* Viscosity is based on the average viscosity of the Ford cup 3# (25°C).
Pot life: The ready-for-use adhesive in closed containers has a working time of about 24 hours. If the laminating machine doesn’t use up adhesive, the retention time shouldn’t be more than 2 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.
Coating: 776 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.
Coating weight: Depending on the film or foil combination and the end use of the laminate, the adhesive weight may range from 2.0-3.5g/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.
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 the 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, and processing technology.
Pressure adjustment: An appropriate increase in laminating temperature and pressure can improve the bonding strength and surface finish of the laminates.
Curing: Stored in a curing chamber (35-45°C) or a similar wild environment, various film/film and film/foil the laminates will be ready for cutting within around 24 h. Nevertheless, the curing time should be extended if the laminates are used for bagging.
Film properties: The completely cured 776A/776B polyurethane film is transparent, odorless, elastic and aging-resistant.
Product certification
776A/776B is 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: 776 has a storage life of 12 months when stored at a cool and dry place in unopened containers. Once opened, containers of 776A/776B 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.

Notes
When using 776 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.

* Viscosity is based on the average viscosity of the Ford cup 3# (25°C).
Pot life: The ready-for-use adhesive in closed containers has a working time of about 24 hours. If the laminating machine doesn’t use up adhesive, the retention time shouldn’t be more than 2 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.
Coating: 776 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.
Coating weight: Depending on the film or foil combination and the end use of the laminate, the adhesive weight may range from 2.0-3.5g/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.
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 the 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, and processing technology.
