- Application Information
- Dynasylan® SILBOND® H-4 can be used, as delivered, to make ceramic molds for the Precision Investment Casting industry.
- The degree of hydrolysis and acidity have been optimized for the required reactivity and sufficient storage stability.
- The hydrolysis and condensation has been started during the production of the binder. Through a shift in the pH this process is accelerated. This shift is achieved by addition of fillers, pigments, additive, or through the evaporation of solvent or exposure to atmospheric moisture. The resulting silicic acid gel cures rapidly at ambient temperatures in air. The process of curing can be accelerated through the addition of alkali catalysts.
