1. Description
J-31 heat-resistant adhesive is Two-component epoxy paste adhesive cured
in medium temperature. When fully cured the adhesive will have high
temperature resistance, high shear strength. It is suitable for bonding a variety
of heat-resistant parts, and for potting, casting electronical components. It
can be also used for making high temperature Resistance mode and clamping
fixture. And also bonding Magnetic Abrasive and so on.
2. Specification
Main Ingredients: Modified epoxy
Appearance: Part A(modified epoxy) is translucent light yellow viscous liquid
Part B(hardener) is light-yellow solid.
Typical product data:
Temperature -55 degree C 20 degree C 200 degree C
Shear strength, *** > 30.0 >20.0 >5.0
Pulling away from the non-uniform strength, N/cm >300
* Adhesion material is LYl2CZ Aluminum Alloy, the surface was treated by oxidation process
after being polished.
3. Processing
3.1 Pretreatment of joint surface
�Aluminum Alloy (LY12CZ)
After degreasing by Trichlorethylene steam bath, rough the surface by using
80 mesh sandpaper, treat with chromic acid for 10 minutes at 60 ± 5 �for 10
minutes, Clean surface with water and dry at 60 ± 5 � The bonding part
should be used out within eight hours. The surface also can be treated by
chromic acid or phosphoric acid anodized.
�Stainless steel, carbon steel
Blow the surface after degreasing by Trichlorethylene steam bath.
�Graphite products, ceramics, carbon fiber products
Roughing the surface by sandpaper before bonding.
3.2 Refining adhesive
Mixing proportion: A:B=100:40 (by weight)
Preheat Part A to 60 ~ 70 â„?before mix them.
Resin and hardener should be blended until they form a homogeneous mix.
The adhesive should be used out during 8 hours after mixing at room
temperature.
3.3 Adhesive dispensing
On the treated dry and clean bonding surface, spread a thin layer of J-31 on
the surface.
The usage of J-31 is 250~300g/m2. A syringe can be used for dispensing.
