BYK307 Product Description strongly reduce the surface tension of the silicone surface additive chemical composition: polyether-modified polydimethylsiloxane copolymer Typical Properties solvent ------------ Typical Properties - ------ Volatile:> 97% Solubility ------------ oil density -------------1.03g/cm3 (kg/m3 ) content -------------- 100 (%) effective substance content ---------- 97 (%) Recommended Levels% additive (as supplied) based upon total Formulations :0.01-0 .15% BYK307 adding methods and processing guidance can be at any stage in the production process, to join, and can also be added after. Order to facilitate the join (especially BYK-307 and BYK-333) can be diluted with a solvent with a suitable auxiliaries. Application: solvent-based systems, solvent-free systems, aqueous systems function of these additives can dramatically reduce the surface tension of the coating system, especially improve substrate wetting and avoid cratering. At the same time, enhance surface smoothness and gloss. Comparison to silicone oils these additives are "user security", but before the large-scale use, through a series of experiments to confirm whether these additives to stabilize the foam. Recoatability and cratering tendency addition needs assessment. The nature of the features and advantages of BYK-307 and BYK-306 similar. Solvent-free, it is suitable for applications requiring solvent-free additives or need to use a special solvent system. Packaging: 25 kg / barrel
