SF9160A/SF9160B better in softness and leveling

  • 01Description

    SF9160A/SF9160B is a fast-curing 2-component solvent-free polyurethane adhesive that can be fully cured to form an elastic film with good bonding strength and heat-sealing strength. The curing time is short and the colloid is relatively soft.
  • 02Performance characteristics

    widely used in laminating of various treated film like BOPP﹑CPP﹑LDPE﹑PET﹑PA﹑Al foil and Aluminized film etc.Solvent free, reduce the production cost, avoid the problem of the residual solvent, improve the working environment, effectively reduce the pollution and the risk of fireExcellent performance of machining, High speed laminating process, Lower coating weight , greatly decline the production cost; without drying section , save the cost of energy; without solvent, save the cost of materialIncombustible , avoid the risk of fire accident. Without the solvent, be unharmful to the workers . Available to operate in room-temperature , easy to clean

  • Operating conditions

    Operating conditions

    Recommended Operating Conditions

    1 SF9160A:SF9160B recommended mixed ratio is 100:70 and volume ratio is 100:80.7. The mix proportion can be from 100:60 to 100:80 . Please choose the suitable proportion according to operation environment. As laminating aluminized film, please set mix proportion from 100:80 to 100:85.

    2 The adhesive should be used up in laminator within 40 minutes after 2-components mixed.

    3 SF9160A/SF9160B can be used for most films. The film should be corona treated prior to laminating for better adhesion.

    4 Due to the special nature of the adhesive, it should be mixed with special mixing equipment to improve production efficiency and mixing quality.

    5 It is recommended to use at 30°C to 40°C. According to different operation requirements, the recommended usage amount is 1.0-2.0g/m2

    Please make adjustments   according to the actual situation. For example, when high frictional   coefficient films are required or PE film is required to be relatively thin   in second laminating, the laminating temperature can be properly reduced, and   the cooling roll can be opened if possible. In winter conditions, the cooling   roller can be changed to a heating roller, and then the laminated   aluminumized films or thick PE films can have good leveling properties.

    The special structures have   to be curing for longer time, such as boiling grade, retorting grade, etc.   The actual requirements shall prevail.

    Note: When the temperature is low in winter, the adhesive should be put into the curing room in advance for more than 4 hours. To ensure a suitable operating environment, please pay attention to the environmental temperature and humidity in the summer, the moisture absorption of the film, and solvent residual of the printed film, etc. Otherwise, it is easy to lead the adhesive sticky and other problems, the operating humidity should not exceed 80%. When the humidity is low in winter, the mix ratio should be properly adjusted.

  • Special instructions

    Special Instructions

    When laminating different types of ink or transparent ink film, it is necessary to confirm whether it is suitable


    When laminating PET printed film, confirm whether the appearance meets the requirements or not


    If the contents of the package are corrosive, please confirm and start production


    In actual production, if other types of OCHEM solvent-free adhesive are replaced, the cylinder, pipelines and rollers may not be cleaned. If solvent free adhesives other than OCHEM adhesives are replaced, the user must perform thorough cleaning of the feeding system.


    Please stop using adhesive and then contact us when you find that the adhesive has become turbid or there is agglomeration.
