Method of marking paved surfaces using a curable two-part epoxy composition comprising curable liquid epoxide and amine co-curative

摘要

The disclosed coating method has the ability to satisfy some or all of the very troublesome requirements of highway marking or striping and is therefore useful to mark or stripe paved surfaces. The method involves:PP(a) supplying to the point of application an amine co-curative which includes an aliphatic amine (e.g. trimethyl hexamethylene diamine) and a cycloaliphatic amine (e.g. cyclohexane-bis methylamine!);PP(b) supplying to the point of application a suitable curable liquid vicinal epoxide composition;PP (c) applying the co-curative and the liquid epoxide to the paved surface (preferably after intimately mixing the co-curative and the liquid epoxide); andP P(d) permitting the resulting mixture to cure in situ on the paved surface.
