Whitepaper Library
NuSil's latest whitepaper, "A Characterization of Ultra Low Outgassing Materials for Aerospace Applications," examines the underlying trends in the satellite industry and how current, allowable levels of outgassing species may not be enough to produce reliable spacecraft. A side-by-side comparison of physical properties for a traditional, low outgassing silicone product vs. an Ultra Low Outgassing™ product demonstrates that physical properties are not adversely affected by a more rigid requirement.
NuSil Technology Europe conducted a study evaluating the effects of Corona treatment on surface energy and the relationship between surface energy and bonding strength. An article, "Corona Surface Treatments and Bonding with Silicone Adhesives," based on this whitepaper appeared in the May issue of Adhesives & Sealants Industry and can be found here.

Silicone Materials Series
Troubleshooting Silicone Materials Series:
Next-Generation Designs
We concluded the Designer Series in the last edition of Industry InSight, so our focus now shifts to troubleshooting specific problems.
Silicone materials can be challenging to use. We've mentioned in the past that curable silicone systems are formulated with specific amounts of reactive species, catalysts, crosslinkers, polymers and inhibitors. The keys to understanding and resolving problems using silicone materials require an understanding and appreciation for each component and how it functions.
This new series will address three common problem areas: lack of curing (inhibition), bubbling, and within-lot variable physical properties. Look for the next edition of InSight, where we will discuss inhibition. In addition, we encourage you to submit your own troubleshooting questions to silicone@nusil.com. We will answer these questions online at www.nusil.com.

New Products & Developments
NuSil Forges New Partnerships, Garners Patent, Unveils Low Outgassing Materials
NuSil recently appointed Huntsman Quimica Brasil Ltda., a subsidiary of Huntsman Corp. (NYSE:HUN), as its exclusive distributor of products for the electronics industry in Brazil. Huntsman Advanced Materials, a supplier of specialty chemicals for the electronics and power industries, will offer NuSil’s silicone-based products and provide technical service to customers in Brazil.
In other news, NuSil was granted a patent for silicone materials with a refractive index higher than 1.545. High refractive index silicones are widely regarded as the next-generation materials for encapsulants and lens materials for high brightness light emitting diodes (HBLEDs).
The company added three low outgassing, dielectric gels to its Electronic Packaging Materials (EPM) line, as well as developed a new product line of Ultra Low Outgassing™ Controlled Volatility Materials for the aerospace industry. EPM-2480, EPM-2481 and EPM-2482 were designed for the encapsulation of chip packages in devices where outgassing-related contamination poses a problem, while the Ultra Low Outgassing materials offer the aerospace industry high elasticity and low modulus over a broad temperature range (-130°C to 260°C).
