UV ABSORBERHOSORB UV PR**5 exhibits excellent absorbtion especially in the UVB-range. It is colorless and even in high concentration in the resin does not lead to any discoloration. It doesnt form colored complexes with metal ions. Recommended for use in PVC, polyesters, PC, polyamides, styrene plastics, EVA copolymers, and cellulosics, particular in rigid PVC materials. 
 
It can bealsoused in solventborne coatings and general industrial coatings where stabilization requirements remain moderate.It is particularly recommended for UV cured systems and clear coats where colour neutrality is essential.
