Applications & Uses

Properties

Physical Form
Solubility Data
  • Wannate® HB-75BX 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® HB-75BX is not recommended to thin to a lower solid content.
  • Prolonged storage of a solution with a lower content may result in turbidity and sedimentation, even condensation.
