- Product Highlights
- TRAPYLEN® 186 S has a higher chlorine content compared to other TRAYPLEN® grades which results in a good compatibility with other resins and polymers and ex- cellent pigment wetting.
- The cured film has a high gloss and very good chemical and aging resistance.
- The main merit of TRAPYLEN® 186 S is the outstanding adhesion on untreated polypropylene, PP/EPDM thermoplastic rubber and - with limitations - on polyethylene.
- The resistance against fatty oil and grease is limited and must be compensated by using it with low chlorinated TRAPYLEN® grades.
- It is only recommended as a binder resin for screen printing inks and as an adhesion promoter in plastic paints and solvent based contact adhesives on NR/SBR/polychlo-
- roprene basis.

- Typical Properties
- Solubility and Dissolving Process
Dissolving process: Place TRAYPLEN® 186 S and 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. 60 % and filter the solution.
