Description
Product Application
WANNATE® HB-75MX (hexamethylene diisocyanate-based biuret polyisocyanate solution) is an aliphatic polyisocyanate. It consists of 75% HDI biuret, 12.5% propylene glycol methyl ether acetate, and 12.5% xylene. It is a colorless or light yellow transparent liquid at room temperature with a slight pungent odor.
This product belongs to the polyisocyanate category:
| Equivalent Weight | ~255 |
| Density (25°C) | ~1.07 g/cm³ |
WANNATE® HB-75MX is mainly used as a curing agent component for light-resistant two-component polyurethane coatings. The coatings exhibit excellent chemical resistance, weatherability, outstanding gloss retention, and superior mechanical properties.
Coating systems formulated with WANNATE® HB-75MX are suitable for air-drying or baking curing, and are applied in automotive original equipment manufacturing (OEM), automotive refinishing, transportation vehicles, industrial product and plastic finishing, metal anti-corrosion, engineering machinery, bridges and other heavy-duty anti-corrosion fields.

Storage and Handling Precautions
Mass fraction of HDI monomer: < 0.5% Store in a cool, dry and well-ventilated warehouse. Keep away from fire and heat sources. Keep containers tightly sealed. Store separately from oxidizing agents, acids, alkalis, alcohols and food chemicals, and avoid mixed storage.
WANNATE® HB-75MX can be diluted with ester solvents, ketone solvents and aromatic hydrocarbon 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. Different storage conditions may result in different storage stability. Only urethane-grade solvents (water content < 0.05%, free of active groups such as hydroxyl or amino groups) shall be used. Aliphatic hydrocarbons are not suitable as solvents.
WANNATE® HB-75MX 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® HB-75MX is generally compatible with aliphatic polyisocyanates, aromatic polyisocyanates, polyether polyols and polyacrylates, but the compatibility of the formulated solution needs to be tested.
Shelf Life
This product is sensitive to moisture. High-temperature storage 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 of the product is 12 months.
