HARDLEN NZ-1022 is an emulsifier-free, waterborne adhesion promoter designed for polypropylene (PP) substrates. It features a stable waterborne dispersion that is solvent-free, providing excellent adhesion to polypropylene surfaces.

HARDLEN CY-2321P is an adhesion promotor for difficult plastic such as polyolefin.

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).

HARDLEN CY-2121P is an adhesion promoter which is improved the compatibility with other resin and the stability under low temperature.

HARDLEN EW-5250 is designed higher Chlorine content than other EW-series, so it is better wetting performance. Especially it is able to make film on the substrate for lower temperature baking system. EW-series contains emulsifier. Therefore, the storage stability is good.

HARDLEN^® CY-9124P is an adhesion promotor for difficult plastic such as polyolefin.

HARDLEN® PMA-L is widely used as an adhesion promoter to PP substrate. This grade is chlorine-free environmentally friendly type. It has good adhesion to polypropylene substrates and easy to be melted on substrates at low temperature.
