CAPA for spearhead performance
Polyurethane Manufacture
Coatings

There are many applications for polyurethane surface coatings ranging from automotive paints to flexible membranes on water slides in theme parks, with equally diverse specification requirements. Typical end uses are:

   
  • Moisture Cure Sports Floors
  • Moisture Cure Structural Coatings
  • Automotive Refinish Paints
  • Aerospace Coatings
  • High Clarity Decorative Coatings
The benefits provided by CAPA® products 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.
