Dynasylan® sets standards for sophisticated investment casting processes
Dynasylan® ethyl silicates are used as refractory binders for precision foundry.

Advantages of using ethyl silicate as a slurry binder
- Reduced drying time between coats, and hence reduced shelling time
- Possibility to produce particularly intricate shapes
- Possibility to automate the shelling process by standardizing the drying/setting between coats
- Possibility to adjust the shell strength by chemical setting of the coat
- Reduced shelling area
- Relatively cheap air conditioning set-up
The following products are recommended
- Dynasylan® SILBOND® 40 is is an ethylpolysilicate base with a SiO2 content of approx. 40 %
- Dynasylan® SILBOND® Condensed is a precursor used to make hydrolyzed binders
- Dynasylan® AR and Dynasylan® XAR are ready-to-use binders based on ethylpolysilicate and silica sol with
a SiO2 content of approx. 20 %; they are marketed primarily in Europe - A broad portfolio of Dynasylan® SILBOND® ready-to-use binders are marketed primarily in North America

Dynasylan® ethyl silicates enable a relatively cost-efficient installation of air-conditioning systems.
