    Solubility / thinnability   Setalux D A 450 BA/X can be thinned to a solids

                                content of 20 % using esters, ketones and ether

                                esters. However, the solutions formed must be

                                tested for their storage stability. Toluene and

                                xylene are suitable as diluents.Only PU grade

                                solvents should be used (< 0.05 % water).

                                They should contain no other reactive impurities


    Compatibility              Generally speaking, Setalux D A 450 BA/X is

                               miscible with the Desmodur®grades listed. However,

                               the combinations must be tested for their

                               compatibility. Setalux D A 450 BA/X can be mixed

                               with Desmodur® HL*, IL, L, N 75, N 3390and Z 4470

                               It is also compatible with certain nitrocellulose

                               chips, various vinyl copolymers and other Setalux

                               D A grades. Setalux D A 450 BA/X has only limited

                               compatibility with Setal grades.
                               *With increasing age of the polyisocyanate,

                               incompatibility may develop between

                               Setalux D A 450 BA/X and Desmodur HL.


    Properties / Applications  Setalux D A 450 BA/X is suitable for combination

                               with Desmodur® N 75 or to formulate fast-drying

                               two-component polyurethane coatings, e.g. for the
                               industrial furniture finishing. It can also be

                               combined with other Setalux D A grades to

                               formulate primer surfacers and fast-drying

                               automotive and industrial coatings.
                               With Desmodur HL as the co-reactant,

                               Setalux D A 450 BA/X yields extremely
                               fast-drying coatings which are soon dry enough

                               to sand and stack.


    Storage                   When stored in sealed containers at temperatures

                              not exceeding 30 °C, the product will remain stable

                              for 12 months.
