Attention: The moisture of EAC, no more than 300ppm, is the most suitable solvent for dry lamination. In addition, MEK, TO, ACETONE etc., whose moisture is no more than 300ppm, also can be used as solvent. It will reduce The effective content of hardener when there is active hydrogen, such as alcohol, amine, in the solvent.
Use
Standard Mixing Ratio(weight): EN1175A:EN1175B=20:4
Dilution: Pour the EAC into the EN1175A, and mix absolutely. Add EN1175B before mix entirely.
Coating: The dry basis coating use can be 2.0-3.5g/m2 in order to math the requirement of use purpose, materials and composition. Lamination film, which need hot working or heavily process, should use more adhesive. On the contrary, the use should be less. In addition, the printing film should use more adhesive, too.
Concentration
Normal concentration is 35~50%. The most benefit use concentration of roller coating is around 40%.
Dry
For the volatilization of solvent on the film, please equip the dry machine with strong wind, high speed and applicable temperature. If the dry system consists of three parts, the temperature should be 50~60℃,60~70℃ and 70~80℃ from the entrance to the exit in the order.
Lamination Temperature
50~80℃ is usual. The temperature should be controlled at 50~60℃ if the film is easy affect by the temperature.
Lamination Pressure
At the premise of protecting the film from damage, increase the pressure as high as possible.
Curing
Carry on the cutting process of lamination product at 50±5℃, 24 hours after curing. Extend curing time if there is a process of making bags. The curing needs over 7-10 days when curing in the barn over 20℃.
Package
EN1175A is 20kg/drum, EN1175B is 4kg/drum.
Storage
This product should be stored in a cool and dry place. The validity period of EN1175A is 12 months, and the EN1175B is 10 months.
Attention
1. Have a corona treatment to the film of Polyethylene and Polypropylene is necessary. The surface tension should be more than 52mN/m as large as possible, and the surface tension of PET should be no less than 50mN/m.
2. Environment humidity and moisture in the diluent make an obvious effect on lamination effect. Increase the use of EN1175B when in the High temperature and high humidity season.
3. Remaining adhesive: Do not use remaining adhesive in principle. If there are too much adhesive remained. Saved tightly away from heat and ignition sources after dilution. The remaining adhesive can be used as diluent, which should poured into the new prepared adhesive slowly and can not be used at aluminum foil lamination. Do not use the remaining adhesive if there is the emergence of opaque, translucent or thickening phenomenon.
4. It should be selected before use. The type and concentration of additive make an effect on the strength of adhesive.
5. Do not use this product with other adhesive.
6. Keep tightly in the shadow with the attention of fire and eliminating static electricity.
