SF9180A/SF9180B fast curing and high bond strength

  • 01Description

    SF9180A/SF9180B is a boiling-resistant two-component solvent-free polyurethane adhesive that can be fully cured to form an elastic film with good laminating strength and heat-sealing strength. It demands shorter curing time than other normal adhesives
  • 02Performance characteristics

    12 hours only curing time required for general film to film laminationhigher bond strength than SF9110A/SF9180Bworkable for 100℃ boiling bag applicationWidely used in laminating of various treated film like BOPP﹑CPP﹑LDPE﹑PET﹑PA﹑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 fire Excellent 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

    Viscosity changing with temperature in mixing unit BEFORE lamination(mPa.s)




















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

    SF9180A/SF9180B can be used for most films. The film should be corona treated prior to laminating for better adhesion

    SF9180A:SF9180B recommended mix ratio is 100:60 and volume ratio is 100:69.8. The mix proportion of SF9180A/SF9180B can be from 100:50 to 100:75. As for lamination with aluminum metalized film, please set mix ratio as 100:75.

    It is recommended to use at 30°C to 40°C or room temperature (25℃). According to different operation requirements, the recommended usage amount is 1.0-2.0g/m2, please find following different recommended usage amounts in laminations of different films structures.


    Note: The above is for reference only, please adjust according to the actual situation (film thickness, ink area, temperature and humidity of the workshop, equipment status).

    Laminating Temperature: please find following different recommended operating temperatures  in different processing sections.



    After production, the surface of the device is cleaned with a suitable solvent to prevent it from being hard to clean after curing.

  • 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.
