1. AEROSIL® R208 product introduction
Evonik's AEROSIL® series fumed silica is a brand widely recognized by customers in the market. It is widely used in various industry segments due to its excellent thixotropic, reinforcing, thickening and other properties.
As we all know, Evonik AEROSIL® R202 is the best thixotropic agent for polyurethane adhesives. It can accurately adjust the viscosity and thixotropy of the system to meet the needs of construction. Among epoxy adhesive products, Evonik AEROSIL® R202 also has excellent thickening, thixotropic and anti-sag properties, and is especially suitable for formulations in automated sizing processes.
This time I will introduce to you AEROSIL® R208, a high-efficiency thixotropic agent used in adhesives. Compared with the classic product AEROSIL® R202, both have the same treatment agent. R208 has a higher specific surface area and treatment degree, and has excellent viscosity-increasing and thixotropic effects.
