Typical Features:
l After completely crosslinking reaction, the laminated film is a high molecular polymer film which has good adhesion on various substrates. And it has the advantages of high transparency, odorlessness, elasticity and aging resistance.
l Excellent performance of machining, High speed laminating process,
l Lower coating weight , greatly decline the production cost; without drying section , save the cost of energy; without solvent, save the cost of material
l Inflammable , avoid the risk of fire accident. Without the solvent, be unharmful to the workers .
l Available to operate in Room-temperature , easy to clean
Recommended Operating Conditions
¨ Lamination condition:
Precise tension control and proper winding procedure could avoid delamination, tunneling and curling
¨ Pot Life Static 45 minutes approximately
¨ Dynamic 60 minutes approximately
¨ Dry Coating Weight paper plain side:2.5-3.0gsm; paper rough side:3.0-3.5gsm
¨ Pressure Disc temperature 95℃ -100℃
¨ Conveying Tube Temperature: 95~100℃

¨ Cleaning Solvent Ethyl Acetate
¨ Clean: Once the equipment is stopped (over 60 minutes), the solvent/plasticizer mixture is applied to clean the five coating rollers system(should comply with safety rules). The same cleaning procedure should also be performed when the equipment has completely stopped running.
Note : This adhesive is continuously added to the coating gap by conveying by a metering pump with a round disc pressure head. This pressure disc directly insert in our adhesive drums which is fully-opened at top side drum. Please let us know your pressure disc size which shall conform to inner diameter of round drum
