Specialty Adhesive Manufacturer and Supplier
Two-component polyurethane adhesives for laminating film, foil and metallised structures where a general-purpose adhesive is not enough.
A specialty adhesive is specified where a general-purpose product would fail: a retort fill, an aggressive product, a difficult substrate, or a line running faster than the adhesive can tolerate.
Patton Coating supplies specialty polyurethane adhesives for flexible packaging lamination, including solvent-based systems for conventional dry lamination and solvent-free systems for lines running without solvent recovery.
Where specialty adhesives are needed
- Retort and pasteurised packs — the adhesive has to hold through steam at temperature.
- Aggressive fills — high acid, high fat or products with solvents that attack a standard bond.
- Difficult substrates — metallised film, foil, untreated or lightly treated PE and PP.
- High line speed — where wet-out and green bond have to build faster than a standard grade allows.
- Low coat weight — thin adhesive films on thin webs, where coat weight control decides the bond.
The three variables that decide the grade
Structure, fill and line. Everything else — coat weight, cure schedule, mix ratio — follows from those three. An enquiry that states only "PU adhesive for PET//PE" cannot be answered properly, because several grades fit that description and only one will hold through the fill.
Supply and documentation
Specialty adhesives ship with a technical data sheet per grade, covering mix ratio, pot life, working viscosity and cure schedule, plus a certificate of analysis for the batch. Migration and food-contact statements are issued against the end market on request.
Wholesale, OEM and private label
Supply is structured for converters, distributors and brand owners: standard grades under the Patton Coating label, or private-label packing against an agreed specification. Volume, packing and destination are quoted together because the three are linked.

Questions buyers ask
Specialty Adhesives: common questions
When is a specialty adhesive needed instead of a standard laminating adhesive?
When the bond has to survive something a general-purpose grade cannot: retort or pasteurisation, an aggressive fill, a difficult substrate such as metallised film or foil, or a line speed the adhesive cannot wet out at.
What information is needed to propose a grade?
The structure (for example PET//PE or PET//AL//PE), the fill and process, the coat weight you run today and the line speed. With those four the grade and its data sheet are confirmed in writing.
Are the adhesives supplied for OEM and private label?
Yes — standard grades under the Patton Coating label, or packed and labelled against an agreed specification. Volume, packing and destination are quoted together.
Not sure which grade fits the structure?
Send the film combination, the fill and the line speed.
