Polyesters Crosslinked with
Melamine Formaldehyde
U.S. 8,562,775 B2
OMNOVA Solutions Inc. has been granted a method of providing an article with
a thermoformed exterior, outward facing surface, the method comprised of
thermoforming to an exterior surface of
the article a composite so as to provide a
laminate, the composite is comprised of a
substrate bearing a coating on a surface
opposite the side of the substrate contacting the exterior surface of the article; and
heating the laminate to a temperature of
at least 83° C for at least 30 seconds so
as to cure the laminate, thereby providing
the thermoformed surface, the coating
being the partially crosslinked product of
ingredients that comprise a polyester, an
alkyl-etherified melamine formaldehyde
compound and, based on the combined
weight of the polyester and alkyl-etherified melamine formaldehyde compound
from approximately one- 15 percen of a
thermally activatable catalyst.
