BYK-333 Silicone-containing surface additive for solvent-free, solvent-borne and aqueous coating systems, printing inks and adhesive systems as well as ambient-curing plastic systems. Strong reduction of surface tension. Product Data Composition Polyether-modified polydimethylsiloxane. Typical Properties The values indicated in this data sheet describe typical properties and do not constitute specification limits. Density (20 °C): 1.04 g/ml Food Contact Legal Status For the current food contact legal status, please contact our product safety department or visit byk for further information. Storage and Transportation Separation or turbidity may occur at temperatures below 5 °C. Warm to 20 °C and mix well. Applications Coating and Printing Ink Industry Special Features and Benefits The additive provides a strong reduction of the surface tension of the coatings and printing inks. It therefore particularly improves substrate wetting and avoids cratering. Surface slip and gloss are also increased. In aqueous systems it improves the anti-blocking properties. Recommended Use The additive is particularly recommended for all solvent-borne, solvent-free and aqueous coatings, printing inks and overprint varnishes. Recommended Levels 0.05-0.3 % additive (as supplied) based upon total formulation. In aqueous and UV systems up to 1 %. The above recommended levels can be used for orientation. Optimal levels are determined through a series of laboratory tests. Dilution before processing can make it easier to dose. Data Sheet Issue 11/2012 2 BYK-333 Incorporation and Processing Instructions The additive can be incorporated during any stage of the production process, including post-addition. Special Note Unlike so-called silicone oils, this additive is very user-friendly. Nevertheless, it should be determined in a series of tests whether foam is stabilized in certain systems. Similarly, the recoatability and cratering should be checked. Adhesives & Sealants Special Features and Benefits BYK-333 is a highly effective silicone additive. It provides a strong reduction of surface tension, thereby improving the wetting of critical substrates. Recommended Use It is particularly recommended for improving the substrate wetting of adhesive systems based on polyurethanes, epoxies and acrylates. Recommended Levels 0.05-0.3 % additive (as supplied) based upon total formulation. The above recommended levels can be used for orientation. Optimal levels are determined through a series of laboratory tests. Incorporation and Processing Instructions The additive can be incorporated during any stage of the production process, including post-addition. Special Note Unlike so-called silicone oils, this additive is very user-friendly. Nevertheless, its influence on the adhesive properties should be checked.
