Colloidal Silica Binders
REMASOL® Colloidal Silica binders are aqueous colloidal dispersions of silica particles. The silica particles in REMASOL® are non-crystalline, have a high specific surface area (One gram of REMASOL® colloidal silica has a surface area of between 100 and 400 square meters!), and are negatively charged particles which have been stabilized with sodium hydroxide.
REMASOL® Colloidal Silica’s have been specifically designed to meet the needs of the investment caster, for use as a primary or back up coat.
Remet supply REMASOL® binders in two particle sizes:
- 8 – 9 millimicron
- 14 millimicron
The choice of REMASOL® grade is dependent upon the specific conditions under which it is to be used: refractory flours(s), processing conditions, alloy(s) being cast, etc. Your Remet Technical Sales Manager can recommend the proper grade to meet your specific requirements.
