Evonik Degussa Vestanat H12MDI Hydrogenated MDI Dicyclohexylmethane Diisocyanate HMDI 5124-30-1

Product Introduction
VESTANAT H₁₂MDI is a cycloaliphatic diisocyanate. It is a low viscosity liquid with a pungent odour. For polyurethane synthesis.

Specifications

Nature and Description
cycloaliphatic diisocyanate VESTANAT H₁₂MDI, used as A material made of polyurethane with excellent light stability, weather resistance and mechanical properties. It is also particularly suitable for the manufacture of elastomers, aqueous PU dispersions and light-curing polyurethane resins. In addition to its superior mechanical properties, VESTANAT H₁₂ MDI also exhibits excellent hydrolysis and chemical resistance.

Activity and Catalysis
Aliphatic and cycloaliphatic diisocyanates are less reactive than aromatic ones. VESTANAT H₁₂ MDI usually requires an appropriate catalyst to accelerate the urethane reaction, and an organotin catalyst is recommended. (eg DBTDL or DBTDAc)
If the reaction is carried out at a relatively high temperature, there is no need to add a catalyst.

Storage and Shipping
VESTANAT H₁₂MDI is sensitive to moisture. If the influence of moisture can be excluded, it can be stored for at least 6 months without affecting the above-mentioned standard quality.

VESTANAT H₁₂MDI will partially crystallize and deposit at the bottom at a temperature lower than 25℃. In this case, it needs to be heated at 40-50℃ and homogenized before use.
VESTANAT H₁₂MDI is supplied in non-recyclable 200KG barrels.

Toxicity and Disposal
See the Material Safety Data Sheet for this product for toxicity and handling information.
