SETALUX D A 450 BA 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 yields extremely fast-drying coatings which are soon dry enough to sand and stack.
As the polyol component in the formulation of fast-drying two-component polyurethane coatings.

Technical Details & Test Data
- Solubility
SETALUX D A 450 BA 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 is miscible with the Desmodur® grades listed.
However, the combinations must be tested for their compatibility. SETALUX D A 450 BA can be mixed with Desmodur HL*, IL, L, N 75, N 3390 and Z 4470. It is also compatible with certain nitrocellulose chips, various vinyl copolymers and other SETALUX D A grades.
SETALUX D A 450 BA has only limited compatibility with SETAL® grades. *With increasing age of the polyisocyanate, incompatibility may develop between SETALUX D A 450 BA and Desmodur HL.
