| Derivative of 2,4-dihydroxy benzophenone |

EFKA-6725 transforms the ultra violet component of the daylight (300 - 400 nm) into harmless heat, thus eliminating the destructive action of UV-light.
EFKA-6725 contains a reactive group that cross-links with the alkyd-resins structure during the oxidative drying.
EFKA-6725 therefore becomes an integral part of the film.
This means:
-long lasting activity because there is no migration and agglomeration of the absorber and no leaching by moisture transfer. Due to the interfacial character of EFKA-6725 it orientates strongly at the film surface thereby reducing the degradation of the pigmented film.
-EFKA-6725 also possesses excellent compatibility with alkyd paints and varnishes. |
