Special-Primer PP 4400 W
Special-Primer PP 4400 W is a water dilutable chlorine-free primer and adhesion promoter based on special modified polypropylene used for polypropylene and polyolefinic blends.
Special-Primer PP 4400 W was developed to solve adhesion problems with critical substrates like polyolefinic plastics and blends.
Special-Primer PP 4400 W as well can directly be used as adhesion promoter by incorporation in adhesives, inks and paints in case of sufficient compatibility or diluted down to approx. 10% solid content as primer.
The primer may be applied by spraying, dipping or printing. We recommend application quantities of 5-30 g/m². To get the optimum, tests should be done individually.
