Do not use aromatic or alcoholic solvents. Preparation of Adhesive Mixture: After having added the right quantity of solvent to 776A and having achieved t the required solid content, 776B has to be stirred into the 776A solvent mixture. List of Dilution: When the ethyl acetate is used for dilution to obtain an accurate solid content, the amount required should refer to the following table 776A 776B Solvent Solid Content Viscosity 20KG 20KG 26.7 KG 45% 16-18s 20KG 20 KG 35.0 KG 40% 13-15s 20KG 20 KG 45.7 KG 35% 12-13s 20KG 20 KG 60.0 KG 30% 11-12s * 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.

The typical applicable structure is as follows +: OPP/PET/PE OPP/VMPET/PE(CPP) OPP / VMCPP OPP/CPP PA/PE; AI/PE +: Film should get appropriate surface tension by corona treatment *According to the environmental humidity and the film's composite structure, the ratio can be adjusted between 100: 50-70, high temperature and high humidity are appropriate to reduce the 859B content, and the CPP structure is suitable to increase the curing temperature and the amount of glue; Solvent-free composite workshop with air conditioning in the summer, leave the workshop as soon as possible into the drying room, to avoid excessive humidity in the workshop, alternating hot and cold moisture cooling on the surface of the film, resulting in excessive moisture.   Properties   Product Name 859A                                                    859B Component Isocyanate component                     Hydroxyl component Mixing Ratio 100:60* (mass ratio) Solids Content 100%                                                   100% Viscosity          1,000-1,800mPa.s (Brookfield LVT,25°C)       300-900mPa.s (Brookfield LVT, 25°C) Color Colorless to light yellow transparent          Colorless to light yellow transparent Density 1.10±0.05 g/cm 3                                   0.96±0.05 g/cm 3   * Mass ratio changes from 100: 50 to 100: 70 de pending on the humidity and films.   Directions for use Ratio: The standard mass ratio 859A/hardener 859B = 100: 60 can be fine-tuned according to the properties of the product, the ink, the packaging material, and the operating conditions. Mix method: Mix by automatic mixing machine, mix evenly before use. Coating system temperature setting: Recommended mixing and coating operating temperature parameters are shown in the "Typical Use Parameters column" and can be adjusted according to the actual conditions of use. Coating: Suitable for specialized laminating equipment with multi-roll coating systems. Coating weight: Depending on the combination of plastic film or aluminum foil and the end use of the laminated film, the coating amount of the adhesive can range from 1.2 to 2.5 g / m 2 . Usually, for printed film lamination, the coating amount needs to be increased appropriately when the structure is AI/CPP. 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: 859A/Hardener 859B component has a pot life time of about 30-40 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 35 - 45℃ for 12-24h for rewinding and slitting. For three-layer laminates, the second layer of raw material is laminated and then cured for 6-12 hours before the third layer is laminated. Laminates are usually cured at 35- 45℃ for 24-48 hours, Aluminum foil composite products usually need to be cured at 45 ° C ~ 50 ° C for 36 ~ 48 hours, and the Al/CPP structure needs to appropriately increase the curing time of 48~60h in winter. Cleaning: When the machine is shut down for more than 30 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.

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: 859A/859B are recommended to be stored in a cool and dry place, away from sunlight and high temperatures. When unopened it should be stored in the original closed container. The main agent 859A is valid for 12 months and the hardener 859B for 12 months. Open the storage container, after use should be re-covered and sealed, and the rest of the product should be used up within a short period of time.   Transport: Please refer to the relevant MSDS for details.   Packaging specifications 859A:20 KG/bucket, Special requirement 200KG/Drum ; 859B:20 KG/bucket Special requirement 200KG/Drum ;   Notes When using 859A/ hardener 859B an efficient exhaust hood should be installed on the coating unit for safety reasons. The exhaust efficiency has to be checked prior to production by gas analysis for isocyanate concentration in the air. Safety regulations about 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.   Special Note:859B In cold winter, there will be small lumps is a normal phenomenon, before use in the drying room preheating can be melted or in the dosing tank can be melted, which does not affect the use.       Huitian is your reliable partner and satisfies your need for adhesives!
