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.
