ÅngstromLink AL-3241 is an encapsulation material designed especially for protection of sensitive photonics assemblies from mechanical shock, thermal shock, dust, and ambient atmosphere.

The product is a two-part room temperature curing system which remains fluid for approximately 4 hours of pot life, and then cures to an elastomer within twenty-four hours at room temperature.

No UV exposure or temperature bake is required to initiate the cure process.

The long pot life of AL-3241 enables the material to fill in voids in a complex assembly and to permit time for any trapped air bubbles to float to the fluid surface and escape.

AL-3241 is supplied in a ready-to-use cartridge which maintains the 10:1 mix ratio automatically as it is dispensed. The product offers a service temperature range of -40°C to +180°C (+260°C for 1 to 2 minutes for soldering operations).
