Product Benefits
  • WANNATE® HT-300 can be used as the hardener component for lightfast two-component polyurethane coatings with high resistance to chemicals and weathering, very good gloss retention and outstanding mechanical properties.
  • Preferred co-reactants are polyacrylates or polyester polyols.
  • The main applications for coatings based on WANNATE® HT-300 are automotive refinishing, transportation, industrial finishing and plastics, especially in high-solids and solvent-free systems.

Applications & Uses

Properties

Physical Form
Solubility Data
  • WANNATE® HT-300 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-300 is not recommended to be thinned to a lower solid content.
  • Prolonged storage of a solution with a lower content may result in turbidity or sedimentation, even gelation.
