This product prevents ghosting (wipe-marks) if recoated with the same paint. It typically does not cause rewetting problems and does not influence recoatability. These additives provide a slight reduction of surface tension of paint systems. Therefore, they improve flow and leveling as well as display partial defoaming properties. Additionally, they prevent Bénard cell formation. view less | Request Sample |

This product is a silicone leveling additive with defoaming properties. It is particularly suitable for non-polar to medium-polar paint systems. Its defoaming activity rises with increasing coating polarity. In automotive and industrial coatings, BYK-320 will not exhibit problems with ghosting or telegraphing. To avoid these effects BYK-320 should be added to the paint which has to be recoated. view less | Request Sample |
