Surface Modifier BYK-329
BYK-329 is a new surface additive that combines excellent leveling properties with good defoaming capabilities. It particularly improves the wettability of the substrate for two-component epoxy floor coatings.
Features • Particularly excellent leveling properties, especially in epoxy systems • Superior defoaming even in thick film systems • High effectiveness with low addition levels • 100% active ingredient; particularly suitable for solvent-free systems
basic information
Thick films, especially solvent-free systems, require efficient additives. Additives not only smooth and level the surface to provide an attractive appearance but also demonstrate good defoaming properties during application and in the final coating. BYK-329 is a newly developed surface additive that combines excellent leveling properties with good defoaming capabilities. Composition: Polyether-modified polydimethylsiloxane General properties: • Active ingredient 100% • Density (20°C): Approximately 0.97 g/ml • Flash point: > 150°C
