TR-TPO-L is an efficient UV photoinitiator with high initiation activity, excellent solubility and photobleaching performance, and is suitable for systems with high requirements for chroma reduction. TR-TPO-L can be used in formulation systems with low yellowing and low odor. TR-TPO-L is widely used in UV coatings, inks and adhesives.

HARDLEN CY-2329 is an adhesion promoter for polyolefins, which is improved the compatibility with other resins and the stability under low temperature. Therefore, the mixed solution does not increase the viscosity, and does not show gelation. The characteristics of HARDLEN CY-2329 are good adhesiveness to PP/EPDM and TPO without treatment, good compatibility to other resins, and good stability under low temperature (-5 degree C).
