    Product Description

    Weeton 728 Metalized Film Adhesive , 2K Polyurethane Adhesive Glue / lamination adhesive

    Introduction of 728

    728A in combination with Hardener 728B is a two-component polyurethane adhesive for various film/film and film/metalized filml laminates. This product has good flexibility and good transparency, can effectively reduce the characteristics of aluminum transfer and prevent the phenomenon of tunnel.

    1. 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 8728A/solvent mixture.

     

    2. 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.

    728 A 728B Solvent Solids Content Viscosity
    20KG 4KG 18.6KG 40% 16-19s
    20KG 4KG 24.6KG 35% 13-17s
    20KG 4KG 32.5KG 30% 10-15s
    20KG 4KG 43.6KG 25%

    8-12s

     

    * Viscosity is based on the average viscosity of the Ford cup 4mm/20°C

     

    3. Pot life: The ready-for-use adhesive in closed containers has a working time of about 8 hours. The composite machine is not used up of adhesive, the retention time of more than 2 hours, if more than 2 hours should be abandoned, otherwise it may lead to unstable composite films.

    Tropical area (Temperature >28°C + humidity >60%) pot life: Mixed adhesive should be used up within 2 hours.

     

    4. Coating: 728 adhesive is suitable for dry composite device with smooth light roller or concave roller. Before mass production, repeated trials should be carried out to determine the fit of the wire roller.

     

    5. Pressure adjustment: Appropriate increase in composite temperature and compound roll pressure can improve the bonding effect and surface finish of the composite.

     

    6. Curing: Storage at higher temperatures (40°C-50°C) room, various film/film and film/foil laminates can cutting in 24 hours. Such as curing bag processing should be appropriate to extend the curing time.

     

    7. Film properties: The completely cured 8711 polyurethane film is transparent, odorless, elastic and resistant.

     

    8. Matters needing attention: As the adhesive contains polyisocyanates any contact with skin has to be removed.

     

    9. Others: Film additives-particularly slip agent content in LDPE,MDPE and CPP films-packed goods, printing inks, pre-treatment and coating of films are of significant importance to the end use of the laminates and may affect the performance properties either straight away or later. Therefore, practical laminating tests as well as checks on the laminates are necessary before going into full scale production.
