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.
