Polyisocyanates containing uretidione and allophanate groups, a process for their production, and their use in one and two component coating compositions |
摘要 |
Disclosed herein is a liquid, monoallophanate-containing, monouretidione-containing polyisocyanate composition characterized by having (i) an isocyanate functionality of between 2.8 and 6.5, (ii) a free NCO content of 10% to 47% by weight, (iii) a viscosity of less than 1000 cp (25 DEG C.), and (iv) the presence of monouretidione and monoallophanate groups in a molar ratio of said monouretidione groups to said monoallophanate groups of between about 20:1 and about 1:5. Also disclosed is a process for producing the above compositions, as well as their use, optionally in blocked form in one or two component coating compositions.
