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. |

Polyisocyanurate foams are disclosed which are characterized by a combination of a high degree of fire resistance with low smoke evolution, low foam friability yet high compressive strength, and, most unexpectedly, the formation of a protective intumescent char over unburnt foam when the foam is subjected to combustion.This combination of advantageous features is achieved by employing in the foam forming reaction a minor amount of a polyol mixture prepared by the transesterification, with a glycol of molecular weight from about 60 to about 400, of a residue obtained from the manufacture of dimethyl terephthalate. |

A process for producing a structural laminate having a polyisocyanurate foam core wherein a mixture of an organic polyisocyanate and diethylene glycol are applied to a facing sheet. The facing sheet comprises paper coated on both sides with a moisture vapor impermeable material. The coated facing sheet is then placed in an oven at 150* to 200* F, whereupon the mixture cures to a polyisocyanurate foam of uniform strength.

The present invention relates to composite roof structures and their preparation. The composite roof structure is prepared by applying a one-part, moisture curable, foaming, polyurethane adhesive composition to the roof deck, placing the roofing material in contact with the adhesive composition, and allowing the adhesive mixture to foam, fill, and cure. If multiple layer of the roofing material are used to form the composite roof structure, then the above procedure may be used to adhere each of the roofing material layers. |

The invention is a two part urethane adhesive in which the B side component is derived chiefly from a vegetable oil, preferably soy oil. Preferably the vegetable oil derivative is a hydroxylated vegetable oil which is present in the B side component at a concentration from 65 to 98 weight percent Optionally, a phosphated soy oil can be present in an amount from 0.1 to 15 weight percent to enhance the adhesive properties, particularly for use on metals. Also, water can be present in an amount from 0.1 to 10 weight percent with a slight amount of a surfactant to stabilize the mixture. Catalysts are included in the B side component to reduce the amount of the A side component and to accelerate curing of the adhesive. The A and B side components are admixed in amounts which provide from 40 to 90 weight percent of bio-based content in the adhesive. The adhesive also has a volatile organic content (VOC) less than 2 weight percent and most preferably no VOC. |
