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 UK Technical Sales Manager can recommend the proper grade to meet your specific requirements.
