Surface finishing agent BYK-349 and defoamer BYK-093 for mold paper applications.
Resolving the low wettability of the release paper and the incorporation of bubbles [Surface modifier BYK-349, Defoamer BYK-093].
★Release paper surface modifiers and defoamers In recent years, the transition from solvent-based to water-based systems has gained significant importance. In water-based systems, the following issues frequently arise: • Low wettability of release paper • Entrapment of bubbles BYK-349 and BYK-093 are examples of additives that can solve these problems. 【BYK-349】 A silicone-based surfactant with a significant ability to reduce surface tension, improving the wettability of the substrate. It does not contribute to improved slip properties on the surface. Suitable for systems that do not contain co-solvents. General-purpose product. 【BYK-093】 Water-based defoamer • Applicable to a wide range of uses • Excellent long-term stability (during high and low-temperature storage) • Fewer surface defects (cloudiness, crater-like defects, etc.) due to high compatibility • Easy to mix, recommended for post-addition • Can be used in combination with other defoamers • APEO-free, formaldehyde-free (VdL RL-03), low VOC

Applications/Examples of results
Application Example: BYK-093 in Difficult Coating Processes Application of Reverse Roll The application of PU/acrylic finishes using reverse roll (Gemata) is becoming increasingly popular. This new coating method using silicone rubber cylinders introduces a large amount of air, making an appropriate defoamer necessary. When applying high-gloss finishes, this issue becomes very serious, as the entrapped fine air bubbles dramatically affect gloss and transparency. BYK-093 often demonstrates excellent efficiency and good compatibility.
