  • Special instructions

    Special Instructions

    1. The LDPE and CPP films must be corona-treated with a surface tension greater than 38 mN/m. The PA film must be double-corona treated as an intermediate layer. The surface tension must not be less than 52 mN/m; the surface tension of the PET film must not be Less than 52 mN/m.

    2. The temperature and humidity of the environment have a great influence on the time for storing the configured adhesive. It is recommended to arrange the adhesive in small quantities for a few times in high temperature and high humidity weather to avoid waste.

    3. During the laminating processing, care must be taken to check and control the viscosity.

    4. Residual adhesive: The remaining adhesive cannot be used in principle. If the amount of residual liquid is excessive, it shall be sealed and stored in cool place after dilution, which could be used as diluent for operation in next day, and a small amount shall be little by little added to the newly prepared adhesive solution. It cannot be used any more, if it appears cloudy, translucent or thickened.

    5. The concentration and additives in the film have an influence on the bonding strength of the laminated film and must be selected before use.

    6. Do not mix this product with other adhesives. If necessary, please consult our technical department.

    7. Pay attention to fire prevention and static elimination.
