Dynasylan® SILBOND® 40-HF

Dynasylan® SILBOND® 40-HF by Evonik is ethyl polysilicate. It is a concentrated form of available silica with a flash point above 100°F (38°C), classifying it as a combustible liquid. It is a partially hydrolyzed mixture of monomers, dimers, trimers, and higher polymers. It is hydrolyzed in water and miscible with organic solvents. Dynasylan® SILBOND® 40-HF is used in the manufacture of less concentrated, more highly hydrolyzed binders.
