Dynasylan® SILBOND® H-18IC is a clear, low-viscosity pre-hydrolyzed ethyl polysilicate binder that has been designed for use in precision investment casting applications. The silica content (as SiO₂) ranges from 18.0% to 19.0%. This binder contains isopropyl alcohol, which makes it well suited for applications in which slower cure is desired.
Typical Applications
Dynasylan® SILBOND® H-18IC can be used, as delivered, to make ceramic molds for the Precision Investment Casting industry. Dynasylan® SILBOND® H-18IC contains isopropyl alcohol, which makes it well suited for applications in which slower cure is desired.
The degree of hydrolysis and acidity have been optimized for the required reactivity and sufficient storage stability.

Benefits at a glance
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.
