UV ABSORBER PR-25 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 doesn’t 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 be also used 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. info at hhochem. com
