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-140 is a high-molecular polyester resin known for its excellent formability, compatibility with other polyester materials, and strong adhesion to metal and PVC surfaces.

VYLON SS-3300 is a co-polyester/amorphous resin primarily designed for can coating applications, both interior and exterior. It boasts excellent retort resistance and food acid resistance, along with good solubility and compatibility with other polyester materials. Additionally, it exhibits strong adhesion to aluminum and tin plate surfaces. Its constituent monomers conform to FDA§175.300 and EU No.10/2011 regulations, although some catalyst components are not listed in the positive lists of these regulations.

HARDLEN DX-530P is an adhesion promotor for difficult plastic such as polyolefin.
