FEATURE AND APPLICATION
* JADEWIN PR25 is an unique UV absorber with excellent absorbtion especially in the UVB-range
* JADEWIN 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
*JADEWIN 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.
* JADEWIN PR25 is recommended for use in PVC, polyesters, PC, polyamides, styrene plastics, EVA copolymers, and cellulosics, particular in Rigid PVC materials.
