| Solution of an acrylic functional, polyester modified polydimethylsiloxane |
 |
Reactive silicone surface additive for solvent-based and solvent-free systems.
The additive orients to the paint surface, reacts via its acrylic function with the binder and is thus fixed at the paint surface.
Due to the acrylic function it is suitable for all UV-reactive systems (i.e., wood and furniture coatings, paper varnishes).
In comparison to conventional non-reactive silicones, it provides more permanent surface properties (such as improved slip, solvent resistance, weather resistance, anti-blocking and less dirt retention) when crosslinked to the paint surface by its reactive groups.
BYK-371 additionally reduces surface tension and consequently improves substrate wetting it improves levelling, orientation of flatting agents and prevents Beard cells.
Improved substrate wetting is demonstrated primarily in UV-curing roller varnishes in UV-curing flow coat systems, BYK-371 stabilizes the curtain.
If this additive is used in paint systems in which the reactive groups are crosslinked into the polymer network, please note the following Before recoating, the surface has to be sanded carefully and uniformly to ensure sufficient adhesion. |
