1.Data
Data JZ2460 GZ2460 Appearance Light yellow or yellow transparent viscous liquid Light yellow or yellow transparent viscous liquid Solid content(%) 60±2 75±2 Viscosity(cps/25℃) 1000±500 1500-1000 Smell No smell No smell Mixing ratio 20 4.5-5.5 2.Recommended technology
- Suitable for dry laminating machines of various speeds
- The recommended ratio of 20:5 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 ≥4g/㎡ (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 (50±5)℃ for at least 12 hours.
4.Storage & Safety
- In a dry, clean, cool environment at 5-30℃, unopened JZ2460/GZ2460 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.
