Automotive OEM Metal Topcoat and Clearcoat

Clear winners

Polyurethanes provide outstanding automotive clearcoat performance

Automotive coatings used to protect cars must be resistant to weather, sunlight, scratching, chipping, cleaners and chemicals to keep them looking like new.

Automotive topcoats and clearcoats

The most common process (approximately 80 percent) is for a two-coat system in which a clearcloat is applied over a color-imparting basecoat (wet on wet). The remaining 20 percent is a one-coat system in which a pigmented topcoat is applied and baked in a single layer.

Clearcoats and topcoats share similar performance properties. Both topcoats and clearcoats rely on polyurethane technology from Covestro.

Our polyurethanes are ideally suited as automotive clearcoats and topcoats providing:

  • Complete crosslinking even if cured at low temperatures
  • Tunable coating properties such as gloss and flow characteristics
  • Hardness, chip resistance, elasticity and self-healing of minor scratches
  • Good physical, chemical and weather resistance
  • Excellent optical properties
  • Good compatibility with primer surfacers and basecoats
  • Outstanding transparency

We offer a range of solventborne and waterborne one- (1K) and two- (2K) component polyurethane products for high-performance automotive clearcoats and topcoats.

High solids and ultra-high solids Desmodur® and Desmophen® polyisocyanates/polyols are available for the formulation of solventborne 2K polyurethane topcoats.

We offer waterborne Bayhydrol® and Bayhydur® polyols/polyisocyanates for 2K polyurethane clearcoats. Bayhydur® BL and Bayhydrol® dispersions also are available for 1K stoving systems.

All of these products help produce polyurethane-based coatings that meet the automotive industry’s highest performance standards.
