ZJ-EP506
One component epoxy structural adhesive

ZJ-EP506 is a high-performance one component heat cured epoxy adhesive, which is suitable for bonding various metal profiles such as cold rolled steel, galvanized steel, galvanized steel, aluminum magnesium alloy, etc. After curing, it has excellent toughness and mechanical strength, such as high shear strength, T-peel strength, impact peel strength, etc., which can effectively improve the static stiffness and dynamic stiffness of structural components, and increase durability. JS-EP506 can be used for structural bonding of the same or dissimilar metal materials, especially in welding workshops in the automotive manufacturing industry. It can replace or partially replace traditional processes such as welding and riveting in automotive welding workshops

Operation and Safety

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.
? Coating operation
It is recommended to place the 330 mL packaged product in a 40 ° C oven for 20 minutes before manually applying the adhesive using a sleeve type glue gun (manual or pneumatic); It is recommended to use a heatable pneumatic high-pressure plunger pump for barreled products (with a recommended operating temperature of 35-55 ° C and a nozzle temperature not exceeding 60 ° C), which can be applied manually or mechanically, or completely using robot automatic gluing equipment.
matters needing attention:
When ZJ-EP506 two-component polyurethane 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;
? Avoid eye and skin contact; If there is skin contact, immediately rinse with soap and water, and seek medical help.
Before consulting the technical personnel of Zhijiang, it is not allowed to use high chlorine disinfection areas such as swimming pools.
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.
