Foaming, moisture-curing prepolymers containing at least one group of formula I:&#x2014;X-A-Si(Z)(OR)&#x2003;&#x2003;(I),and at least one of formula II:&#x2014;N(R)&#x2014;C(O)&#x2014;Y&#x2014;R&#x2003;&#x2003;(II),and adhesive or assembly foams produced therefrom.

Prepolymers containing silyl groups, the production thereof and the use of the same in polyurethane foams

A one-pack polyurethane adhesive containing a polyisocyanate prepolymer and at least one aminoether polyol, having a molar ratio of ether groups to amino nitrogen in the aminopolyether polyol of 7 to 30.

Fast setting 1k-polyurethane glue

A process for the production of compounds which contain at least one urea group and at least one silyl group. The process involves reacting a compound containing at least one amino group and a carbamate compound. The compounds produced by this process are useful as surface coating compositions, foams and adhesives.

Polymers with urea groups and silyl groups and production and use thereof

Described is an NCO-group-containing polyurethane prepolymer madefrom polyisocanyates and polyols derived from natural oils. The invention is characterized in that the polyol is obtained by transesterification in the presence of basic lithium compounds. Together with a tertiary amine used to accelerate the moisture curing, the storage stability is thus increased considerably. Up to 4.0 mmol of the lithium compound is used per kilogram of polyol, and 0.1 to 2.0% by wt. of the amine, relative to the total weight of the composition, is used as the accelerator. The polyurethane prepolymer is suitable not only for the production of adhesives but also for the production of foamed materials, in particular those dispensed from throw-away pressure vessels.

Process for the production of reaction mixtures containing ester polyols

Process for the production of modified triglycerides which contain epoxide groups, secondary hydroxyl groups and ether groups. The invention particularly relates to the production of reaction products of epoxidized triglycerides, for example epoxidized soy oil, with polyfunctional alcohols, for example glycols. The products so prepared are valuable starting materials, particularly for the production of alkyd resins.

Process for the preparation of modified triglycerides

The invention relates to isocyanate-terminated polyurethane prepolymers containing a stoichiometric excess of an isocyanate component comprised of one or more aromatic isocyanates containing on average from 2 to 4 isocyanate groups per molecule and a polyol component comprised of an oleochemical polyol prepared by epoxidation of a triglyceride containing olefinic unsaturation and subsequent ring opening with an alcohol. In use, accelerators, flameproofing agents, blowing agents and, optionally, liquefying agents, dyes and/or stabilizers, are included. The oleochemical polyol does not contain any free epoxide groups and is obtained by complete ring opening of epoxidized triglycerides of a fatty acid mixture containing at least partly olefinically unsaturated fatty acids with one or more C.sub.1 -C.sub.12 alcohols and partial conversion by alcoholysis or transesterification of the triglyceride derivatives to alkyl ester polyols containing from 1 to 12 carbon atoms in the alkyl radical. A process for the production of these polyurethane prepolymers and to their use as starting materials for the production of polyurethane foams is included.

Paint stripping foam

A method of providing a foam accoustical insulation, thermal insulation, and/or moisture-barrier, in which a polyurethane prepolymer composition is applied to a substrate in situ and then expanded and cured using water pre-applied to the substrate, ambient atmospheric moisture, and/or added atmospheric moisture.

Polyurethane insulating foam

The present invention relates to one component polyurethane foam compositions which comprise mixtures of prepolymers of a polyol and an excess of isocyanate; the usual adjuvants for polyurethane foams, an expanding gas under pressure and a polysiloxane compound with antifoam activity stored in a valved pressure vessel.
