FASCAT® 4203 is a dibutyltin oxide catalyst that offers many benefits for aqueous cathodic electrodeposition of polyurethane coatings.
The FASCAT® 4203 catalyst is extensively utilized in the aqueous cathodic electrodeposition process of polyurethane coatings, namely for automotive and industrial applications. It is the pulverized form of FASCAT® 4201. Moreover, this grade provides a consistent dispersion for water-based coating applications, particularly for pigment pastes in blocked isocyanate urethane systems.
