20090124766 | POLYSILOXANE-MODIFIED POLYISOCYANATES, PROCESSES FOR PREPARING THE SAME, AND POLYURETHANES CONTAINING THE SAME - Processes for preparing siloxane-modified polyisocyanates, the processes comprising: providing a polyisocyanate reactant; and reacting the polyisocyanate reactant with a hydroxyl-containing siloxane having a number-average molecular weight of 200 to 3000 g/mol and an average OH functionality of greater than or equal to 1.8, and corresponding to the general formula (I): | 05-14-2009 |
20090209711 | AQUEOUS MODIFIED POLYISOCYANATE, NON-YELLOWING COATING COMPOSITION, AND ADHESIVE COMPOSITION - An aqueous modified polyisocyanate intended to be dispersed in an aqueous medium for use and obtained by reacting an HDI derivative with (A) a modifying agent composed of a methoxy polyoxyalkylene glycol mainly comprising an ethylene oxide unit, (B) a modifying agent composed of a hydroxyl group-terminated polyoxyalkylene glycol produced by using an alcohol having 8 or more carbon atoms as an initiator and mainly comprising a propylene oxide unit, and (C) a modifying agent composed of an ester compound having at least one hydroxyl group with an alkali metal salt of sulfonic acid introduced therein, wherein the concentration (calculated value) of the alkali metal salt of sulfonic acid derived from the modifying agent (C) is 1.5 to 25 μmol/g. | 08-20-2009 |
20100137528 | Method for Functionalizing Nanotubes and Improved Polymer-Nanotube Composites Formed Using Same - A polymerizable ligand comprising, in one embodiment, a polyaromatic compound, with a terminal functional group, non-covalently bonded to the sidewalls of carbon nanotubes. This structure preserves the structural, mechanical, electrical, and electromechanical properties of the CNTs and ensures that an unhindered functional group is available to bond with an extended polymer matrix thereby resulting in an improved polymer-nanotube composite. | 06-03-2010 |
20130102738 | SILANE-CROSSLINKING COMPOSITIONS - The invention provides curable adhesives of high tensile sheer strength, which contain an a-silane-terminated polyurethane prepolymer containing low molecular weight polyether or polyester groups in the polymer backbone, and a silane-terminated polyether polymer containing polyether groups of higher molecular weight. | 04-25-2013 |
20150308044 | Press jacket for press roller - A press jacket for a press roller, in particular for a press roller of a shoe press for dewatering a fibrous material web, in particular a paper, cardboard, tissue or pulp web, or a transport band, in particular for a machine for producing or treating a fibrous material web, in particular a paper, cardboard or tissue machine, includes at least one layer containing polyurethane which contains a polyurethane matrix with a mixture of at least two prepolymers. Each prepolymer is a reaction product of two different polyols with a polyisocyanate. | 10-29-2015 |
