Kohesi Bond KB 1631 FR-2 is a two component, room temperature curing
epoxy system. This flame retardant epoxy generates low smoke and
contains a non-halogenated filler. Although KB 1631 FR-2 cures hard at
room temperature, the optimum cure schedule would be an overnight
room temperature set-up followed by an addition of heat at 90°C for 2 –
3 hours. KB 1631 FR-2 offers an extensive serviceable temperature range
of -51°C to +90°C, as per UL 94V-0 specification. This product’s exquisite
flow properties makes it ideal for use in potting and encapsulation
applications. In addition to ease of application, KB 1631 FR-2 adheres
well to a wide variety of substrates including metals, ceramics, most
plastics and glass. It provides superior mechanical strength properties
and dimensional stability.

KB 1631 FR-2 offers phenomenal electrical insulation. It also offers
astounding chemical resistance to a variety of fuels, oils, lubricants and
water. Part A has a black color and Part B has an off white color. Also, it
has a very convenient 1:1 mix ratio by weight. With a unique
combination of remarkable performance, ease of use and excellent flame
retardant properties, KB 1631 FR-2 is widely used in electronics ,
microelectronics, aerospace and various OEM applications.
