Product Overview

Evonik fumed silica AEROSIL 380 is a hydrophilic fumed silica with excellent properties.

Product Characteristics

High specific surface area: the specific surface area is as high as (380\pm30m^2/g), with strong surface activity and adsorption capacity. Small and uniform particle size: the average particle size of primary particles is about 7nm, which can be uniformly dispersed in various systems, effectively avoiding agglomeration and precipitation. Excellent thickening and thixotropic properties: It can provide excellent thickening and thixotropic properties for products with high specific surface area, and can effectively control the rheology and thixotropy of liquid systems, resins and polymers. High transparency: It has excellent transparency in unsaturated polyester resins, and can satisfy applications with high requirements for transparency after sufficient dispersion.

Product Applications

• Paints and coatings: It can be used as rheological additives and dispersants, playing the role of anti-settling, anti-caking, matting, etc. It can effectively control the rheological properties of coatings, preventing sagging and precipitation, and improving the quality of coatings and the appearance of the effect.
• Silicone Rubber: It is an excellent reinforcing agent for HTV high temperature vulcanized silicone rubber and liquid silicone rubber, which can improve the strength, hardness, abrasion resistance and other properties of silicone rubber, and at the same time, improve its processing performance.
• Adhesives and sealants: used in adhesives and sealants, can improve its rheological properties, increase thixotropy, so that the glue in the application of easy to operate, to prevent flow, improve bonding and sealing effect.
• Printing ink: it can improve the stability and fluidity of ink, prevent pigment settlement, make the ink transfer evenly in the printing process, and improve the printing quality.
• Cable material and unsaturated polyester resin: in cable material can improve the electrical properties and mechanical properties of the material; in unsaturated polyester resin can increase its transparency and stability, improve processing performance.
