Trapylen® 6965 W is an adhesion promoter based on chemically modified, low-chlorinated polypropylene dissolved in water. It has outstanding affinity to polyolefinic substrates. It is especially developed to improve surface tension of treated and untreated films, foils, foams and even molded parts of PP, PE, polyolefinic blends, a.o. The increase of wetting properties permits the bonding, printing, flocking and painting of such substrates. TRAPYLEND® 6966 W can be occassionally used as adhesion promoter incorporated in adhesives, inks and paints in case of sufficient compatibility.

Product Uses
  • TRAPYLEN® 6965 W is an adhesion promoter based on chemically modified, low- chlorinated polypropylene dissolved in water.
  • It has outstanding affinity to polyole- finic substrates.
  • It is especially developed to improve surface tension of treated and untreated films, foils, foams and even molded parts of PP, PE, polyolefinic blends, a.o.
  • The increase of wetting properties permits the bonding, printing, flocking and painting of such substrates.
  • TRAPYLEN® 6965 W can be occasionally used as adhesion promoter incorporated in adhesives, inks and paints in case of sufficient compatibility.
Applications

If TRAPYLEN® 6965 W is used as a straight primer for plastics dilute it down to 10 % solids, eventually add e.g. coalescence agents, wetting agents and rheological additives to the dilution. This primer can be applied by spraying, dipping, brushing or printing.

  • Drying conditions: 60 s at 80 °C (100 °C).
  • Residual quantity: 3 - 4 g/m².

When using TRAPYLEN® 6965 W as adhesion promoter in base coats/pigmented primers, the compatibility of the system must be checked. Recommended dosage of TRAPYLEN®6965 W: about 10% of 100% formula. The resulting base coat can be applied by spraying, dipping, brushing or printing if the system allows it.

  • Drying conditions: Usually 30 min at 80 °C.
  • Residual quantity: about 15 g/m².
