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 (Ia) R1aSiX(4-a), R3cSiX(4-c)(II), and inorganic particles. X is methoxy, ethoxy, n-propoxy or i-propoxy. R1 is an organic radical selected from the group including methyl, ethyl, propyl, or vinyl, and has at least one functional group Q1, selected from the group including acrylic, acryloxy, methacrylic, methacyloxy, or epoxy. R3 is a non-hydrolyzable organic radical selected from the group including C1-C10 alky, C6-10 aryl, wherein C is 1, 2, or 3, and the inorganic particles have a size between 2 nm and 400 nm.
Claims20
