CAPROMER® M (Epsilon-Caprolactone) is a building block for resins such as saturated polyester and unsaturated poly- esters, a modifier for OH-acrylic resins, OH-polyester resins and epoxy resins.  It is also a building block for polymers by ring-opening reactions with polyols or with water.

With a combination of flexibility and hardness (toughness) CAPROMER M can provide special mechanical properties in segmented polymers.

CAPROMER M is suitable for use in coating applications:

• As an intermediate for two-component paints for plastic coatings and automotive repair coatings
• Creating polyurethane dispersions for water-borne and UV-coatings
