Temporary Functional Coatings

Temporary functional protection

Polyurethane guards product surfaces, provides easy peel off

Temporary functional coatings are designed to protect high-end items from chemical and mechanical damage, dust, fingerprints and stains during manufacturing, on-site transportation and shipping. Polyurethane (PU) dispersions are uniquely suited for the formulation of these innovative, temporary functional coatings.

The components of many high-end products are manufactured in different locations globally and shipped to a central plant for final assembly and packaging. This creates potential opportunities for damage. Brands want to provide excellent “moments of truth” when consumers unwrap their newly bought devices.

Innovative, waterborne temporary protection PU dispersions from Covestro are used to formulate peelable coatings that, while in place, provide excellent protection. These temporary, functional coatings are ideal for protection of high-end goods during processing and final delivery. They provide:

• Increased process yield and efficiency during part/device production (cost down automation vs. manually applied masking tapes or protective plastic films)

  • Compatibility with a wide variety of application methods, including roller, brush, dipping, spray and screen printing
  • An easy solution for small and complex 3D objects
  • Excellent adhesion to a wide range of substrates, including glass, metal, coating, leather, difficult plastics
  • A waterborne solution with hardly any solvents attacking the surface
  • A unique balance of toughness, elasticity and thermal stability, which can be customized to suit process specific needs
  • Easy removal, no residue

Our one-component (1K) waterborne and UV-curable polyurethane dispersions for temporary peelable coatings are used in many industries, including consumer electronics, automotive, construction and furniture.
