Evonik is the inventor of AEROSIL® fumed silica, which is a synthetic fumed silica that is produced by flame hydrolysis. For over 70 years AEROSIL® has proven to enhance performance in many markets and applications. Today Evonik's AEROSIL® portfolio covers a broad range of surface areas, as well as very different surface chemistries. Also, AEROSIL® does not get tired in finding new markets, applications and effects. AEROSIL® is invented to improve.

VERSALINK® are low-reactivity aromatic amines for use in polyurea or polyurea-polyurethane hybrid formulations. They can be liquid-processed at room temperature with monomeric and polymeric MDI or TDI prepolymers as well as other diisocyanates and diisocayanate prepolymers. Pot life values can be controlled and are typically in the range of 1-45 minutes, depending upon the specific VERSALINK® and isocyanate used. VERSALINK® products are specialty polymeric, non-toxic diamines that can be used as curatives and chain extenders. The range consists of varying molecular weights for use in highperformance polyurethane, polyurea and polyurea-hybrid applications. They can be processed as a liquid and incorporated with MDI and TDI/MDI prepolymers to improve final performance properties. Formulations using our VERSALINK® curatives combine the high performance of polyurea with the ease of application due to the extended pot-life and application time
