Product FAQ
Q:
VESTANAT®TMDI, here we only introduce the synthesis application of UV resin, can it be used for the synthesis of other resins?
Yes, VESTANAT®TMDI-based urethane modified resins can be used in coating production, and its derivative products have high flexibility, excellent compatibility and low viscosity, and applications include thermal curing systems, polyurethane dispersions and radiation curing polyurethane acrylic systems. Even if VESTANAT®TMDI is used to partially replace diisocyanates, the properties mentioned above will change significantly.
Q:
Are there similar products in the Chinese market? What are the differences?
No, currently only Evonik in Germany produces TMDI series products.
