  • Patent number: 8026333
    Abstract: This invention relates to a protected organotin-based catalyst system for polyurethane synthesis that is useful in coatings applications. The catalyst has a formula according to; R1aR2bR3cSn[CH(OX)R4]d, wherein R1, R2, and R3 are the same or different and represent an optionally substituted hydrocarbyl, aromatic, alkoxide, amide, halide or stannyl group, R4 represents an optionally substituted hydrocarbyl or optionally substituted aryl group. a, b, and c are independently 0, 1, 2, or 3; d is 1, 2 or 3; and a+b+c+d=4; and X is an acid-labile or moisture-labile protecting group. When a coating mixture comprising the catalyst is sprayed and/or applied to a substrate as a thin film in air, the catalyst is activated. For solvent-based refinish systems comprising hydroxyl and isocyanate species at high solids levels, the catalyst system therefore provides extended viscosity stability, i.e., pot life.

  • Patent number: 7977446
    Abstract: This invention relates to an organotin-based catalyst system for polyurethane synthesis that is useful in coatings applications. The catalyst has low activity in the absence of oxygen. When a coating mixture comprising the catalyst is sprayed and/or applied to a substrate as a thin film in air, the catalyst is activated. For solvent-based refinish systems comprising hydroxyl and isocyanate species at high solids levels, the catalyst system therefore provides extended viscosity stability, i.e., pot life.

  • Publication number: 20100213454
    Abstract: There is provided a process for forming a contained second layer over a first layer. The process comprises forming the first layer having a first surface energy and then treating the first layer with a photocurable surface-active composition which is a fluorinated ester or fluorinated imide of an ?,?-unsaturated polyacid; exposing the photocurable surface-active composition patternwise with radiation resulting in exposed areas and unexposed areas; developing the photocurable surface-active composition to remove the unexposed areas resulting in a first layer having untreated portions in the unexposed areas and treated portions in the exposed areas, where the treated portions have a second surface energy that is lower than the first surface energy; and forming the second layer on the untreated portions of the first layer. There is also provided an organic electronic device made by the process.

  • Patent number: 7217495
    Abstract: Fluorinated polymers, photoresists and associated processes for microlithography are described. These polymers and photoresists are comprised of a fluoroalcohol functional group which simultaneously imparts high ultraviolet (UV) transparency and developability in basic media to these materials. The materials of this invention have high UV transparency, particularly at short wavelengths, e.g., 157 nm, which makes them highly useful for lithography at these short wavelengths.
