Abstract: The invention relates to a thermoplastic article having a continuous polymeric phase and a discontinuous discrete phase distributed within the continuous phase. The discontinuous phase may be inorganic materials or an organic phase. The volume fraction of the discrete phase at the surface of the article is plus or minus 15% of the concentration of the additive as compared to the concentration of the additive in the bulk of the material (>20 micrometers). The invention also relates an article where the discrete additive forms domains in the surface region—potentially beneficial for gloss reduction or electrical conductivity. The invention finally relates to a process for forming a thermoplastic article with surface additive enhancement, with inclusion of inductive heating of one or more surfaces of the mold to induce the unique distribution.

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.
