  • Patent number: 11142488
    Abstract: A process for producing a coated particle to provide controlled release characteristics. In this process the mixing of the substrate and coating is made in a mixing device and that mixture is then transferred to a reactor vessel different from the mixing device where the chemical curing of the coating over the particles takes place. Several layers of coating can be applied by repeating the steps and it can be run in a fully continuous manner.

  • Publication number: 20210032520
    Abstract: Methods of melting ice using ice-melt compositions including calcium chloride coated with a lignosulfonate material are disclosed. The ice-melt compositions can be useful as ice-melt products with improved safety. A method can include applying an ice-melt composition to ice, the ice-melt composition comprising coated particles. Each coated particle can include a core comprising calcium chloride and a coating at least partially surrounding the core, the coating comprising a lignosulfonate material.

  • Patent number: 6706414
    Abstract: The uncrosslinked liquid oligomeric compositions of this invention are made by the Michael addition reaction of acetoacetate-functional donor compounds with multifunctional acrylate acceptor compounds where the equivalent ratios of multifunctional acrylate to acetoacetate vary from ≧1:1 to ≧13.2:1 depending on the functionality of both multifunctional acrylate and acetoacetate in the presence of a catalyst comprising an epoxy moiety and a quaternary salt. Unusable gelled or cured oligomer products occur below the claimed ranges. The liquid oligomers of this invention are further crosslinked to make coatings, laminates and adhesives.
