Optically Clear, Highly Flexible Epoxy

Master Bond's Polymer System EP37-3FLF is an optically clear, twocomponent epoxy with resistance to cryogenic temperatures and severe thermalcycling. Its low exotherm also makes it useful for potting, encapsulating andcasting systems, especially where wider cross section thicknesses arespecified. Its combination of properties allows it to cure without stressingelectronic components.

Serviceable over the range of 4K to 250F,EP37-3FLF cures at room temperature in 2 to 3 days or faster at elevatedtemperatures. This epoxy offers a non-critical 1 to 1 mix ratio by weight orvolume, and a low mixed viscosity of 1,400 to 1,500 cps. Users can work with a100 g mass of the adhesive at room temperature for up to 90 mins.

EP37-3FLF has a bond shear strength exceeding2,000 psi and a T-peel strength of 25 pli. This flexible epoxy has an elongationof 180 percent and electrical insulation properties with a volume resistivityof 1x1014 ohm-cm. It bonds to a variety of substrates including metals, glass,ceramics, rubbers and many plastics and is widely used in the optical,electrical, electronic, computer and OEM industries.

EP37-3FLF is sold in pint, quart, gallon and 5gallon container kits and has a 6 month shelf life if unopened and stored atroom temperature.
