GENERAL INFORMATION
For safe handling information on this product, consult the Safety
Data Sheet, (SDS).
DIRECTIONS FOR USE
1. Certain resins and hardeners are prone to crystallization. If
crystallization does occur, warm the contents of the shipping
container to 50 to 60ºC until all crystals have dissolved. Shipping
container must be loosely covered during the warming stage to
prevent any pressure build-up.
2. Allow contents to cool to room temperature before continuing.
3. Complete cleaning of the substrates should be performed to
remove contamination such as oxide layers, dust, moisture, salt
and oils which can cause poor adhesion or corrosion in a bonded
part.
4. Some separation of components is common during shipping and
storage. For this reason, it is recommended that the contents of
the shipping container be thoroughly mixed prior to use.
5. Power mixing is preferred to ensure a homogeneous product.
6. Accurately weigh resin and hardener into a clean container in the
recommended ratio. Weighing apparatus having an accuracy in
proportion to the amounts being weighed should be used.
7. Blend components by hand, using a kneading motion, for 2 to 3
minutes and scrape the bottom and sides of the mixing container
frequently to produce a uniform mixture.
8. If possible, power mix for an additional 2 to 3 minutes. Avoid high
mixing speeds. This can entrap excessive amounts of air. It can
also cause overheating of the mixture, resulting in reduced
working life.
9. To ensure a void-free embedment, vacuum deairing or
degassing should be performed to remove any entrapped air
introduced during the mixing operation.
10. Vacuum deair mixture at 1 to 5mm mercury. The foam will rise
several times the liquid height and then subside.
11. Continue vacuum deairing until most of the bubbling has ceased.
This usually takes 3 to 10 minutes.
12. To facilitate deairing in difficult to deair materials, add 1 to 3
drops of an air release agent, such as ANTIFOAM 88 into 100
gram of mixture.
13. Gentle warming will also help, but pot life will be shortened.
14. Pour mixture into cavity or mold.
15. Gentle warming of the mold or assembly reduces the viscosity.
This improves the flow of the material into the unit having
intricate shapes or tightly packed coils or components.
16. Further vacuum deairing in the mold may be required for critical
applications.
Storage
Store product in the unopened container in a dry location. Storage
information may be indicated on the product container labeling.
Optimal Storage : 18 to 25 °C
Material removed from containers may be contaminated during use.
Do not return product to the original container. Henkel Corporation
cannot assume responsibility for product which has been contaminated
or stored under conditions other than those previously indicated. If
additional information is required, please contact your local Technical
Service Center or Customer Service Representative.
