Product Options

Size:

Luminar SI-HARD is a rigidizing, hardening liquid silica coating.  This coating is an alkaline, aqueous dispersion of colloidal silica at 50% concentration. It is used for rigidizing and hardening the surfaces of ceramic textile, papers and blankets. It also is ideal as a coating agent and binder. Luminar SI-HARD is easily applied by brushing, rolling, dipping, sponging or spraying. Coverage depends upon the desired hardness.  Drying of treated parts can typically accomplished at temperatures of 150°C for one hour.  Luminar SI-HARD should be stored at temperatures between 5°C (41°F) and 32°C (90°F) to prevent irreversible precipitation of the silica.
