3. Cure Cycle:

A. General

The tack, flow, expansion, and cure initiation temperature for AF 3028 and

AF 3028 FR is a time-temperature relationship and depends upon the rate of

heat input.

Normally, the adhesive will begin to cure when a temperature of 225°F

(107°C) is reached. The rate of heat input affects the degree of expansion.

A minimum cure temperature for 230°F (110°C) is suggested to effect a

useful cure in reasonable length of time (approximately 90 minutes).

Full or partial vacuum applied during cure will cause excessive expansion of

AF 3028 and AF 3028 FR.

Storage and Handling

Storage at 0°F (-18°C) or below is suggested for AF 3028 and AF 3028 FR to obtain

maximum shelf life.

Care must be taken when handling the adhesive at low temperatures because it can

easily crack. Warm the adhesive to ambient conditions in the sealed package to

prevent moisture condensation on the adhesive surface.

3M Standard shelf life of AF 3028 and AF 3028 FR is 6 months from date of

shipment from 3M when stored at 0°F (-18°C) or lower.
