Silicones & Sealants

Silicone adhesives and sealants create the durable and reliable bonds to various materials like ceramics, metals, glass and plastics, all without needing to use mechanical fasteners or clamps. Many are UL-recognized or on Mil Spec qualified product lists and are offered in a wide range of viscosities and cure chemistries to meet your application requirements. Silicone adhesives and sealants form strong but flexible bonds to help to dampen mechanical stress and vibration created during operation. They perform reliably across wide ranging temperatures, from -45°C to 200°C, and they generally provide exceptional dielectric insulation. Most formulations are either one-part moisture-cure types or one or two-part heat-cure types.
