Specialty Coatings and Polyurethane Binders

A specialty coating is a formulation, not a commodity. The binder decides how the coating behaves: adhesion to the substrate, gloss, flexibility, resistance to heat and rub, and how it survives the converting step that follows.

Patton Coating produces specialty coating systems and the polyurethane binders used in them, including grades specified for heat resistance and grades developed for ink and lacquer applications.

What the binder controls

• Adhesion to treated PE, PP, PET, metallised film and foil.
• Film formation after the solvent leaves — the difference between gloss and a matt, under-bound surface.
• Flexibility through folding, forming and filling.
• Heat resistance for heat-seal lacquers and hot-fill structures.
• Compatibility with pigments, additives and the solvent system.

Coating types in the range

Heat-seal and protective lacquers, print primers and binders for flexographic and gravure systems. Each is supplied against a defined application rather than as a universal product, because a coating that performs on PET may fail on untreated PP.

Custom formulation and OEM supply

Specialty coatings are supplied as standard grades and as custom formulations agreed against the customer's specification. Custom work is quoted after the brief, not before: substrate, application weight, drying conditions and the performance requirement all change the formulation.

Documentation

Data sheets state solids, viscosity, application weight and drying or cure conditions per grade. Certificates of analysis ship with the batch, and food-contact statements are issued against the destination market.
