The solvent-based two-component polyurethane adhesive is well-suited for laminating metal surfaces with activated PET, VMPET, laser film, rainbow film, and similar materials. It is designed to perform effectively on dry laminating machines operating at various speeds, ensuring reliable adhesion and quality bonds for diverse applications in packaging, insulation, and other industrial uses.
Metal surface-film laminating PU adhesive JZ2160/GZ2160
This solvent-based two-component polyurethane adhesive exhibits strong adhesion to metal coils, ensuring durable bonds.
Composite products laminated with this adhesive are highly resistant to stamping, corrosion, and aging.
Additionally, the adhesive is non-toxic and odorless, making it suitable for applications where cleanliness and safety are paramount, such as in food packaging and medical equipment.

- Suitable for dry laminating machines of various speeds
- The recommended ratio of 20:4 is the conventional ratio. The actual environmental humidity and printing ink have a significant impact on the composite effect. Customers should adjust the amount of curing agent appropriately according to the actual situation.
- When diluting, add the solvent to the main agent according to the required solid content, stir thoroughly, then add the curing agent, and stir evenly before use. Note: The water content of ethyl acetate shall not exceed 0.03%, and the alcohol content shall not exceed 0.02%. When the solvent contains active hydrogen (such as alcohol, amine), side reactions will occur, resulting in a decrease in the effective content of the curing agent. In actual use, the mixing ratio should be adjusted appropriately according to the situation.
- In order to evaporate the solvent in the adhesive layer of the substrate film, the drying efficiency of the drying machine should be improved as much as possible.
3.Amount of adhesive &Curing
- The recommended coating amount is ≥3.5g/㎡ (dry basis). In actual application, customers can increase the coating amount appropriately according to the situation.
- The composite product should be cured in a curing room at (60-70)℃ for at least 72 hours.
4.Storage & Safety
- In a dry, clean, cool environment at 5-30℃, unopened JZ2160/GZ2160 can be stored for 12 months.
- After contact with glue, it should be thoroughly cleaned, including work clothes, protective glasses, masks and gloves stained with glue.
- Be careful! Empty barrels of glue after use also contain hazardous substances. Please handle according to the instructions on the barrel label and do not use these empty barrels without professional cleaning.
- If you need more safety information, please refer to our product safety data sheet.
