Assignee:

Polytek Development Corp. - Lebanon NJ

International Classification:

C08G 1810

US Classification:

528 60

Abstract:

Provided by this invention are thixotropic polymer compositions, which are useful upon curing to make tough coatings, sealants, adhesive bonds and molds. The compositions can be supplied to the site of use as two low viscosity liquid parts, which when mixed provide rapid onset of thixotropy. One or more polyisocyanates and one or more aromatic diamines are used in making the compositions. Processes for making coatings, sealants, adhesive bonds and molds by use of the compositions are also provided.
