I. Performance features:   

This product adopts multiple functional group monomers and has been polymerized via special synthesis processes. Strong adhesion, good fluidity, excellent operating performance. It is suitable for the combination of PET aluminum coating and cardboard in the production of gold card paper and silver paper for printing and packaging industry. 

II. Technical Indicator:

III. Using process and precautions: 

1. Clean compound machine, pour the glue into the storage tank and use it or add the glue groove directly. The temperature in the drying tunnel is 70-95℃, and the running speed is about 30-50m/min.  

2. The amount of glue is 5-10 grams per square meter, the air humidity is 60% in 25 degrees, and the humidity of paper is 16-20%. 

3. The residual glue on both ends of the rubber roller is rolled over for a long time, it enters the rubber tank after curing with the rubber roller. It may cause irregular size of particles on the compound cardboard. In order to prevent this phenomenon, it is necessary to use the circulating glue to bind the nylon filter cloth of about 200 mesh on the pump head of the circulating pump, so that the glue can be used after filtering. 

4. When the system started for a long time, If there are too much bubbles in the glue tank, it may cause lack of glue at part of rubber roller, we can use the special defoaming agent for spray defoaming or mixing. 

5. In wet weather, the humidity is large and the curing speed of the liquid is slow. It can be adjusted by reducing the speed of the machine or increasing the temperature of the drying tunnel appropriately. 

6. If the four corners of the composite cardboard appear to rise, it may be caused by too high gelatinized amount, resulting in too much shrinkage stress of the adhesive layer. Or due to the high moisture content of the cardboard, it should be properly controlled.
