Description
Composition: Polyether alkyl modified polydimethylsiloxane
Silicone Leveling Agent TPD-3333A 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. Compared with TPD-3333, it has a better antifoaming performance.
Features
- Not affect overcoatability
- Good antifoaming performance
- Strong generality, can be applicable to various of coating systems
