BR-3TM TROWELABLE URETHANE
| Product Description |
|
BR-3TM is a 100% solids, trowelable putty grade polyurethane material that when mixed in proper portions, will yield a tough rubbery compound with exceptional abrasion and tear resistance. Typical uses for BR-3TM are conveyor parts, belt repair and as a trowelable lining. BR-3TM comes in convenient pre-weighed containers, that when mixed properly, can be applied in any thickness without shrinkage, due to the absence of volatile solvents. The cured repair can be machined or buffed to a smooth finish. |
