BYK-DYNWET is one of BYK's brand for surface additives. During the application of liquid coatings on surfaces a multitude of surface defects can occur. The cause for this is, among others, significantly differing surface tensions. If, for example, the surface tension of the coating is higher than that of the substrate, this manifests itself in poor wetting (high contact angle) and, with that poor adhesion and cratering. Also after the application and while the coating is drying, local surface tension differences can cause unfavorable leveling and the floating of pigments. BYK-DYNWET additives are silicone-free and are especially used to reduce dynamic surface tension in e.g. aqueous coatings and printing inks.
