WANNATE HT-75B

WANNATE® HT-75B (Hexamethylene Diisocyanate-Based Polyisocyanate Solution) is an aliphatic polyisocyanate solution. It consists of 75% HDI trimer and 25% butyl acetate. It is a colorless to pale yellow transparent liquid with an aromatic odor at room temperature.

 

This product belongs to the isocyanurate category.

 

 

As a raw material for polyurethane production, WANNATE® HT-75B is mainly used as a curing agent component for light-stable two-component polyurethane coatings. The coatings exhibit excellent chemical resistance, weatherability, outstanding gloss retention, and superior mechanical properties. Ideal co-reactants include polyacrylates, polyester polyols, and alkyd resins.

 

Coating systems formulated with WANNATE® HT-75B are suitable for air-drying or baking applications, including automotive OEM coatings, automotive refinish, transportation vehicles, industrial products, and plastic finishing.

 

 

Customized packaging is available upon customer request.

 

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.

 

WANNATE® HT-75B can be diluted with ester, ketone, and aromatic solvents such as ethyl acetate, butyl acetate, acetone, methyl ethyl ketone, methyl isobutyl ketone, cyclohexanone, toluene, xylene, etc. It generally has good miscibility with the above solvents, but the storage stability of the prepared solution must be tested. Only urethane-grade solvents (water content < 0.05%, free of reactive groups such as hydroxyl or amino) shall be used. Aliphatic hydrocarbons are not suitable as solvents.

 

Do not dilute WANNATE® HT-75B to a solid content below 40%. Solutions with low binder content may develop turbidity and precipitation after long-term storage.

 

WANNATE® HT-75B is generally compatible with aliphatic polyisocyanates, aromatic polyisocyanates, polyether polyols, and polyacrylates. However, compatibility testing of the formulated solution is required.

 

This product is sensitive to moisture. Storage at elevated temperatures will cause an increase in viscosity and color number. When stored in the original unopened container under cool and dry conditions at 0–30 °C, the shelf life is 9 months.
