Evonik Vestanat IPDI Isophorone Diisocyanate 4098-71-9
Manufacturer ： EVONIK Degussa
Structure :3-isocyanatomethyl-3,5,5-trimethylcyclohexyl isocyanate
Physical property parameters
Viscosity (23</strongplastic technology (RIM) and water-based adhesives or hot melt glue. In polyurethane resin technology, the preparation of water-based polyurethane dispersions is the most important application of VESTANAT®IPDI, because this starting material can be used to produce low-viscosity prepolymers and final products with low co-solvent content . It is the hard segment component of the resin. If excellent yellowing resistance and low reaction dilution are required Depending on the agent or co-solvent content, you can choose polyurethane acrylates (conventional or water-based) for radiation curing based on VESTANAT IPDI synthesis.
Application in the field of two-component polyurethane, VESTANAT®IPDI is an addition product with trihydric alcohol (such as: with TMP adduct) or in the form of polyisocyanate (such as: VESTANAT®T1890). This use is primarily for large vehicle and automotive coatings (OEM and refinish).
VESTANAT®IPDI and its polyisocyanates can be used to prepare blocked polyisocyanates. These blocked polyisocyanates can be used for electrostatic spraying powders Cross-linking agent for coatings and solvent-based industrial paints, especially can coatings and coil coatings. IPDI-based cross-linking agent gives solvent-free two-component polyurethane excellent light stability and mechanical properties. This type of system is mainly used in elastomeric coatings and casting resins. Hard systems can be used as industrial materials.
Activity and Catalysis
Storage and transportation
It is supplied in � and 200kg drums, and can also be supplied in tank trucks and storage tanks. If moisture can be eliminated, IPDI can be stored for at least one year without affecting the quality of the above standards. Long-term storage will increase the color index.
