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.
