DOW CHEMICAL CO.: Polyurethane Adhesive System
This company has announced the availability of its new Mor-FreeTM L75-173/C-145 solvent-free, 100%-solids polyurethane adhesive system for flexible packaging.
The two-component product is formulated as a lower-cost alternative to adhesives currently on the market for laminating and general-to-medium performance packaging applications. Dow has advised converters seeking to lower production costs for packaging laminations that this fast-curing Mor-Free adhesive can be applied at room temperature, and such laminates can generally be further processed in as little as six hours. Chemical curing typically requires up to five days at ambient temperatures.
New Mor-Free L75-173/C-145 may be run at speeds as high as 1500 feet per minute while maintaining excellent appearance on a range of substrates. It can be used for laminating all polyolefin films, including LDPE to LDPE, OPP to OPP, and OPP to LDPE, as well as nylon, aluminum, polyester, and other packaging substrates. The films may be unprinted or reverse-printed with the appropriate laminating grade inks. A long pot life is also a feature of this adhesive.
