Abstract
The present invention relates to a dispersion for manufacturing of resin-impregnated papers, as can be used for the manufacturing of abrasion-resistant (micro scratch-resistant) surfaces, such as laminate floors, furniture surfaces or laminates (CPL, HPL). The invention relates also to a corresponding method for manufacturing of such surfaces as well as to corresponding manufactured products. Thereby, the dispersion contains for example (in weight percent) 30 to 75% water and 10 to 65% corundum particles with a particle size of F400 to F2000 as well as further additives in small quantity. This dispersion can be introduced into a liquid amino resin mixture to impregnate paper.
