LOCTITE LIOFOL CS 7416 can be applied to paper, glassine and treated and untreated coextruded polypropylene films for snack food packaging applications. LOCTITE LIOFOL CS 7416 has been found to be compatible with release lacquers, but release lacquer compatibility should be verified by lab testing prior to use.
- Mixing Data
LOCTITE LIOFOL CS 7416 must be well stirred before use. It may be applied as supplied. If dilution is needed, add small amounts of water.
- Applications Procedure
LOCTITE LIOFOL CS 7416 may be applied by roller coater or direct pattern gravure systems at high speeds.
Application Weight
LOCTITE LIOFOL CS 7416 recommended dry coating weights are 3.0-3.5 lb/ream. Lower coat weights may be used, but seal values will decrease accordingly, and this needs to be fully evaluated by the converter.
Drying Conditions
For optimum results, substrates coated with LOCTITE LIOFOL CS 7416 must be thoroughly dried. An ultimate web temp of 150°F or greater is recommended.
Sealing Conditions
LOCTITE LIOFOL CS 7416 requires 40 psi jaw pressure for best seals. Good seals with adhesive transfer will result at room temperature. Additional heat will improve seals.
Seal Strength
LOCTITE LIOFOL CS 7416 will form excellent bonds when subjected to sufficient pressure. 400 gpi or higher seal values should result when dyne level is >38 dynes.
Clean up
Wet cold seal coatings should be cleaned before they dry using cold water containing soap, detergent or ammonia. Alcohol or acetate may be needed if coating is dried.

Storage & Handling
- Storage Conditions
Store cold seal between 50-95°F (preferably between 60-77°F). If part containers are stored and reused, ensure that lids are tightly secured. Use cold seal on a first-in, first-out basis. Temperature of the cold seal should be greater than 59°F before introduction to the press. If cold seal is cold then it should be conditioned at this temperature for at least 24 hours. If the cold seal is stored for too long at elevated temperature or used at temperatures in excess of 77°F it can suffer from severe phasing and on-machine performance will be poor with excessive foaming and poor stability. Ensure the cold seal is stirred gently before use.
If a container has been stored for several days, it should be stirred with recommended stirrer for minimum of 45 minutes before use. Stirring can continue at a much lower speed once container is in use as a safety measure.
For finished reels, ensure storage temperature is less than 60-85°F to reduce cross contamination of cold seal and release lacquer. Suspend the finished reels on racks to prevent high pressure areas causing blocking of the cold seal. Store slit reels away from direct light and dust. Wrap well in polyethylene and store between 60-85°F/45-60% RH. If stored at lower temperatures and humidity, allow equilibrating in factory conditions for 24 hours before packing. Think carefully about the shipping conditions of the converted reels. Consider using temperature controlled transport depending upon expected conditions during shipping.
