Blocked aromatic polyisocyanate based on TDI. In combination with cycloaliphatic diamines such as Laromin® C 260 (BASF) to formulate highly flexible, one-component stoving coatings. Properties / Applications: Desmodur® BL 1100/1 is combined with Laromin® C 260 to formulate stoving coatings, including those for application by dipping and curtain coating, and adhesive cements. Combinations of Desmodur® BL 1100/1 and Laromin® C 260 with plasticisers can also be used as solvent-free, high-build coatings. Optimum film properties are produced by combining Desmodur® BL 1100/1 and Laromin® C 260 in the ratio 100 : 10 (by wt.). The mixing ratio was determined empirically. Information provided by Covestro |
