Product Benefits
  • WANNATE® HT-500 can be used as a hardener component for lightfast two-component polyurethane coatings. The main applications for coatings based on WANNATE® HT-500 are automotive refinishing, transportation, industrial finishing and plastics.
  • Preferred co-reactants are polyacrylates or polyester polyols. However, the compatibility of the combinations used should always be tested.

Applications & Uses

Properties

Physical Form
Solubility Data
  • WANNATE® HT-500 can be thinned with esters, ketones and aromatic hydrocarbons such as ethyl acetate, butyl acetate, methoxypropylacetate, acetone, methyl ethyl ketone, methyl isobutyl ketone, cyclohexanone, toluene, xylene, solvent naphtha 100 and mixtures thereof.
  • Generally speaking, it has good compatibility with the solvents listed.
  • However, the solutions formed must be tested for their storage stability.
  • Only PU grade solvents should be used (max.0.05% water, absence of reactive groups such as hydroxyl or amino groups).
  • Aliphatic hydrocarbons are unsuitable as solvents. WANNATE® HT-500 is not recommended to be thinned to a lower solid content of 40%.

Storage & Handling

Storage and Shelf Life Conditions
  • Storage in original container.
  • Protect from moisture, heat and foreign material.
  • WANNATE® HT-500 is sensitive to moisture. Storage at higher temperatures may result in increasing of color and viscosity.
  • Prolonged storage of a solution with a lower content may result in turbidity or sedimentation, even gelation.
  • WANNATE® HT-500 is sensitive to moisture and must be stored in tightly sealed container. It can be stored for at least 6 months at temperatures between 0 and 30°C.
