S-378 Silicone \u0a32\u0a17\u0a3e \u0a0f\u0a1c\u0a70\u0a1f<\/h2>\n

Structure or Component:<\/strong> Polyether-modified polydimethylsiloxane copolymer<\/p>\n

Features and Applications<\/h3>\n

Similar to BYK-378, S-378 is a high-performance, solvent-free silicone surface additive designed to significantly reduce surface tension and enhance both scratch resistance and surface slipperiness. It delivers an excellent hand feel while notably improving paint atomization and spraying fluidity for smoother application.<\/p>\n

Beyond basic wetting performance, this additive offers superior anti-shrinkage properties and effectively prevents the common “mirror frame” effect in coating finishes. It boasts high compatibility across aqueous, solvent-based, and solvent-free systems, ensuring a defect-free, oil-spot free surface finish. Additionally, it promotes the directional arrangement of matting agents and provides exceptional slip and long-term durability in high-gloss coating systems.<\/p>\n
