    Lamiantion Polyurethane Flexible Packaging Adhesives 100 / 50 Mixing Rate

    Lamiantion Polyurethane Flexible Packaging Adhesives 100 / 50 Mixing Rate 0

    829 has been developed for the laminating of transparent and metallized films as well as aluminum foil for food packaging.829 is a product with low viscosity, good wettability.
    Typical applicable structures are as follows +:
    OPP (PET) // met. CPP
    BOPP // met. CPP (met. PET) // PE
    OPP (PET) // CPP (PE)
    Ny // LLDPE (CPP)
    PET (OPP) // PE (CPP)
    +: Film should get appropriate surface tension by corona treatment.

    * Mass ratio changes from 100 : 50 to 100 : 60 depending on the humidity and films.

    • Directions for Use

    1. Mix Ratio: 100 parts of 829A with 50 parts of hardener 829B.

    2. Coating: 829 is applied on special laminating machines with multi roller application system.

    3. Coating Weight: Depending on the film or foil combination and the end use of the laminate, the adhesive weight may range from 1.2 – 2.5 g/m² (dry). For printed laminates the weight has to be adjusted accordingly.

    4. Pot Life: The pot life of mixed 829 at 50°C is 40min with excellent operability. 

    5. Laminating conditions: Precise web tension control together with a suitable winding program avoids delamination as well as telescoping and curling effects.

    6. Cleaning: In case of a machine stop (for more than 30 minutes) the coating unit has to be cleaned with solvent/plasticizer-mixture and the mixing hose should be cleaned. The same cleaning procedure has to follow at the end of the run.

    7. Curing: The laminates may be rewound and slit after 1-2 days at 35-45°C. Manufacture of triplex laminates is possible 12 hours after duplex production. Complete curing will be achieved after 24 hours at 25-45°C or 3-5 days at room temperature.

    Pot life: over 30min (mixed)
    Application weight: 1.2-2.5g/ m2
    Coating temperature: 53°C
    Coating speed: 300-450m/min
    Curing time: 40°C/24–48h(50-90%RH)

    • Product Certification

    829 complies with FDA175.105

    • Storage

    829 has a shelf life of 9 months when stored at a cool and dry place in unopened containers. Once opened, containers of 829 should be sealed tightly again and the product should be consumed within a short period.

    • Packing Specification

    829A: 20kg/bucket
    829B: 20kg/bucket

    • Notes

    When using 829 an efficient exhaustion hood has to be fitted to the coating unit due to safety reasons. The exhaust efficiency has to be checked prior to production by gas analysis for isocyanates concentration in the air. Safety regulations with regard to handling of isocyanates have to be followed as per the guide line 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.

    • Others

    Film additives - particularly slip additives - in packed goods, printing inks, pre-treatment and coating of films are significant to the end use of the laminates and may affect the performance properties either straight away or later.

    Laminates of high slip containing films, EVA films, CPA films and white pigmented PE films bear the risk of migration of monomeric MDI. This can cause negative influences on the filling good and may lead to antiseal effects. Therefore, practical laminating tests as well as proper checks on the laminates are necessary before going into full scale production.
