HACKENSACK, N.J., April 1, 2013 — Master Bond’s Super Gel 9, an optically clear, two-component urethane-modified epoxy gel, offers dimensional stability, softness and resilience for applications including the encapsulation of sensitive electronic parts and the sealing of optical components.
The adhesive has an exceptionally low Shore A hardness of about 5-10, making it suitable for retrieving components with a sharp knife or razor blade. It will not shatter during this process and can withstand rigorous thermal cycling and thermal/mechanical shock.
The gel has a 2:1 mix ratio by weight or volume, and a low viscosity and exotherm, enabling it to be cast in sections up to 2 to 3 in. It bonds well to substrates including metals, glass, ceramics and many rubbers and plastics, and has a working life of 7 to 9 h, depending on the mass that is mixed (the smaller the mass, the longer the working life). The service temperature range is –100 to 200 °F.
The gel is available in ½ pints, pints, quarts, gallons, 5-gallon container kits and gun dispensers. The system is used in the aerospace, electronic, optical, electro-optical and other specialty industries.
