  • Patent number: 10450402
    Abstract: An isocyanate reactive composition for making a polyurethane foam includes a tertiary amine urethane catalyst comprising a di(C1-C4)alkyl fatty alkyl amine and a polyester polyol. The use of one or more of fatty alkyl tertiary amine serves to reduce hydrolysis of the polyester polyol in the isocyanate reactive composition.
    Type: Grant
    Filed: June 13, 2018
    Date of Patent: October 22, 2019
    Assignee: Evonik Degussa GmbH

  • Patent number: 9290604
    Abstract: Alkylethoxylate alcohols or mixtures of alkyl alcohol ethoxylate with an average HLB value between 10 and 15 as compatibilizers for water blown polyurethane foam formulations that are substantially free of nonylphenol ethoxylates are disclosed. The HLB is defined as the mass percent of average structure of the compatibilizer that is hydrophilic, divided by 5. The compatibilizer is mixed into the B-side of the polyurethane formulation. The B-side of the spray foam formulations comprise polyol, water, amine catalyst, and the compatibilizer of the invention such that the water is present at about 2% to about 30% by weight of the B-side formulation, and the compatibilizer is present at about 1% to about 30% by weight of the B-side formulation. The B-side of the formulation may further comprise metal catalysts, flame retardants, silicone surfactants, cell openers, antioxidants, as well as other additives.

  • Publication number: 20080269365
    Abstract: A composition for making a polyurethane foam includes a fugitive tertiary amine urethane catalyst and amidoamine and/or imidazoline property enhancing additives. The inclusion of one or more of these property enhancing additives serves to reduce or eliminate physical property and surface deterioration of polyurethane foams made at reduced density.
