一、Overview:
XH-9800 is a one-component moisture-curing solvent-free polyurethane adhesive for lamination packaging, suitable for lamination of paper, transparent film and aluminum foil for printed matter and food packaging. Suitable for conventional paper-plastic composite structures such as PET/paper, OPP/paper, VMPET/paper, etc.
Second, Product features:
1. It has good adhesion to various film substrates and good interlayer composite strength, and is suitable for the composite of various plastic/plastic, paper/plastic and other film structures;
2. According to different regions or climatic conditions, under the heating condition of 70-90℃, it has good fluidity;
3. It has good surface wettability and machinability, and is suitable for composite application of aluminized film material structure;
4. With excellent transparency and gloss, it is suitable for various packaging applications with high requirements on transparency and gloss;

Fourth, curing conditions:
It is necessary to provide the humidity environment required for curing to ensure adequate curing of XH-9800 adhesive. If the relative humidity of the environment is lower than 60% at an ambient temperature of 20°C, a humidification device can be used for production compounding. In a high humidity environment, as long as the moisture does not condense on the surface of the film, it will not affect the normal curing. Paper or cardboard compounding, as the moisture content of 3-5% is sufficient to meet the humidity conditions required for normal curing.
5. Scope of application: It is suitable for general solvent-free composite equipment, and the heating system can heat up to more than 80 °C.
6. Coating amount: 2.5-4.5g/m2 (depending on the post-processing, usage and quality requirements of the composite structure of film and paper)
7. Measuring the temperature of the cot: 80℃; the temperature of the cot: 85℃; the temperature of the composite roller: 35-45℃ (reference value)
Eight, curing temperature: normal temperature (paper-plastic composite); 35-45 ℃ (plastic-plastic, plastic-aluminum structure)
Nine, aging time: 24-48 hours
10. Packing: 200kg/drum
11. Storage: The unopened XH-9800 can be stored for 6 months in a dry and cool place. Unused products must be sealed and stored as soon as possible after opening.
Precautions:
1. Factors such as the printing ink system used, the quality of the film, the additives in the film, especially the slip agent in the PE film, the solvent residue after printing and compounding, etc. will affect the final quality performance of the compound product, which in turn will affect the final quality of the compound product. directly or indirectly affect its performance.
Therefore, due to the complexity of the ink system, it is recommended to test the compatibility between the ink system and the adhesive system in advance.
2. The substrate to be bonded should be clean and dry, free of dust and oil, and must be corona treated, and the surface tension should not be lower than 38 dynes.
3. XH-9800 adhesive contains -NCO group which is very easy to react with water vapor, so it must be sealed and stored as soon as possible during use. In the compounding process, if the machine stops working for more than 15 minutes, the gluing system must be cleaned with solvent. Both ester and ketone solvents can be used to clean the equipment if the unit has a good ventilation explosion protection system. The precautions in the solvent's Material Safety Data Sheet must be followed.
