Abstract
A laminate is presented and described, which has at least one layer that comprises an aminoplastic resin, where the aminoplastic resin is a condensate obtainable via reaction of a reaction mixture which comprises (1) formaldehyde, (2) a component comprising amino, imino, or amide groups, and (3) at least one alkoxysilane, organoalkoxysilane, or metal alkoxide. Laminates of this type feature particularly high resistance to microscratching.
Claims22
A laminate which has at least one layer that comprises an aminoplastic resin, wherein the aminoplastic resin is a condensate obtained via reaction of a reaction mixture at a pH of at least 8.0 wherein the reaction mixture comprises, based on its total weight,
- (1) from 10 to 20% by weight of formaldehyde,
- (2) from 25 to 45% by weight of a component comprising amino, imino, or amide groups, and
- (3) from 2 to 25% by weight of at least one alkoxysilane, organoalkoxysilane, or metal alkoxide.
The use of an aminoplastic resin which is a condensate obtained via reaction of a reaction mixture at a pH of at least 8.0, wherein the reaction mixture comprises formaldehyde, a component comprising amino, imino, or amide groups, and at least one alkoxysilane, organoalkoxysilane, or metal alkoxide as impregnation resin or liquid overlay in the production of impregnated material or of laminate, or for the surface-treatment of wood-derived materials.
A process for the production of an aminoplastic resin for use as impregnation resin or liquid overlay, or for the surface-treatment of wood-derived materials, comprising at least the following step:
- reaction of a reaction mixture which comprises formaldehyde, a component comprising amino, imino, or amide groups, and at least one alkoxysilane, organoalkoxysilane, or metal alkoxide at a pH of at least 8.0, preferably at least 9.0, and with particular preference at a pH of from 9.0 to 11.0.
