ABSTRACT:
The invention provides rolls, belts and other biasable members having at least one layer or coating of an elastomeric resilient polyurethane formed by reacting (a) a polyisocyanate prepolymer comprising the reaction product of a saturated aliphatic polyisocyanate, a saturated cycloaliphatic polisocyanate, or an aromatic polyisocyanate and a polyol free of aliphatic unsaturation, preferably a polyalkylene glycol in which the alkylene group contains 2 to 8 carbon atoms, and (b) a hardening mixture comprising a polyol of (a) or a diamine free of aliphatic unsaturation, or a mixture thereof and, as a conductivity control agent, from 0.001 to 5.0 weight percent, based on the total weight of (b), of a complex of ethylene glycol or an oligoethylene glycol selected from the group consisting of di-, tri- and tetraethylene glycol with an ionizable antimony halide salt selected from the group consisting of antimony trifluoride, antimony trichloride, antimony tribromide and antimony triiodide.
The resistivity of the elastomeric resilient polyurethane coating on the biasable member is controlled or adjusted to within a desired level of resistivity due to the inclusion of the conductivity control agent in the polyurethane elastomer. Additionally, the inclusion of the conductivity control agent in the polyurethane elastomer reduces the sensitivity of the resistivity of the polyurethane coating on the biasable member to changes in relative humidity.
