Organofunctional silanes are essential to achieve the necessary strength at the relatively low content of the binder. Without addition of silanes to foundry resin the binder strength is not sufficient, only the usage of silanes achieves sufficientlevels of mechanical strength.
We have the optimal product for the respective resin system.
The most important effects of Dynasylan® organofunctional silanes in resin-bonded foundry mould materials
- Improvement of initial and final strength
- Reduction in the resin requirement
- Increase in storage stability of the resin
- Elimination of disturbing environmental effects such as moisture
The choice of the right silane for a particular resin system is made on the basis of known structure and empirical testing. A suitable Dynasylan® can be recommended for all different foundry resin processes.
A wide range of binder systems has been developed with Dynasylan® - to suit different resin systems:
- Croning process
- Hot-box process
- No-bake process
- Cold-box process
- Warm-box process
- Ester curing process
