Adding: Use a two-component dosing and mixing unit to add the adhesive continuously to the adhesive tank of the solvent-free laminator. The adhesive in the tank should be kept as fresh as possible to avoid abnormal viscosity affecting the coating result. Pot life: 858A/Hardener 856B component has a pot lifetime of about 40-50 minutes at 45°C after mixing and shows reliable workability. See Figure 1 below. Laminating conditions: Precise tension control and proper winding procedures prevent delamination, roll head size difference, and film curl. Curing: Cure at 38 - 45℃ for 18-24h for rewinding and slitting. Aluminum foil composite products usually need to be cured at 45℃~50℃ for 36~48 hours, winter AI/CPP structures need to increase the curing time to 48~60 hours. Cleaning: When the machine is shut down for more than 40 minutes, the metering roll position adhesive can no longer be used and the coating unit needs to be cleaned with a solvent/plasticizer mixture (refer to Safety Precautions). The two-roller coating unit also needs to be cleaned and the same cleaning procedure should be carried out at the end of the start-up period.

728 2K Polyurethane Adhesive For Various Film/Film And Film/Metalized Film Laminates good flexibility & Transparency

TDS Weeton 728A 728B EN.pdf   Weeton 728 is a two-component polyurethane adhesive for various film/film and film/metalized film laminates. This product has good flexibility and good transparency, can effectively reduce the characteristics of aluminum transfer, and prevent the phenomenon of tunnel.   Properties Product Name 728 A                                                   728 B Mixing Ratio 20:4(mass ratio) Solids Content 75±2%                                                75±2% Viscosity              2000±500mPa.s (Brookfield LVT Rotor 2 / 30rpm,25 °C)  2000±1000mPa.s (Brookfield LVT Rotor 2 / 30rpm,25 °C) Solvent Ethyl acetate                              Ethyl acetate Flash Point -4°C                                                   -4°C Color Colorless to yellowish    Directions for use Dilution: Suitable solvents are ethyl acetate, and Methylethylketone provided that the water content does not exceed 300 ppm. Do not use aromatic or alcoholic solvents. Preparation of Adhesive Mixture: After having added the right quantity of solvent to 728A and having achieved the required solids 728B has to be stirred into the 728A/solvent mixture. List of Dilution: When the ethyl acetate is used for dilution, to obtain an accurate solid content, it is required to refer to the following solvents. 728A 7 28B Solvent Solid Content Viscosity 20KG 4KG 21.0KG 40% 8-11s 20KG 4KG 27.4KG 35% 7-10s 20KG 4KG 36.0KG 30% 6-9s 20KG 4KG 48.0KG 25% 5-8s Viscosity is based on the average viscosity of the Zahn Cup 3# (25°C)   4.  Pot life: The ready-for-use adhesive in closed containers has a working time of about 8 hours. If the laminating machine doesn’t use adhesive, the retention time shouldn’t be more than 4 hours. Otherwise, the adhesive should be abandoned, or it may result in unstable laminated film. Tropical area (Temperature >28°C + humidity >60%) pot life: Ready-for-use adhesive should be used up within 2 hours.   5. Coating: 728 is suitable for dry film laminating machines with smooth roller or gravure roller. Before mass production, repeated trials should be carried out to determine the fitting roller.   6. Application weight: Depending on the film or foil combination and the end use of the laminate, the adhesive weight may range from 2.0g/m 2 (dry). For printed laminates the weight has to be adjusted accordingly, it should be approx.0.5-1g/m 2 higher than for unprinted films.   7. Dry: The laminating machine should have good air volume, wind speed, wind pressure and the appropriate temperature to avoid residual solvents. Temperature setting generally follows gradient principle (55°C-65°C, 65°C-75°C, 70°C-85°C). Adjust the temperature of the oven according to the performance of the processed products, raw materials, processing technology.   8. Pressure adjustment:  An appropriate increase in laminating temperature and pressure can improve the bonding effect and surface finish of the laminates.   9. Curing: Stored in a curing chamber (45-55°C), the laminates will be ready for cutting in 24h. The curing time should be extended if the laminates are used for bagging.   10. Film properties: The completely cured 728 polyurethane film is transparent, odorless, elastic and aging-resistant.   Product certification 728A/728B are suitable for laminating food packaging materials in accordance with US FDA 175.105 and Chinese GB- 9685. After sizing, the fully cured adhesive material complies with the EU 2002/72/EC and its Supplementary Agreement 2004/19/EC on the restriction of migration of certain substances.   Storage/Transport Storage: 728 have a storage life of 9 months when stored at a cool and dry place in unopened containers. Once opened, containers of 728A/728B should be closed tightly again and the material should be consumed within a short period. Transport: For details please refer to the corresponding safety data sheets.   Packaging specifications 728A:20KG/bucket 728B:4KG/bucket   Notes When using 728 an efficient exhaust hood has to be installed to the coating unit due to safety reasons. The exhaust efficiency has to be checked prior to production by gas analysis for isocyanate concentration in the air. Safety regulations with regard to the handling of isocyanates have to be followed as per the guidelines issued by the International Isocyanates Institute. Please also refer to the local safety instructions as well as our safety data sheet and contact Huitian for analytical support.
