By laminating various films, laminating adhesives are utilised to create films with novel purposes.
The interfacial adhesion force is determined by three components.
Mechanical fusion (anchor effect): Adhesives penetrate the adherend’s imperfections and solidify there.
Mechanical attachment (anchor effect)
Physical attachment (secondary bond): In a suitably dipolar condition, molecules of adhesives and molecules of adherends can attract one another (intermolecular force). The interactions are layered and glued together by the number of molecules.
Physical ties (secondary bond)
Chemical fusion (primary bond): Covalent or hydrogen bonds are formed between the adherend and the adhesive to achieve adhesion.
The Global Laminating Adhesive Film market accounted for $XX Billion in 2021 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2022 to 2030.
Numerous packaging applications that call for solid bonding holds and rapid cure durations use polyurethane laminating adhesives.
The portfolio of LOCTITE LIOFOL polyurethane laminating adhesives includes, among other things, solvent-free and solvent-based polyurethane adhesives.
Since they may be used on a variety of various substrates, these adhesives are mostly used in the packaging, automobile, and consumer product manufacturing industries.
Wet bond lamination can adhere to more substrates than dry bond lamination, despite the fact that these bonds typically take longer to form.
When attaching two distinct materials and the substrate may be penetrated by the adhesive, wet bond lamination is a viable option.
Because of this, LOCTITE LIOFOL provides a variety of wet bond laminating adhesives with chemistries that are specifically designed to adhere to porous surfaces that are suitable for wet bond lamination.
