Two component epoxy potting adhesive
ZJ-EP510 is a two component epoxy adhesive that solidifies to form an elastomer with excellent properties such as aging resistance, vibration fatigue resistance, and low temperature corrosion resistance. ZJ-EP510 not only has adhesive sealing properties for metal substrates, but also is suitable for adhesive sealing of low surface energy substrates such as PVC and PC. ZJ-EP510 meets the requirements of low odor, low VOC emissions, EU ROHS regulations, and UL94 flame retardant V0 requirements. ZJ-EP510 is suitable for machine dispensing and manual mixing operations. ZJ-EP510 is mainly used for insulation, waterproofing, and sealing of small and medium-sized electronic components.

- usage method:
- ? Surface cleaning
- Use gauze or other tools to remove dust, loose materials, oil stains, and surface water stains from the surface of the area that needs to be coated. If there is rust on the area that needs to be coated with glue, first remove it with a metal brush, and then wipe the surface with acetone and alcohol.
- Primer and cleaning agent
- To achieve optimal adhesion performance, corresponding primers and cleaning agents should be used. When applying primer and cleaning agent, it should be ensured that the application is uniform and there is no accumulation of primer or cleaning agent or the surface of the substrate is not covered.
- ? Mixing
- Take out component A and component B in proportion, stir and mix evenly, vacuum to remove bubbles, and pour them onto the product to be sealed during the operation period. If the sealed product is too large, it is recommended to seal it in batches.
- matters needing attention:
- When ZJ-EP510 two-component epoxy structural adhesive is used in immersion applications, it should be fully cured before immersion.
- Wet coating technology is not allowed, and it is recommended not to use solvents, water, cleaning agents, or soap solutions.
- Before consulting the technical personnel of Zhijiang, it is not allowed to use high chlorine disinfection areas such as swimming pools.
- Moisture can have a negative impact on the curing process and final strength, and it is necessary to prevent the main agent and curing agent from getting damp. Keep the packaging sealed and store in a dry place. The surface on which the substrate is bonded must be clean, dry, and free of dust and any grease. Before using this product, the main agent must be stirred evenly. Our company's technical department can provide further detailed information.
- Pre test procedure
- In order to eliminate potential problems in the application site, Zhijiang can sample various materials used for adhesives, pre determine the best adhesive to be used, and develop the best surface treatment method to obtain the best adhesive performance. Please consult the technical personnel of Zhijiang for specific information.
According to customer requirements, we can provide 20 L small barrels and 200 L large barrels for packaging
It is recommended to store in a cool and dry place for a storage period of 6 months;
Incorrect storage conditions can affect product application and performance after curing
