  • Urethane bonding method and laminate
    Patent number: 4636425
    Abstract: A method of surface bonding elements with a two component polyurethane foam, particularly where one of the surfaces to be joined is relatively porous, including contoured fiberglass panels, carpet, foam and fibrous paneling and the resultant bonded structure. The method includes spraying the liquid foamable polyurethane in a fine mist under pressure on one of the surfaces to be bonded to form dispersed discrete liquid polyurethane droplets; permitting the polyurethane droplets to foam and expand in discrete foam pods; applying the second surface to be joined while said polyurethane foam pods are between 20% and 60% of full cure; and, completing the cure of the polyurethane foam, preferably under moderate heat and pressure.

  • Alkylene oxide adducts of vicinal toluenediamine and co-initiators, useful for rigid polyurethane foams
    Patent number: 4469822
    Abstract: The subject invention relates to polyol compositions which are alkylene oxide adducts of a mixture of initiators comprising vicinal toluenediamine and an initiator selected from the group consisting of glycerin, pentaerythritol, sucrose, sorbitol, trimethylolpropane, and mixtures thereof. Low molecular weight diols may also be used as a co-initiator in combination with the glycerin, pentaerythritol, sucrose, sorbitol, trimethylolpropane, and mixtures thereof.The subject polyol compositions are particularly useful in the preparation of rigid polyurethane foams.

  • Polysiocyanurate-polyurethane foams
    Patent number: 4410641
    Abstract: Polyisocyanurate-polyurethane foams are prepared by reacting an organic polyisocyanate with oxyethylated aromatic amines and diols having equivalent weights from 31 to 100 and at an isocyanate index of 150 to 500 in the presence of a trimerization catalyst and a blowing agent.

  • Alkylene oxide adducts of vicinal toluenediamine
    Patent number: 4397966
    Abstract: The subject invention relates to polyol compositions which are alkylene oxide adducts of a mixture of initiators comprising vicinal toluenediamine and an initiator selected from the group consisting of ammonia, an aliphatic amine having a molecular weight of from 20 to 120, an alkanolamine having a molecular weight of from 50 to 120, and mixtures thereof. Low molecular weight diols may also be used as a co-initiator in combination with ammonia, an aliphatic amine, an alkanolamine, or mixtures thereof.The subject polyol compositions are particularly useful in the preparation of rigid polyurethane foams.
