Abstract
Novel coating compositions containing a polymer, a hydrazide and a silane, methods of making and using such compositions and a substrate coated with such coating compositions.
Claims62
A coating composition comprising:
- a polymer having at least one reactive group;
- a hydrazide;
- and
- an organosilane treated pigment which is obtained in-situ during formation of the coating composition;
- the coating composition containing substantially no isocyanate or formaldehyde.
A method of coating comprising
- providing a composition containing a polymer, a hydrazide and an organosilane treated pigment which is obtained in-situ during formation of the coating composition, the polymer having at least one reactive group;
- and
- applying the composition to a substrate;
- the coating composition containing substantially no isocyanate or formaldehyde.
A method of preparing a coating composition comprising
- combining a polymer having at least one reactive group, a hydrazide group, and
- an organosilane treated pigment, the organosilane treated pigment being obtained in-situ during formation of the coating composition, the coating composition containing substantially no isocyanate or formaldehyde.
A coating comprising a polymer crosslinked by an organo group of an organosilane treated pigment, and a hydrazide, the polymer having at least one reactive group, the coating containing substantially no isocyanate or formaldehyde.
A coated substrate comprising a substrate coated with a coating comprising a polymer crosslinked by an organo group of an organosilane treated pigment, and a hydrazide, the polymer having at least one reactive group, the coating containing substantially no isocyanate or formaldehyde.
A coating comprising a polymer crosslinked by an organo group of an organosilane treated pigment, and a hydrazide, the polymer having at least one reactive group and the hydrazide not being attached to the polymer, the coating containing substantially no isocyanate or formaldehyde.
A waterborne coating composition made by combining a polymer having at least one reactive group, a hydrazide having the formula:
- silane and pigment;
- the silane and pigment reacting in-situ during formation of the coating composition to yield an organosilane treated pigment, the coating composition containing substantially no isocyanate or formaldehyde.
