- Product Benefits
- Wannate® HMDI is raw material for polyurethanes.
- Polyurethane resins based on Wannate® HMDI have good mechanical strength.
- They are resistant to abrasion and hydrolysis and retain gloss and physical properties upon weathering.
- A unique feature of Wannate® HMDI is its ability to form optically clear polyurethanes when combined with suitable polyol coreactants.
- Products based on Wannate® HMDI may be useful in coatings for flooring, roofing, maintenance and textile applications as in cast elastomers, potting and encapsulation compounds, optical products, medical products, adhesives and sealants.

Storage & Handling
- Storage and Shelf Life Conditions
- Wannate® HMDI is sensitive to moisture and therefore should be stored in its sealed original containers. Water or moisture in the air reacts with the product and generates pressure.
- If partially filled containers are stored, it is advisable to blanket the liquid surface with dry nitrogen before sealing.
- At approx. 25°C, crystals will generate in Wannate® HMDI and setting on the bottom.
- The product should therefore be heated to 40 - 50°C and homogenized before use.
- This process also allows the use of product which has already crystallized.
- Wannate® HMDI is sensitive to moisture and must be stored in tightly sealed container.
- It can be stored for at least 12 months at tempertures between 0 and 30°C.
