PRODUCT FEATURES AND APPLICATIONS
*  PR25 is an unique UV absorber with excellent absorbtion especially in the UVB-range
*  PR25 is colorless and even in high concentration in the resin does not lead to any discoloration and will not form colored complexes with metal ions as many other UV-absorbers do
*  PR25 can be used in solvent borne coatings and general industrial coatings ,particularly recommended for UV cured systems and clear coats where colour neutrality is essential.
*  PR25 is recommended for use in PVC, polyesters, PC, polyamides, styrene plastics, EVA copolymers, and cellulosics, particular in Rigid PVC materials.
