed for the Normac systems?
The Normac systems list conveyor belt rubber, polyurethane and PVC when the specified surface preparation and matched primer are used. UR-90CN also lists adhesion to steel.
What affects the time before a repaired belt returns to service?
At 23°C, the published functional cure is approximately one hour for UR-60SLF and one to two hours for UR-90CN, with ultimate cure at 24 hours. Temperature affects curing; use the current technical data for the intended conditions.
