| BYK-W 920 |
 |
| Solution of a salt of unsaturated polyamine amides and acidic polyesters |
 |
BYK-W 920 is used for wetting and dispersing a wide range of the most common fillers in unsaturated polyester resin systems.
It is especially recommended for unsaturated polyester compounds utilising aluminium trihydrate or calcium carbonate as fillers.
It reduces the viscosity of filled unsaturated polyester compound so that a higher filler load is possible.
The use of BYK-W 920 improves the dispersion and shortens the dispersion time of the filler. BYK-W 920 helps to reduce sedimentation. |
