CAPA^® polyols are used in the manufacture of polyurethane paints and coatings used in demanding applications such as :

Automotive Topcoats for OEM Automotive Repair Paints Aerospace Topcoats High Clarity Decorative Coatings

• 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.
• Good scratch resistance.
• Consistent, controlled reactivity.
• Polar polyester CAPA^® provides good bonding to substrates.
• High clarity, light stable coatings.

• Very good hydrolysis resistance compared with other polyesters.

Tri and tetra functional CAPA^® polyols are utilised as they are unique in polyester chemistry. The ability to make polyfunctional CAPA^® polyols enables the manufacture of coatings with good cross link density hence excellent chemical resistance.
