  • Patent number: 8816021
    Abstract: Low viscosity, radiation curable compositions have been developed that produce plastics with silicone rubber-like properties. These compositions have also been shown to give great adhesion to plastics. The combination of an ethylenically unsaturated oligomer with di- or polythiol compound, reactive diluents and a radical initiator will produce these properties. These materials can find use in many areas such as: Electronics packaging, displays, conformal coatings, seals, gaskets, fiber optics coatings, and golf ball coatings.

  • Patent number: 8759455
    Abstract: Single-component compositions are disclosed, which can be cured in two stages, wherein in the first curing stage, compositions pre-cured by means of moisture and having in particular plastic properties are formed, and wherein in the second curing stage, compositions cured by means of heat and having in particular elastic properties are formed. The two-stage compositions are suitable in particular as adhesives and have the great advantage that thanks to said two-stage compositions, an adhesive can be applied to a substrate, said adhesive cures by means of moisture in such a way that it can be handled and stored without problems, and said adhesive can be cured easily in an adhering step by means of heat only when needed.

  • Patent number: 8722230
    Abstract: A polyurethane binder prepared by a polyurethane compound having double bonds and by crosslinking the polyurethane compounds. The polyurethane binder having double bonds can be dispersed in water with the dispersant including a reactive group such as a carboxyl group, and thus an organic solvent is not required to produce an electrode. The crosslinked polyurethane binder with a high crosslinking density provides an excellent elastic force and binding force, and thus the electrode and the lithium battery employing the polyurethane binder have improved recovery properties and charge/discharge properties.

  • Patent number: 8668986
    Abstract: The present invention relates to aromatic aldimines, which are based on primary aromatic polyamines, which are solid at room temperature and liquid at room temperature and which have the lowest possible viscosity, hydrolyze with little odor, and can be used as blocked amines in curable compositions, in particular in compositions having one-component and two-component isocyanate groups. Said compositions have a relatively long open time, but cure surprisingly rapidly, said curing occurring without strong odor formation and without bubbling. In addition, the compositions have outstanding mechanical properties after curing, in particular high strength with high ductility, and good resistance to heat and moisture.

  • Patent number: 8653185
    Abstract: A method of forming ionically-charged, colorant nanoparticles involves forming in-situ ionically-charged polyurethane monomers, and forming an emulsion including the ionically-charged polyurethane monomers and a colorant nanoparticle. The method further involves polymerizing or crosslinking the ionically-charged polyurethane monomers in the emulsion, where the polymerizing or crosslinking chemically attaches the ionically-charged polyurethane monomers to a surface of the colorant nanoparticle to form an ionically-charged encapsulation layer on the surface.
