CAPA for spearhead performance
Automotive
Paints and Coatings

CAPA® monomer is used to modify the performance characteristics of a range of commonly used resin systems including acrylics, polyesters, epoxies and improve the performance of pigment dispersions.  Typically, CAPA® monomer is used to improve the flexibility and toughness of the resin system.

CAPA® liquid polyols can be used to improve flexibility in epoxy resins used in primer systems by OEM. They can also be used to manufacture high performance PU coating for both OEM and refinish applications.

Clear PU decorative coatings for doming and interior applications can be made with CAPA® polyols.

The benefits provided by CAPA® products are:

  • Low viscosity polyols and prepolymers reduce/eliminate solvent and VOC.
  • Low Tg (-60oC) 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.
