Ep3209 Black High temperature resistant epoxy structural adhesive

EP 3209A/B Epoxy adhesive is a room temperature/heat curing resin adhesive. This two-component bonding adhesive is designed for metal bonding, bonding of cube or SMC fiberglass parts, aluminum honeycomb plate splicing and magnetic steel tile bonding of motor products, ceramic film component sealing, internal structure bonding of lithium battery module, soft magnetic unit potting, high temperature sensor potting, etc.

EP 3209A/B epoxy adhesive can cure in both room temperature and heating environment. After thoroughly mixing component A and component B at 100:50 (weight ratio), the product cures within a certain period of time to form protection.

The cured glue has the following properties:

Resistance to moisture, dirt, and other atmospheric components
High strength, excellent adhesion
Good pollution resistance, low surface pretreatment requirements
No solvent, no curing byproducts
Excellent high and low temperature resistance, -50℃-180℃
Transformer oil resistance, low attenuation
It has good adhesion to glass fiber cloth, aluminum and plastic, aluminum and aluminum and steel plate

Gluing: After stirring the A component in the original package, the A and B components are weighed according to the weight ratio of 100:50.
After the vacuum defoaming is stirred evenly, it will be used up within 80 minutes.
The potting device can continue to be vacuumed if necessary, which is conducive to increasing the electrical performance of the device.
Curing conditions: 120℃*2 hour, 40℃*16 hours or 25℃*24 hours.
If you need to use glue filling equipment, please consult our Marketing Department.
Double tube packaging (2:1 volume ratio), directly use the glue gun for sizing, 5-10 cm glue liquid at the front of the mixing tube is squeezed out before normal use.

Components A and B should be kept away from light and heat and sealed (can be transported and stored as non-dangerous goods);

Storage period Component A: 1 year, Component B: 1 year (25℃);

Beyond the validity period, if you need to continue to use, please first test whether it can be cured normally.
As a manufacturer, we would like to share with you what we have learned about the different types of potting compounds and their characteristics.
The potting compounds on the market vary in viscosity, requirements for cure conditions, among other factors. Compounds such as polyurethane, silicone, and epoxy are widely used in a variety of applications.
Silicone Potting Compounds are soft and flexible, silicone potting compounds and encapsulating materials possess a good level of elongation.Silicone potting compound can also withstand a wide range of temperatures. Most silicone materials are able to operate at temperatures between -40°C and 200°C.
Epoxy potting compounds generally perform as a better adhesive, high-temperature resistance, and chemical resistance and have better adhesion to a wide variety of substrates and typically do not need primers.
Polyurethane Potting Compounds generally have better flexibility, elongation, and abrasion resistance.
Acrylic Potting Compounds are UV and heat-hardening materials, with fast hardening, adequate chemical resistance, and clear appearance.
