SF9360A/B designed for material of helium balloon
01DescriptionSF9360A/SF9360B 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 can withstand 100℃/30min high temperature boiling in structure of plastic to plastic film. After mixing, it has the advantages of long storage time, easy operation and easy cleaning; it will not affect the release of PE film slipping agent, and thus has excellent smoothness. This very high viscosity adhesive is specially
02Performance characteristicsWidely used in laminating of various treated film like PET、PA、AL、BOPP、VMCPP、CPP、LDP etc, specially used in laminating structures of VMNY10/PE18, VMPET7/PE18, AL/PE for helium balloon.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
Recommended Operating Conditions
1 The adhesive should be used up in laminator within 40 minutes after 2-components mixed.
2 SF9360A:SF9360B recommended mix ratio is 100:50 and volume ratio is 100:57.9. The mix ratio can be from 100:40 to 100:60. Please choose the suitable mix ratio according to operation environment.
3 It is recommended to use at 45°C to 50°C. According to different operation requirements, the recommended usage amount is 1.0-2.5g/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.
When the temperature is low in winter, the temperature can be appropriately increased
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 4~8 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.
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
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.
