This invention relates to flexible cycloaliphatic diisocyanate trimers and a process for the preparation of these. These flexible products are allophanate-modified, partially trimerized cycloaliphatic diisocyanates and are characterized by a low T9. More specifically, the T9 of the resultant product ranges from about -30 0C to about 40 0C, after the excess monomer has been removed from the product.
