Trapylen® 950 S is a newly developed chlorine-free polyolefin that exhibits exceptional adhesion properties specifically on polyolefin substrates such as polypropylene, PP/EPDM thermoplastic rubbers, and, to a certain extent, polyethylene. Notably, it demonstrates favorable solubility in non-aromatic solvents. This grade finds application as an adhesion promoter in printing inks, adhesives, and paints, serving both as an adhesion booster and a straight primer.

Applications

Using TRAPYLEN® 950 S as a primer dissolve the resin in xylene to 5 % solids. This primer can be applied by spraying, dipping, brushing or printing.

  • Drying conditions: 30 s at 80°C, residual quantity of resin about 3 - 4 g/m².

When using TRAPYLEN® 950 S as adhesion promoter in base coats/pigmented primers, the compatibility of the system must be checked. 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.
