APPLICATION GUIDELINES
SHIPMENT
This Ablestik product is packed and shipped in dry ice at –80ºC.
Inside every dry ice shipment of Ablestik’s products is a small
packet containing the ABLECUBE. This is a small blue cube
which retains its shape at –40ºC. If the ABLECUBE is exposed to
temperatures higher than –40ºC, the cube will melt. Please check
the state of the ABLECUBE to ensure the integrity of the shipment.
If the ABLECUBE has melted upon Receiving inspection, place
the entire shipment in a –40ºC freezer and contact your Ablestik
Customer Service or Sales Representative.
UNPACKING
Transfer the syringes from the dry ice to a –40ºC freezer without
ANY delays. Freeze-thaw voids will form in the syringes if the
syringes are repeatedly thawed and refrozen.
STORAGE
This Ablestik product must be stored at –40ºC. If stored at these
conditions, ABLEBOND 84-1LMISR4 adhesive may be usable for
up to one (1) year. Alternate storage conditions may be used as
follows:
ADHESIVE APPLICATION
Thawed adhesive should be immediately placed on dispense
equipment for use. If the adhesive is transferred to a final
dispensing reservoir, care must be exercised to avoid entrapment
of contaminants and/or air into the adhesive. Adhesive must be
completely used within the product’s recommended work life of
18 hours. Silver-resin separation may occur if the adhesive is left
out at ambient beyond the recommended work life.
Apply enough adhesive to achieve a 25-50
µm
(1-2 mil) wet
bondline thickness, dispensed with approximately 25% - 50%
filleting on all sides of the die. Alternate dispense amounts may
be used depending on the application requirements. Star or
crossed shaped dispense patterns will yield fewer bondline voids
than the matrix style of dispense pattern.
Contact your Ablestik Technical Service Department for detailed
recommendation on adhesive application, including dispensing.
CURE
This adhesive should be cured in conventional box oven per the
recommended cure condition. Refer to the Cure Process Data
section of the Technical Data Sheet for the recommended cure
cycles.
AVAILABILITY
ABLEBOND
®
adhesives are packaged in syringes or jars per
customer specification. Available package sizes range from 1cc
to 30cc and 1 ounce to 1 pound. For details, refer to the Ablestik
Standard Package Data Set or contact your Customer Service
Representative.
Storage Temp
0ºC to +5ºC
* Jar rolling required
Syringes

-15ºC to -10ºC
The shelf life of the material is only valid when the material has
been stored at the correct storage condition. Incorrect storage
conditions will degrade the performance of the material in both
handling (e.g. dispensing) and final cured properties.
THAWING
Allow the container to reach room temperature before use. After
removing from the freezer, set the syringes to stand vertically while
thawing. Refer to the Syringe Thaw Time chart for the thaw time
recommendation.
DO NOT open the container before contents reach ambient
temperature. Any moisture that collects on the thawed container
should be removed prior to opening the container.
DO NOT re-freeze. Once thawed to room temperature, the
adhesive should not be re-frozen.
CAUTION: This product may cause skin irritation in sensitive persons. Avoid skin contact. If contact does occur, wash area immediately with soap and water. Please refer to the Material Safety Data Sheet for more details.
