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.
