| 20090005492 | AMBIENT TEMPERATURE CURABLE SURFACE FINISHING MATERIALS FOR INDOOR AND OUTDOOR FACILITIES - An excellent surface finishing material for indoor and outdoor facilities which ensures a given usable operating time and suppressed adhesion of the surface after curing is produced by reacting an A-side composed mainly of a urethane prepolymer having terminal isocyanate groups and a B-side composed mainly of a polyol containing a crosslinker and a filler. The prepolymer is the reaction product of a polyisocyanate composed of at least 50% by weight 2,4′-MI with a polyol. The filler contains an acid filler having a pH of less than 7. | 01-01-2009 |
| 20090018256 | POLYURETHANE AND POLYURETHANE UREA ELASTOMERS BASED ON POLYCARBONATE POLYOLS - The present invention relates to high-quality polyurethane and polyurethane urea elastomers which exhibit unique combinations of processing characteristics, oxidation resistance, mechanical and mechanical/dynamic properties in particularly demanding applications. These polyurethane elastomers and polyurethane urea elastomers are based on novel polycarbonate polyols. | 01-15-2009 |
| 20090149621 | Polyurethanes cured with amines and their preparation - Polyurethane prepolymers are described which are prepared from 2,4′-diiso-cyanate diphenylmethane (2,4′-MDI), a polyol component and an aliphatic diisocyanate. These prepolymers can be cured with aliphatic, cycloaliphatic and/or aromatic amines to form a cured urethane elastomer. In comparison to cured urethane elastomers based on monomeric 2,4′-MDI, these prepolymers provide elastomers with extended pour life, i.e. they exhibit a slower rate of viscosity buildup after curative and prepolymer are mixed which results in a reduced propensity to crack during the curing process and gives the opportunity to cast larger parts. In comparison to polyurea/urethanes prepared from cured TDI-prepolymers and which optionally include H12-MDI, the prepolymers of the invention have better health and safety aspects. | 06-11-2009 |
