Selecting Fillers and Extenders for Adhesives and Sealants

Silica Silica is also often used as an extender in adhesive formulations. Similar to calcium carbonate, silica is an abundant mineral found in crystalline form (quartz) and amorphous form (diatomaceous silica). Diatomaceous silica is used more extensively than quartz because it is a softer material providing less machining and abrasive problems.
