JT-65A/JT-G751ADry Lamination Adhesive
:PSJT-65A
Advantages
The JT-65A/JT-G751A dry lamination adhesive is a multifunctionalbonding product that is especially suitable for food packaging. Itexhibits excellent transparency, superior elasticity, short cure time, nopeculiar smell, high initial bonding strength, good machinability and wettability, while it is also resistant to hightemperature, acid medium, hot medium and ageing phenomenon.
When bondingplastic/plastic, plastic/Al foil, plastic/Al film and other laminates, ourproduct provides high initial and final adhesive strength, and the finishedlaminates could withstand a 30-minute-long 121°C boiling process that is usedfor sterilization. Our dry lamination adhesive also fits well forpackages that will be boiled in water or stored chilled. Aside from the above,this polyester-based chemical is applicablefor diverse high and low speed printing machines.

Calculation Formula for Dry Glue
Cw=KhN, where
Cw is the dry glue amount(g/m2)
K is the correction factor whose typical values are within 0.25-0.17
h is the cell depth of aniloxroll (μm)
N is the solid content of adhesive (%)
Calculation Formula for Diluent
Wx=(Wz×Nz Wg×Ng)/N-(Wz Wg), where
Wx is the weight of diluent (kg)
Wz is the weight of mainagent (kg)
Nz is the solid content ofmain agent (%)
Wg is the weight of curingagent (kg)
Ng is the solid content of curing agent (%)
N is the working concentration after proportioning (%)
Notes
1. The technical suggestions for this are basedon our experience and expertise. They are true and reliable, but not guaranteesbecause the working condition and process flow are not controllable to us.
2. Before commercial production, please check out whether this dry bond laminating adhesive fits for yourequipment and the end product.
3. Due to technological upgrade, the technical data you got may not be thelatest version, and the update will be made without prior notice.
