    Directions for use

    • Dilution and Preparation of Adhesive Mixture: After having added the right quantity of solvent to 765A and having achieved the required solid content, 765B has to be stirred into the 765A/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.

    • 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 2 hours. Otherwise, the adhesive should be abandoned, or it may result in unstable composite films.Tropical area (Temperature >28°C + humidity >60%) pot life: Ready-for-use adhesive should be used up within 2 hours.
    • Coating: 765 is suitable for dry film laminating machine with smooth roller or gravure roller. Before mass production, repeated trials should be carried out to determine fitting roller.
    • Coating weight: Depending on the film or foil combination and the end use of the laminate, the coating weight may be above 2.8g/m2 (dry). For printed laminates, the weight has to be adjusted accordingly.
    • Pressure adjustment: An appropriate increase in laminating temperature and pressure can improve the bonding strength and surface finish of the laminates.
    • Curing: Stored in curing chamber (40-50°C), the laminates will be ready for cutting in 72h, at least 48h.
    • Film properties: The completely cured 765A/765B film is transparent, odorless, elastic and aging-resistant.

    Product certification

    765A/765B 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: 765 has a storage life of 12 months when stored at a cool and dry place in unopened containers. Once opened, containers of 765A/765B 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 765 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 guideline 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.

    As the adhesive contains polyisocyanates, any contact with the skin has to be removed.


    Others

    Film particularly the types and content of slip agents in LDPE, MDPE and CPP films, film thickness, packed goods, printing inks, pre-treatment, and film coating are of significant importance to the end use of the laminates and may affect the performance properties either directly or indirectly. Therefore, practical laminating tests as well as checks on the laminates are necessary before going into full scale production.
