 |
| Polyether modified hydroxyfunctional poly-dimethyl-siloxane |
 |
Highly effective silicone surface additive to provide good substrate wetting of critical substrates and good anti-crater performance by reduction of surface tension of the coatings.
It also increases surface slip along with scratch resistance and anti-blocking.
BYK-308 corresponds to the application properties of BYK-307.
The effective substance of BYK-308 is listed in title 21 CFR "Defoaming agents used in the manufacture of paper and paperboard". |
