Deuteron® SO 500 is a liquid formulation containing fine elastomer particles suspended in a solvent carrier. These elastomer particles are effective in providing a rubber-like tactile sensation to coating films. The dispersion of these fine elastomer particles is designed for formulating soft-feel coatings and is available in various forms, such as water solvents and acrylic functional monomers, offering flexibility in formulation and application.

Product Highlights
  • Deuteron® SO 500 is liquid preparations of fine elastomer particles in a solvent carrier. The used elastomer particles impart a rubber-like feel to any coating film. Depending on the addition level it is possible to achieve pleasant soft touch effects even in extreme hard and brittle systems without compromising the film toughness.
  • The use of Deuteron® SO 500 and its unique soft-feel approach eliminates the need for special soft and elastic resins as it works with almost any given system. This opens up a wide range of formulation freedom to design soft-touch systems with outstanding durability.
  • Deuteron® SO 500 is a easy to use liquids that are suitable for the use in auto dosage units. They are manufactured without any additives such as dispersants.

Application and Dosage Information
  • Deuteron® SO 500 can be used in all solvent- based coating and ink systems. The matting and soft- touch effects are largely independent of the applied film thickness and it is possible to combine Deuteron® SO products with common surface additives such as waxes or other matting agents to impart soft-touch with minimal impact on the overall system performance. Because of the hydroxyl content of the elastomer particles it is possible to crosslink the particles using isocyanates. This ensures a good particle embedding and leads to significantly improved mechanical stability but slightly reduced soft-touch.

The use of Deuteron® SO 500 / SO 510 especially improves performance in:

  • Soft-touch effects independent on the used binders
  • Matting  
  • Good recoatability
  • Excellent mechanical and chemical resistance
  • Temperature stable up to 160 °C
  • Anti-Blocking
  • Insoluble in common solvents
  • Flexibilization


  • 10 - 20 % (calculated on the complete formulation) depending on binder, application and required properties. The optimum dosage depends on the binder system and the desired surface character. It must be determined by own tests for the respective system. Higher addition levels lead to stronger effects and increased flexibility. As
  • Deuteron® SO 500 is highly compatible, even very high dosages up to 70 % can be used to generate extreme effects. For crosslinking with isocyanates, a significantly over-stoichio- metric dosage is recommended.


Deuteron® SO 500 is easy to disperse and can be incorporated using a common high-speed stirrer. It is possible to add Deuteron® SO 500 at any stage of the production process, even post addition to adjust properties at a customer line is possible. Deuteron® SO 500  does not stabilize foam.
