High Performance Coatings

The low viscosity and high reactivity of CAPA® polyols makes them ideal for use in formulation of high solids or solvent free polyurethane coatings. Of particular interest is that the versatility of CAPA® chemistry enables the manufacture of multi-functional, aliphatic liquid polyester polyols.

Typical applications include:

 
  • Artificial leather coatings
  • Doming compounds
  • Protective aerospace applications
  • Protective coatings for concrete and metal surfaces
  • Flooring and roofing applications
  • OEM and refinish sectors
  
The benefits provided by CAPA® are:



  • Low viscosity polyols and prepolymers reduce/eliminate solvent and VOC.
  • Low Tg gives good low temperature flex properties.
  • Polyester gives excellent solvent, chemical and UV resistance.
  • Highly functional liquid polyols produce flexible cross links and tough coatings.
  • Stable prepolymers.
  • Consistent, controlled reactivity.
  • Polar polyester CAPA® provides good bonding to substrates.
  • High clarity light stable coatings.

  • Very good hydrolysis resistance compared with other polyesters.
