Abstract
Damage resistant high pressure decorative laminate having excellent scratch, mar, scrape and abrasion resistance, as well as excellent appearance and cleanability and methods of producing same.
Claims8
A binderless damage resistant decorative laminate having improved scratch, mar, scrape and abrasion resistance comprising at least one backing layer sheet and a thermoset resin impregnated paper sheet laminated thereto, said decorative paper sheet having thereon an abrasion resistant coating composed of a mixture consisting essentially of:
- (a) abrasion resistant mineral particles having a particle size of from about 15 microns to about 45 microns in a concentration of from about 8 to about 12 grams per square meter of surface area;
- (b) a silane coupling agent in an amount dependant upon the concentration of the abrasion resistant mineral particles;
- (c) a thickening agent in an amount sufficient to suspend said abrasion resistant particles;
- and
- (d) a small but effective amount of polyethylene glycol stearate to enhance surface slip and improve scrape resistance of the laminate.
