Frequently Asked Questions
Why RTV silicone?
RTV silicones consist of rubber and gel products developed for adhesion, sealing, coating and encapsulation/potting applications. The Si-O backbone of silicones provides inherent excellent temperature performance, both high temperature stability and low temperature flexibility, excellent dielectric properties, and outstanding weatherability resistance. With our long history in Aviation and Aerospace, Momentive's RTV silicones are an excellent choice for many applications.
What is Momentive's quality assurance?
Momentive has outstanding lot traceability. We conduct quality tests on every batch of silicone and can provide a Certificate of Analysis to our customers upon request. This helps our customers reduce cost by avoiding redundant testing. Additionally, Momentive is an ISO certified facility.
Does cured silicone rubber outgas?
Momentive has formulated specialty RTV grades to reduce outgassing substantially when used under extreme conditions, e.g., high temperature and vacuum. General purpose silicones can outgas under these types of conditions. Please contact Momentive Technical assistance for more information.
Do I need to use a primer?
It depends on your application requirements and product choice. For example, one-component RTV products offer primerless adhesion to most substrates, while most two-components do not. Momentive recommends that you test the product in your application before using it.
How can I get Technical Product Data Sheets, samples and MSDS for Momentive materials?
Product Data Sheets and MSDS are available on our web site, www.momentive.com Sample requests are available by contacting a Momentive authorized distributor or contact our service center. See back page for phone numbers.

Superior Products for Avionics
Long-term, reliable protection of sensitive electronic components is essential to many electronic applications today. Increasingly small systems and rising circuit densities have resulted in hotter operating temperatures, and driven demand for high-performance solutions for heat dissipation. Designers confronting these challenges will find a range of solutions from Momentive Performance Materials, Silicones. Our SilCool* family of adhesives and compounds deliver the high-thermal conductivity, thin bond lines, and low thermal resistance required for high performance components. For applications requiring environmental or stress protection, Momentive offers a selection of silicone adhesives/sealants, encapsulants, and potting materials.
Thermally Conductive Silicone Grease Compounds
Momentive's thermally conductive SilCool grease compounds offer excellent thermal conductivity, as well as excellent stability, penetration, temperature resistance, and low bleed. These properties enable SilCool grease compounds to draw heat away from devices, contributing to improved reliability and operational efficiency of electronic components. The combination of processing performance and thermal conductivity that these grease compounds offer makes them good candidates for thermal interface applications in high-performance devices and packages, such as TIM2 applications in CPUs and MPUs.
Thermally Conductive Silicone Adhesives
Momentive Performance Materials developed its family of SilCool thermally conductive adhesives to help deliver thin bond lines, which contribute to low thermal resistance while providing excellent adhesion and reliability. This series of heat-cured, 1-Part adhesives excel in thermal interface applications that demand good structural adhesion. Examples include spreaders and heat generators, and thermal interfaces to heat sinks in TIM2 applications. Additional thermal adhesives from Momentive offer the process convenience of 1-Part condensation cure with moderate heat dissipation. Target applications include board assemblies and sealants in power modules and sensors.

Frequently Asked Questions
Why RTV silicone?
RTV silicones consist of rubber and gel products developed for adhesion, sealing, coating and encapsulation/potting applications. The Si-O backbone of silicones provides inherent excellent temperature performance, both high temperature stability and low temperature flexibility, excellent dielectric properties, and outstanding weatherability resistance. With our long history in Aviation and Aerospace, Momentive's RTV silicones are an excellent choice for many applications.
What is Momentive's quality assurance?
Momentive has outstanding lot traceability. We conduct quality tests on every batch of silicone and can provide a Certificate of Analysis to our customers upon request. This helps our customers reduce cost by avoiding redundant testing. Additionally, Momentive is an ISO certified facility.
Does cured silicone rubber outgas?
Momentive has formulated specialty RTV grades to reduce outgassing substantially when used under extreme conditions, e.g., high temperature and vacuum. General purpose silicones can outgas under these types of conditions. Please contact Momentive Technical assistance for more information.
Do I need to use a primer?
It depends on your application requirements and product choice. For example, one-component RTV products offer primerless adhesion to most substrates, while most two-components do not. Momentive recommends that you test the product in your application before using it.
How can I get Technical Product Data Sheets, samples and MSDS for Momentive materials?
Product Data Sheets and MSDS are available on our web site, www.momentive.com Sample requests are available by contacting a Momentive authorized distributor or contact our service center. See back page for phone numbers.
