Technical Bulletin 54: AEROSIL® Fumed Silica in Unsaturated Polyester Resins and Vinyl Ester Resins  (pdf, 635 KB)

This bulletin is a guide for the use of AEROSIL® Fumed Silica as a thixotrope in unsaturated polyester resin and vinyl ester resin applications such as gelcoats and laminate resins. Topics discussed within include the mechanism of thickening, dispersion methods, and the influence of silica properties such as BET surface area on performance. Some standard guide formulations and basic rheological data are also provided as part of the document.


Technical Bulletin 54: 气相法二氧化硅AEROSIL® 在不饱和聚酯和乙烯基酯树脂中的应用  (pdf, 5.66 MB)

The application of hydrophilic and/or hydrophobic AEROSIL® grades and their advantages in UP and VE resins are portrayed graphically and their rheological properties evaluated. The influence of BET surface area, additive and dispersion methods is compared and the mechanism of thickening and thixotropizing is described. There are also standard formulations for laminating resins and Gelcoats and a brief list of technical terms for reference.
