Features & Benefits
- Product Highlights
- TRAPYLEN®113 S 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.
- Compared to other modified chlorinated types it has a higher molecular weight and a narrow molecular weight distribution. Due to reduced content of maleic anhydride this product has good compatibility properties with other binder resins.

- Solubility and Dissolving Process
- Place 1 part of TRAYPLEN® 113 S and 2 parts of solvent into a dissolver and stir the resin to dissolve it by friction. The temperature of the system should be raised to 60 °C and held there for at least 3 hours. After finishing the dissolving process adjust the solids content to e.g. 20 % and filter the solution.
- Using TRAPYLEN® 113 S as a primer dissolve the resin in xylene to 5 % solids. This primer can be applied by spraying, dipping, brushing or printing.
- Product Application
- Using TRAPYLEN® 113 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® 113 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.
- Product Uses
- TRAPYLEN®113 S is used either as a straight primer or as an adhesion promoter for base coats and pigmented primers.
- TRAPYLEN®113 S 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®113 S can also be used in adhesives and flocking agents for door seals.
- TRAPYLEN®113 S is used in industrial applications where PP based plastics are chemically pretreated.
