The demands on new and innovative plastics, which by nature cannot meet these requirements, are constantly increasing. By adding certain mineral fillers, the behavior of the plastic can be modified and customized. A clever combination of polymer and fillers often offers a technically and economically viable solution in a wide range of modern applications. High-performance fillers play a prominent role in the production of thermoset plastics. The high demands placed on thermosets, such as high strength and high temperature resistance, can only be met by functional fillers. In addition, their use in the finished parts leads to optically sophisticated, resistant surfaces. The required mechanical, thermal and electrical characteristics of epoxy resin are largely determined by the selected functional filler. For decades, our fillers have proven themselves in EP resin systems. On the one hand they are used because of their outstanding mechanical properties, on the other hand they make an important economic contribution.

The SILBOND® W 12 EST grade in particular has long been the standard for weather-resistant outdoor applications. Today, SILBOND® quartz powders are also increasingly used for "indoor cast resin parts". Type SILBOND® 126 EST with optimized particle size distribution is recommended for even higher filling levels at the same viscosity.

All our products offer the following properties in epoxy resin
applications:

• improved resistance to weathering and chemicals
• good mechanical strength
• excellent workability
• low thermal expansion
• reduced shrinkage
• high filling levels
