An Epoxy that Withstands Cryogenic Conditions
Fri, 04/01/2011 - 6:49am
Master Bond has developed the EP37-3FLF polymer system for demanding applications in which highly flexible, impact-resistant bonds are required. This optically clear, 2-component epoxy is also highlighted by:
- Optimal resistance to cryogenic temperatures and severe thermal cycling.
- Low exotherm, making it ideal for a potting, encapsulating and casting system, especially where wider cross section thicknesses are specified.
- The power to cure without stressing delicate electronic components.
- Operational temperatures from 4 K to 250°F.
- The ability to cure at room temperature in 2 to 3 days or faster at elevated temperatures.
- A convenient 1-to-1 mix ratio by weight or volume.
- A low mixed viscosity of 1,400 to 1,500 CPS.
- A bond shear strength that exceeds 2,000 PSI and a T-peel strength of 25 PLI.
- An elongation of 180 percent and excellent electrical insulation properties.
- The flexibility to bond well to a variety of substrates, including metals, glass, ceramics, rubbers and many plastics.
