Dow Corning SOTEFA (Silicone Optically Transparent Elastomeric Film Adhesive)
January 07, 2014


Dow Corning SOTEFA is a high strength, optically transparent silicone adhesive film designed to provide structural bonding between components made from a variety of material substrates, including glass, engineered plastics and metals.


Application
SOTEFA is most commonly utilized when structural adhesion between components and glass is required in automotive, industrial transportation and construction applications. Originally developed as an engineered interlayer for windshield and glass construction, SOTEFA can also be utilized as an interlayer in next generation “smart glass” applications.


Benefits
  • Superior adhesion and bond strength.
  • High-performance in humid environments.
  • Outstanding resistance to ultraviolet light.
  • Exceptional retention of adhesive strength across a broad temperature range. SOTEFA remains flexible between the operating temperature range of -40° to 130°C (-40° to 266°F).


General Processing Parameters
  • SOTEFA must be applied to a clean surface free of contaminants. Some materials may require the use of adhesion promoters to meet desired properties.
  • SOTEFA must be applied to components with enough force to fully wet out the adhesive. Application pressure of 100 psi is typical, but can vary depending upon component size and geometry. Uniform application at pressure for 5-10 seconds across the mated components is recommended.
  • Addition heat and pressure in an autoclave is recommended to fully activate SOTEFA and to develop optimal adhesion to the substrate. A typical cure cycle for SOTEFA ranges from 20 to 50 minutes at 120°C (248°F) to 140°C (284°F) and 190-225 psi.


Shipping, Handling & Shelf Life
  • Components laminated with SOTEFA stored at or below 10°C (50°F) have a minimum 60 day shelf life. SOTEFA can start to cure if exposed to ambient temperature for an extended time.
  • Temperature control during shipment is recommended to maintain shelf life. SOTEFA applied to a component is typically packaged and shipped utilizing Styrofoam containers as dunnage. Blue ice may be utilized to keep temperatures low during transit.
  • Components laminated with SOTEFA are typically shipped on plastic cards. The cards can be recycled to the supplier for re-use.
