3. Applying process and precautions
1. Shake the adhesive even and the applying quantity on dry base is generally 1.1-2.1g/m2.
2. It is better to start compounding before complete drying of adhesive before pressing. It's forbidden to start compounding before the glue on the film is dried. Excellent drying effect of high-speed dry laminating machine speed control 140 ~ 200m/min.The temperatures of sectioned drying channels from the entrance to exit shall be controlled at respectively between 80--90°C,90--105°C,85--95°C.The temperature should reach the set temperature before booting. On condition that no damage is caused to the compound, the higher the drying channel temperature, compounding roll temperature and pressure, the better binding force of the compounding product.
3. Place the product in a curing chamber at 50--60°C between 1—12 hours before cutting.
4. The compounding basic materials such as PE,CPP,BOPP,PET,PA and etc need surface processing which PE,BOPP,CPP must be above 38dynes, PET above 50 dynes, PA above 52 dynes.
5. The types and content of film additives may affect the binding power of compounding film, it's better to choose before using. Especially to control the content of slipping agent for it is crucial in film.
6. The product shall not be mixed with other glues. Before using the network cable roller, and glue plate must be clean, and must be strict Limit contact with ethyl acetate, toluene and other solvents, coating porosity in case. It should clean with isopropyl alcohol first, then reoccupy clear Water to clean. As previously used for solvent-based adhesive should be cleaned with ethyl acetate, and then isopropanol Alcohol and other cleaning, then rinse with water, and before Tim glue production.
7. Glue Usually without dilution for dilution may isopropanol: water = 1:1 or ethanol: water = 1:1 dilution.
8. It is required to lift the blade during shutoff and make the adhesive applying roll slowly turn in the adhesive. Different machines, air temperatures or compounding materials may affect the compound quality. It’s necessary to make pilot test under equivalent conditions before batch production.
