Description
Composition: Polyether modified polydimethylsiloxane
Equivalent Product: BYK 333
Silicone Leveling Agent TPD-3333 is used to reduce the surface tension of the coating systems, promote leveling, improve the wettability of the substrates, prevent shrinkage, and improve the surface smoothness and glossiness. It can be used universally in all coatings systems.
Features
- Not affect overcoatability
- Strong generality, can be applicable to various of coating systems
