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).

VYLON GK-880 is a high molecular weight copolyester with high Tg. VYLON GK-880 has a very good heat resistance and chemical resistance. Its main use is in interior can coating.

HARDLEN F-2P is an adhesion promotor for difficult plastic such as polyolefin.
