Abstract:

Urethane type sealants compounded from CF3 and C7F15-containing polyether triols, toluene diisocyanate and moisture cured were developed with good resistance to paint-stripper solvents, high mechanical properties and excellent adhesion to aluminum substrate. A number of fluorine-containing mono- and diglycidyl ethers, perfluorinated epoxides and fluorine-rich diamines and polyols were synthesized for compounding into urethane- and epoxy-type sealants. It is recommended to carry out a detailed evaluation of the compounds to select a candidate for field trial. Author
