REMET Brand colloidal silicas have been specifically designed to meet the needs of the Precision Investment Casting Market.
Remet 1000-Series Binders are slightly opalescent preformulated chemically inert colloidal silicas.
The 1000-Series is comprised of 2 binders:
Binder 1010 – For back-up slurries
Binder 1020 – For primary slurries
The silica in 1000-Series colloidal silicas is amorphous in nature and non-crystalline, both grades have high surface areas, and have negatively charged particles stabilised in a weak solution of sodium hydroxide.
As the REMET 1000-series colloidal silica dries, water evaporated and bonding between the silica and refractory particles begin to occur. These refractory bonds are heat resistant and allow the Caster to successfully make a shell into which molten metal can safely be cast.
The choice of Grade is dependent upon the specific conditions under which it will be used. Your local REMET agent can advise on which grade is best for your purpose.
