WANNATE® THM-160B is an aliphatic‑aromatic polyisocyanate solution, consisting of 60% HDI‑TDI trimer and 40% n‑butyl acetate solvent. It is a colorless to pale yellow transparent liquid with a fruity odor at room temperature.
Description
Product Application
WANNATE® THM-160B is an aliphatic‑aromatic polyisocyanate solution, consisting of 60% HDI‑TDI trimer and 40% n‑butyl acetate solvent. It is a colorless to pale yellow transparent liquid with a fruity odor at room temperature.
As a raw material for polyurethane production, WANNATE® THM‑160B is mainly used as a curing agent component for two‑component polyurethane wood coatings. The coatings feature fast drying, excellent chemical resistance, mechanical properties, good weatherability and gloss retention. Ideal co‑reactants include polyacrylates, polyester polyols and alkyd resins.

Storage and Handling Precautions
Store in a cool, dry and well‑ventilated warehouse. Keep away from heat, sparks and open flames. Keep containers tightly closed. Store separately from oxidizing agents, acids, alkalis, alcohols and food chemicals, and avoid mixed storage.
Dilute with solvents such as n‑butyl acetate, acetone, methyl ethyl ketone, methyl isobutyl ketone, cyclohexanone, toluene and xylene. It generally has good miscibility with the above solvents, but the storage stability of the prepared solution must be verified. Use urethane‑grade solvents (water content < 0.05%, free of active groups such as hydroxyl or amino groups). Aliphatic hydrocarbons are not suitable as solvents. WANNATE® THM‑160B shall not be diluted to a solid content below 40%; solutions with low binder content may become cloudy and precipitate after long‑term storage.
Compatibility
WANNATE® THM‑160B is generally compatible with aliphatic polyisocyanates, aromatic polyisocyanates, polyether polyols and polyacrylates. Compatibility testing of the formulated solution is recommended.
Shelf Life
The product is sensitive to moisture. The shelf life is 9 months when stored in the original unopened container under cool and dry conditions at 0–30 °C.
