AQUEOUS DISPERSION OF A POLYURETHANE COMPRISING A DICARBOXYLATE WITH ONE OR TWO SECONDARY AMINO GROUP
An aqueous dispersion of a polyurethane wherein the polyurethane is obtained by reacting di- or polyfunctional cyanates, diols, a dicarboxylate with one or two secondary amino groups and optionally further compounds.
Methods for reactive three-dimensional printing by extrusion
Methods of printing a three-dimensional object using co-reactive components are disclosed. Thermosetting compositions for three-dimensional printing are also enclosed.
Liquid coatings including expandable graphite
A method of preparing a seamless membrane over a flat or low-sloped roof, the method comprising applying multiple layers of a liquid coating composition over a roof surface, where said step of applying includes applying at least one layer of a liquid coating composition that includes expandable graphite.

Methods for cross-linking thermoplastic polyurethane covers for golf balls
Golf balls having covers made of thermoplastic polyurethane compositions are provided. Multi-piece golf balls can be made. In one embodiment, the outer cover layer is formed from a composition comprising a thermoplastic polyurethane and multi-functional hydroxyl compound. Mixtures of multi-functional amines and imines, and multi-functional isocyanates, and solvent, can be applied to the outer cover to form at least a partially cross-linked cover. The cover composition can further include catalysts, ultraviolet (UV)-light stabilizers, and other additives. The coating methods have many benefits and the finished balls have good physical properties.
SINGLE-COMPONENT POLYSILOXANE NON-SKID / NON-SLIP COATINGS
Disclosed is a composition having: an organosilane polymer, a polyamide polymer; and an abrasive aggregate. The organosilane is made by: reacting an amino-functional alkoxysilane with one or more polyisocyanates to form one or more adducts having an unreacted isocyanate group; and reacting the adducts with one or more polyfunctional amino- and/or hydroxyl compounds so that the polymer contains no unreacted isocyanate groups. The polyfunctional amino- and/or hydroxyl compound has a cycloaliphatic group or an aromatic group. The composition can be used to make a single-component polysiloxane non-skid/non-slip coating that is applied by rolling, spraying, or troweling and cures with atmospheric moisture.
PROTECTIVE MATERIAL AND WIRELESS COMMUNICATION DEVICE
Provided is a protective material that protects a wireless communication portion for wireless communication, comprising a substrate formed of a foam synthetic resin and a coating layer of a polyurea resin covering at least a front side surface of the substrate. The wireless communication device includes a wireless communication portion for wireless communication and a protective material.
POLISHING PAD EMPLOYING POLYAMINE AND CYCLOHEXANEDIMETHANOL CURATIVES
A chemical-mechanical polishing pad comprising a thermosetting polyurethane polishing layer includes an isocyanate-terminated urethane prepolymer, a polyamine curative, and a cyclohexanedimethanol curative. The polyamine curative and the cyclohexanedimethanol curative are in a molar ratio of polyamine curative to cyclohexanedimethanol curative in a range from about 20:1 to about 1:1.
Bio-derived polyurethane fiber
Included are elastomeric fibers and method for preparing such fibers, which include a bio-derived butanediol. The bio-derived butanediol is used to prepare a polymeric glycol composition, which is contacted with a diisocyanate and spun to provide an elastomeric fiber.
