  • Publication number: 20210253859
    Abstract: The present disclosure provides dual curable compositions having both radiation curing and shadow curing mechanisms. The compositions comprise silicon-organic hybrid polymers having rapid shadow curing by a 2 part isocyanate-polyol reaction and/or a 2 part cyclic carbonate-amine reaction. The compositions can be used as adhesives or coatings. The use of the compositions according to the disclosure is particularly preferred for use in electro-optical components especially for automobile display adhesives applications.

  • Patent number: 10005919
    Abstract: Curable sealant compositions having low temperature sealing ability improved over convention curable sealing compositions. The composition is flowable and can be cured to a cross linked form to provide cured reaction products that exhibit elastomeric properties. The curable elastomeric sealant composition can include a cross linkable elastomeric oligomer; an initiator or cross-linking agent; a glassy monomer and/or a rubbery monomer; and optionally one or more additives. Cured reaction products of the composition have a single Tg and retain a higher sealing force at low temperatures (but above the cured product Tg) as compared to a curable composition made from the same cross linkable elastomeric oligomer but without the glassy and/or rubbery monomer.

  • Patent number: 8197990
    Abstract: A fuel cell, having improved sealing against leakage, includes a sealant disposed over the peripheral portions a membrane electrode assembly such that the cured sealant penetrates a gas diffusion layer of the membrane electrode assembly. The sealant is applied through liquid injection molding techniques to form cured sealant composition at the peripheral potions of the membrane electrode assembly. The sealant may be thermally cured at low temperatures, for example 130° C. or less, or may be cured at room temperature through the application of actinic radiation.
