  • Radically polymerizable compositions
    Patent number: 11518834
    Abstract: Polymerizable compositions comprising a radically polymerizable resin can be polymerized in the absence of a peroxide initiator and other undesirable components. The polymerizable compositions and methods employ a manganese- or iron-containing salt or organic complex and a 1,3-dioxo compound with one or more other components. The polymerizable compositions have better storage stability and reduced gel time-drift.

  • Acetoacetyl thermosetting resin for gel coat
    Patent number: 11091651
    Abstract: Zero VOC thermosetting gel coat and laminating resin compositions, and composites and articles, are produced using a multifunctional Michael acceptor, a multifunctional Michael donor and a base catalyst. The obtained low viscosity resin is useful for producing zero VOC gel coats and laminates having excellent curability at ambient temperatures.

  • Fillers
    Patent number: 10160882
    Abstract: A powdered filler composed of solid particles of a cured thermosetting composition comprising a resin modifier such as fumed silica, methods of preparing the cured solid particles, compositions comprising the powdered filler, and articles made from the compositions are disclosed. In embodiments, the solid particles are spherical shaped, transparent or translucent, and have a mean particle size of less than 20 ?m.

  • Phenolic modified polyesters and aqueous dispersions
    Patent number: 9988552
    Abstract: Substrates, such as the interior surfaces of food containers, can be coated using a composition including a phenolic modified polyester resin prepared using a formulation not including Bisphenol A as a component or subcomponent. These polymers arid subsequent coatings are free of both mobile and bound Bisphenol A moieties. These polymers and resulting coatings have properties similar to and, in some embodiments, superior over comparable conventional polyester coatings.
