| 20100280209 | CURABLE COMPOUND COMPRISING SILYLATED POLYURETHANE - A method for producing a silylated polyurethane including the steps: (A) converting (i) at least polyol compound having a molecular weight of 4,000-30,000 g/mol and at least one monofunctional compound relative to isocyanates and (ii) at least one diisocyanate at a stoichiometric excess of the sum of the polyol compound(s) and monofunctional compound relative to the diisocyanate compound(s), whereby a hydroxyl-terminated polyurethane prepolymer is formed; and (B) converting the polyurethane prepolymer and one or more isocyanate silane(s) of the formula (I): OCN—R—Si—(R1) | 11-04-2010 |
| 20100331480 | HARDENABLE COMPOSITIONS CONTAINING SOFT-ELASTIC SILYLATED POLYURETHANES - Silyated polyurethanes can be manufactured by (A) converting (i) at least one polyol compound A with a molecular weight of 500-20,000 Dalton, in particular 4000-10,000 Dalton, (ii) with a dihalogenide to a polyol compound B with a molecular weight of 4000-40,000 Dalton, in particular 8000-20,000 Dalton, and subsequent (B) conversion of this polyol B with one or more isocyanatosilanes of formula (1): OCN—R—Si—(R1)m(-OR2)3-m where m is 0.1 or 2, each R2 is an alkyl radical with 1 to 4 carbon atoms, each R1 is an alkyl radical with 1 to 4 carbon atoms and R is a difunctional organic pump. These silylated polyurethanes are suited to use as adhesives, sealant or coating agent in preparations containing one or more such silylated polyurethane. | 12-30-2010 |
| 20110034627 | CURABLE COMPOSITIONS CONTAINING SILYLATED POLYURETHANES - Silylated polyurethanes can be manufactured by reacting at least one polyol compound, having a molecular weight from 4000 to 20,000 dalton, with a diisocyanate, with a stoichiometric excess of the diisocyanate compound with respect to the polyol compound or compounds, with the result that a polyurethane prepolymer that is isocyanate-terminated is formed; and by subsequently reacting the polyurethane prepolymer with one or more OH-terminated silanes of formula (1) to yield a polyurethane having predominantly terminal alkoxysilyl groups. In formula (1), m is equal to 0, 1, or 2, R | 02-10-2011 |
| 20110071254 | CURABLE COMPOSITIONS CONTAINING SILYLATED POLYETHER BLOCK POLYMER-BASED POLYURETHANES - The invention relates to a silylated polyurethane that is manufactured by reacting at least one polyether compound having an OH number per DIN 53783 between 3 and 20 mg KOH/g, made up of at least two polyoxyalkylene blocks A and B, the number of carbon atoms in the alkylene units of blocks A and B differing by at least 1, with one or more isocyanatosilanes of formula (I): OCN—R—Si—(R | 03-24-2011 |
