Properties

Physical Form
Solubility Data
  • WANNATE® TT-350B 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).
  • WANNATE® TT-350B is not recommended to thin to a lower solid content.

Regulatory & Compliance
