3M Packaging Changes
3M Aerospace have advised us of an upcoming packaging change that will affect a small number of 50ml aerospace paste adhesives manufactured in their Tilloy-Lez-Cambrai, France.
This change involves a new cartridge and nozzle system for small Duo-Pak cartridges (50ml only) to enable better adhesive delivery and ease of use. Please note that unless communicated separately, there are no changes to the chemistry of the impacted materials. The affected products are outlined below:
|Product Id||Product Description||3M Product Number||Mix Ratio|
|P0170015||3M Scotch-Weld EC-7202 B/A Epoxy Adhesive 50ml Duo Pack *IPS 10-04-011-04 *IPS 10-04-003-05||7100099767||2:1|
|P0180067||3M Scotch-Weld EC-7246-2 B/A FST (Fire Smoke Toxicity) Epoxy Adhesive 50ml Cartridge||7000080425||1:1|
|MMMA725650||3M Scotch-Weld EC-7256 B/A Structural Adhesive 50ml Cartridge *IPS 10-04-002-01 Issue 3 *IPS 10-04-003-01 Issue 3 *IPS 10-04-011-01 Issue 4||7100021468||2:1|
|P0190396||3M Scotch-Weld EC-7272 B/A Liquid Shim Adhesive 50ml Cartridge||7100026907||2:1|
|MMM932350M||3M Scotch-Weld EC-9323-2 B/A Epoxy Adhesive Black 50ml Dual Cartridge *201-996-PS/1/E000 Issue 3||7100140744||2:1|
The new cartridge piston includes a double lip seal instead of an O-ring seal which is designed to eliminate leaks which can cause O-rings to swell and degrade over time. In addition, a sealing flange at the rear of the cartridge chamber “locks” the pistons in position for additional protection.
The current cap can be installed backwards on a partially dispensed cartridge, permanently sealing the cartridge shut. This renders the remaining adhesive useless. The new cap is keyed and cannot be installed backwards, so partially consumed cartridges can be saved and used later.
In addition to the above, while 2:1 cartridge systems will remain unaffected, the 1:1 mix ratio product (3M Scotch-Weld EC-7246-2 B/A FST) will be supplied in a slightly smaller volume – 48.5ml.
Finally, when the new packaging is supplied, a new dispensing nozzle will also need to be used. 3M Scotch-Weld EPX Green 1:1 and 2:1 Mixer Nozzle (P0190075) suits a variety of 3M adhesives, and will also suit all new cartridge styles on the aforementioned products. No change to the application gun is necessary, and customers can continue to use the 3M Scotch-Weld EPX Manual Dispenser III Applicator Gun (P0170016).
Due to inventory levels and customer demand, the implementation timing for individual products will vary and is approximate only. Based on current demand, 3M expects that all materials listed in the above list will be fully transitioned to the new cartridge system by August 2021.
