Abstract

An impregnate with antistatic properties for use in laminates or for coating wood-based panels is disclosed. A resin used for impregnating and/or coating paper may include carbon-based particles, at least one compound of the general formula (I) R1aR2bSiX(4-a-b), and/or hydrolysis products thereof. X is H, OH, or a hydrolysable moiety selected from the group including halogen, alkoxy, carboxy, amino, monoalkylamino or dialkylamino, aryloxy, acyloxy, or alkylcarbonyl. R1 is an organic moiety selected from the group including alkyl, aryl, or cycloalkyl, which may be interrupted by —O— or —NH—. R1 has at least one functional group Q1 selected from a group including a hydroxy-, amino, monoalkylamino, carboxy, mercapto, alkoxy, aldehyde, acrylic, acryloxy, methacrylic, methacryloxy, cyano, isocyano or epoxide group. R2 is a non-hydrolyzable organic moiety selected from the group including alkyl, aryl, alkenyl, alkynyl, cycloalkyl, cycloalkenyl; a is 0, 1, 2, or 3, and b is 1, 2, 3, or 4.
