Plastic coatings: Customizable for broad functionality, aesthetics

No matter what you're coating – from consumer electronics to lawn furniture to tools – plastic coatings using polyurethane (PU) dramatically improve a product’s durability and appearance.

Plastic coating systems customizable for broad functionality

Plastic coatings using PU dispersions create a durable, customized feel that can be tailored to manufacturers’ requirements. Many plastic surfaces are coated, not only for decorative reasons, but also to protect against weathering, scratches and exposure to chemicals.

Plastic coatings most commonly consist of three layers:




  • Primer  to improve adhesion and to level imperfections of the plastic substrate
  • Basecoat  for coloring and effects
  • Topcoat or clearcoat  for coloring and as protective layer against weathering, solvents and scratches

Additionally, soft-touch coating formulations add pleasant, high-quality haptics to plastics.

PU coatings used for plastic applications typically are one-component (1K) or two-component (2K) systems. These systems are available as either solventborne or waterborne.

Covestro solventborne technologies include Desmodur® N aliphatic polyisocyanates and Desmophen® polyesters. 

With our waterborne PU technologies  many surface modifications are possible, including surface structure (optics) and feel (haptics). Additionally, they offer:

  • Good weather protection, including UV resistance
  • High gloss
  • Excellent resistance to aggressive substances
  • Scratch resistance
  • Excellent flexibility, impact resistance
  • Superior environmental etch protection
  • Curable from room temperature to elevated baking conditions
  • Adhesion to a variety of substrates
  • Fast curing
  • Low volatile organic compound (VOC) levels
