Trapylen® 822 X is a chemically modified low chlorinated polypropylene with outstanding affinity to polyolefinic plastics such as PP, PP/EPDM-blends and, with limitations to adhesion strength, to PE. TRAPYLEN® 822 X is used either as a straight primer or as an adhesion promoter for base coats and pigmented primers. Its principal use is in paintings/coatings for molded parts and sealing profiles in the automotive industry, such as bumpers, side panels and door seals. TRAPYLEN® can also be used in adhesives and flocking agents for door seals. Furthermore it is used in industrial applications where PP based plastics are chemically pretreated.

Applications

Application: Using TRAPYLEN® 822 X as a primer dilute the resin solution with 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® 822 X 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.
