* Decomposition
Solubility: soluble in esters, ketones, aromatic hydrocarbons. In most cases, using the ester / aromatic hydrocarbon mixtures.
Application:
* Preparation of aliphatic poly-isocyanate derivatives, such as: pre-polymer, polymer and processing the three compounds.
* Non-yellowing polyurethane resin products
* IPDI is also designed for water-based dispersion of polyurethane polymers, these polymers can be widely used in textiles,
Leather and many plastics.
* They are used in the preparation of polyurethane coatings excellent weather resistance, these coatings for the automotive original paint, paint and repair
Other means of transport and powder decorative paint.
