摘要:
Polyurethane coating compositions that provide transparent, abrasion-resistant, and water-washable anti-fog coatings when applied to a substrate and cured are described herein. These polyurethane coating compositions have surfactants that are chemically associated with the polyurethane so as to not leach out or wash away when the coating surface is soaked or washed with water. The polyurethane coating compositions comprise isocyanate-reactive surfactants, isocyanate-reactive salts of surfactants, carboxylic-reactive surfactants, or combinations thereof that are chemically bonded to the polyurethane. Articles coated with such polyurethane coating compositions, and processes for applying the coating compositions to a substrate, are also provided herein.
摘要:
A robust, two component adhesive for laminating flexible packaging material comprising a mixture of Component A and Component B. Component A comprises an isocyanate-functionalized compound. Component B comprises a mixture of a high functionality polyol containing at least four hydroxyl groups per molecule with at least two primary OH groups on the molecule and two secondary OH groups on the molecule and a trifunctional polyol containing three OH groups on the molecule. Component B can contain a difunctional polyol containing two OH groups on the molecule. The adhesive is robust and retains desirable properties when used at varying A:B mix ratios better than conventional laminating adhesives used at the same mix ratios.

摘要:
A composite of a resin member bonded to a vulcanized rubber member is obtained with using a rubber member vulcanized with a radical-generating agent (e.g., an organic peroxide) and a thermoplastic resin having at least 2 atoms, on average, selected from H and S atom per molecule, each atom having not less than 0.006 of an orbital interaction energy coefficient S represented by the following formula (1): S = C HOMO , n 2 / E c − E HOMO , n + C LUMO , n 2 / E c − E LUMO , n wherein E c :an orbital energy (eV) of a radical, C HOMO,n :a molecular-orbital coefficient of a highest occupied molecular orbital (HOMO) of an n-th H or S atom constituting a basic unit of the resin, E HOMO,n :an orbital energy (eV) of the HOMO, C LUMO,n :a molecular-orbital coefficient of a lowest unoccupied molecular orbital (LUMO) of the n-th H or S atom constituting the basic unit of the resin, E LUMO,n : an orbital energy (eV) of the LUMO, and above all represent a value calculated by a semiempirical molecular orbital method MOPACPM3. The thermoplastic resin includes a polyamide, a polyester, a PPE, a POM, a PPS, a polyolefinic resins, and the unvulcanized rubber may comprise a vulcanization-activating having plural polymerizable unsaturated bonds. The invention gives the composite of the resin bonded directly to the rubber firmly without adhesives in wide combinations of the resin and the rubber.
