Biaomei SiFast SF-721 is a high-efficiency leveling agent under Biaomei brand, formulated as polyether-modified polyorganosiloxane, specially developed for solvent-based coating and ink systems. It can significantly reduce the surface tension of the system, has both excellent leveling and spreading properties, strongly improve substrate wetting effect
Excellent leveling and spreading - Outstanding leveling property, uniform spreading, quickly eliminate construction leveling defects
Strong substrate wetting - Improve the wettability of coatings and inks to substrates, reduce surface defects
Excellent resin compatibility - Highly compatible with various organic resins, no compatibility risks, wide adaptability
Significant disease inhibition - Effectively prevent paint defects such as craters, pinholes and craters, ensure flat film formation
Low tension easy construction - Reduce system surface tension, optimize construction fluency, easy to operate
Solvent-based coatings - Suitable for various solvent-based coatings, optimize leveling and wetting, improve paint film flatness and gloss
Printing inks - Used in various solvent-based printing inks, improve leveling, ensure clear and uniform printed patterns
Wood solvent-based coatings - Optimize wood coating leveling, improve substrate wetting, highlight wood texture
Plastic solvent-based coatings - Suitable for plastic substrate coating, enhance wetting, reduce surface defects, improve adhesion
Metal solvent-based coatings - Used for solvent-based coating of metal substrates, inhibit paint defects, ensure film formation quality
