Features & Benefits

Features
  • Low viscosity
  • Eliminates moisture in solvent-based 1K and 2K polyurethane coatings
  • Compatible with most polyol and isocyanate components
  • The combination of Additive TI and Additive OF in the formula stabilizes the polyurethane coating (direct contact between Additive TI and Additive OF should be avoided as this could render them ineffective)
  • In pigmented one-component polyurethane formulations, Additive TI should be added to the dispersion phase to remove any water present and then Additive OF should be added in the letdown

Applications & Uses
