- Product Highlights
- TRAPYLEN® 187 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® 187 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/polychloroprene basis.

- Place TRAYPLEN® 187 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 the desired concentration and filter the solution.
