Product Desciption

Description
SF9200A+SF9200B is a high performance two-component solvent-free aromatic polyurethane adhesive specially designed for 121ºC/30min film-to-film retort-resistant packaging, The adhesive has a long storage time after mixing, and is easy to handle and easy to clean; the adhesive does not affect the PE film slip agent precipitation, thereby having excellent smoothness, widely used in laminating of various treated film like BOPP, CPP, LDPE, PET, PA, Aluminum foil and metalized film etc.

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

Item	Temperature ºC	Remark
SF9200A	40~45 ºC	When the temperature is low in winter, the temperature can be appropriately increased
SF9200B	40~45 ºC
Feeding Tube	40 ºC	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.
Transfer Roller	40~45 ºC
Meter Roller	40~45 ºC
Nip Roller	35~45 ºC
Curing Chamber	40~45 ºC
Curing time	>24 hours	The special structures have to be curing for 48~72 hours, 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.

Performance Index
SF9200A/SF9200B (mixed by weight of 100:65~70) is applied to typical flexible packaging structures and is fully cured up to final peeling strength for your reference (N/15mm).

Attentions

1. When laminating different types of ink or transparent ink film, it is necessary to confirm whether it is suitable
2. The LDPE and CPP films must be corona-treated with a surface tension greater than 40 mN/m. The PA film must be double-corona treated as an intermediate layer. The surface tension of the PET film must not be Less than 52 mN/m.
3. When laminating PET printed film, confirm whether the appearance meets the requirements or not with lab test at first
4. If the contents of the package are corrosive, please confirm and start production
5. The temperature and humidity of the environment have a great influence on the time for storing the configured adhesive. It is recommended to arrange the adhesive in small quantities for a few times in high temperature and high humidity weather to avoid waste
6. During the laminating processing, care must be taken to check and control the viscosity.
7. Residual adhesive: The remaining adhesive cannot be used in principle. If the amount of residual liquid is excessive, it shall be sealed and stored in cool place after dilution, which could be used as diluent for operation in next day, and a small amount shall be little by little added to the newly prepared adhesive solution. It cannot be used any more, if it appears cloudy, translucent or thickened.
8. 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.
9. Please stop using adhesive and then contact us when you find that the adhesive has become turbid or there is agglomeration.
