Solvent is ethyl acetate, acetone, MEK, the water content should be less than 0.03%, the alcohol content should be less than 0.02%, Ethyl acetate is recommended.

Operation Instruction:
Standard mix ratio: EB4050A to EB4050B=10:1, in case of high humidity circumstance, please add more hardener, please choose the proportion according to operation environment.
Dilution: add the solvent to the main agent, stir fully , then add the hardener ,please input all of the hardener , if can not , input some solvent into hardener barrel to wash out , then stir fully again .
Working concentration: 20-40%, best working concentration is 30%
The coating weight: the coated weight on dry base is generally 3.5-4.0g/, but should be changed by the type of film and the weight of the filler .
Evaporation: For evaporating the solvent completely, the drying tunnels should generate enough air speed , air volume and suitable temperature . If the drying device is three sections structure. The temperature from entrance to exit should be 50-60,60-70, 70-80C.degree respectively.
It is recommended to raise the pressure and temperature as possible, but do it without damaging the film. The laminating rollers temperature : shall be set to 50-80 generally. If the laminated plastic films are sensitive to temperature .it shall be set to 50-60, and 70-80 for other films
Curing: The products laminated will be cured at 50-60 C.degree for 48-72 hours.

5. Package
Main agent is 20kg/barrel. Hardener is 2kg/barrel.

6. Storage
EB4050A/B is flammable material, Please keep it in cool and dry place, its quality guarantee is 12 months for major agent and 10months for hardener. Please use up quickly as possible after open the package.
