General Type
These polyisocyanates modified with multifuncitonal alcohols are used as crosslinkers for reactive coatings. In combination with our NIPPOLAN® or other polyols (polyester, epoxy, or acrylic resins), they can be applied in a wide range of coating fields, such as wooden products, metals, plastics, rubbers, concrete, paper, and leather.

Moisture Curing Type
These prepolymers react with atmospheric moisture to produce higher molecular weight polyureas and thereby form cured films on the substrates. They are used as primer materials for wooden and plastic products and as cross-linking agents applied in combination with polyols.
