SF9110A/SF9180B fast curing time 4-5 hours availabel for slitting

  • 01Description

    SF9110A/SF9180B is a high strength 2-component solvent-free polyurethane adhesive that can be fully cured to form an elastic film with good bonding strength and heat-sealing strength. It is suitable for simple lamination structure, is a non-boiling product, and is suitable for lamination of light packaging. It demands very short curing time (5~6 hours) at normal temperature before slitting
  • 02Performance characteristics

    Widely used in laminating of various treated film like BOPP﹑CPP﹑LDPE﹑VMPET、PET﹑PA﹑and VMCPP etc.It demands very short curing time at normal temperature before slittingExcellent 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

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

    SF9110A/SF9180B can be used for most films. The film should be corona treated prior to laminating for better adhesion

    SF9110A:SF9180B recommended weight mix ratio is 100:65 and volume ratio is 100:78. The mix proportion of SF9110A/SF9180B can be from 100:60 to 100:80. Please choose the suitable proportion according to operation environment.

             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 1.0-3.0g/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.

    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.
