ISO-CURE® MDI Isocyanates
Aromatic isocyanates based on methylenediphenyl diisocyanate
ISO-CURE® MDI isocyanates are aromatic isocyanates based on methylene diphenyl diisocyanate (MDI). The available grades are suitable for the formulation of 1K and 2K PU systems, particularly as hardeners in industrial coatings, production of adhesives, cast resin systems, rigid foams, and other CASE applications. The MDI-based systems are characterised by high reactivity, while the moulded articles exhibit excellent mechanical properties. They are preferred when high strength, good chemical resistance, and toughness are required. These isocyanates are RoHS compliant according to EU Directives 2011/65/EU (“RoHS”) and 2015/863/EU (“RoHS III”).
Area of application
For the formulation of 1K and 2K PUR systems.

Storage and transport
Store in a dry and airtight, closed container at 10 – 35°C. Can be stored for at least 12 months in original sealed containers under the above conditions. Short-term deviations during transport and storage are acceptable.
Processing
The EC safety data sheet provides information on safety-relevant product properties.
All products contain diisocyanates (content > 0.1%): As of August 24, 2023, appropriate training must be provided before industrial or commercial use.
