				BYK-LP N 6640 is a dispersing additive for aqueous emulsion paints.  It increases gloss, reduces viscosity and provides good storage stability for the system.  BYK-LP N 6640 improves wetting of pigments and reduces the "flash-rust" tendency in latex paints.  This additive does not contain alkylphenolethoxylates.  |
