DOCUMENT TYPE: Patent CA Section: 42 (Coatings, Inks, and Related Products) Resilient polyurethane coatings, useful on floors of sports facilities, contain NCO-contg. urethane prepolymers and mixts. of inorg. fillers and rubber powders treated with polyols and optionally polyamines and/or catalysts. Thus, polypropylene glycol glycerol ether (I) (OH value 56) 50, polypropylene glycol (OH value 56) 50, and TDI 18 parts were heated at 100° for 3 h to give a prepolymer (3.8% NCO). A mixt. 68072-41-3 is the cas registry number. This chemical is also mentioned in this article. of 30 parts powd. waste tire and 70 parts cement was treated with 20 parts I (OH value 56) 20 and 2.0 parts Pb octanoate (20% Pb) for 10 min to give black granules. The prepolymer was mixed with 300 phr granules, cast, and cured at room temp. to give a compn. with Shore A hardness 20 and rebound resilience 31%. .
