SETALUX® D A 170 BA

SETALUX® D A 170 BA is a polyisocyanate cross-linking acrylic resin primarily used in combination with aliphatic polyisocyanates to formulate two-component polyurethane coatings. Here's a summary of its features, applications, and specifications:

Type:

• Polyisocyanate cross-linking acrylic resin
• Hydroxyl content: approximately 2.6% on solid resin

Uses:

• Formulation of two-component polyurethane coatings with good light-fastness and resistance to chalking

Form Supplied:

• Approximately 70% in butyl acetate

Specification:

• Non-volatile content: 70 ± 1%
• Viscosity at 23°C: 3750 ± 1000 mPa·s
• Acid value (supply form): 13 ± 2 mg KOH/g
• Hydroxyl content (supply form): 1.6 to 2.0%
• Hazen colour value: ≤ 50
• Water content: ≤ 0.1%

Other Data:

• Equivalent weight (supply form): approximately 945 g/eq
• Density at 20°C: approximately 1.02 g/cm³
• Flash point: approximately 25°C

Properties / Applications:

• Used in air- and force-drying topcoats and anti-corrosion coatings for steel in civil and hydraulic engineering applications
• Suitable for brushing, rolling, and airless spraying
• Offers good weather stability, resistance to water, washing solutions, and chemicals
• Stable up to approximately 150°C, but yellowing may occur at higher temperatures
• Can be used in anti-corrosion primers and primer surfacers for automotive refinish and transportation coating applications

Solubility / Thinnability:

• Can be thinned to a resin content of 30% using ketones, esters, ether esters, toluene, xylene, and solvent naphtha 100
• Solutions formed must be tested for their storage stability, and only PU grade solvents should be used

Compatibility:

• Compatible with various aliphatic polyisocyanates, including Desmodur N 75, N 3390, Z 4470 and L, and with SETALUX D A 450
• Also compatible with certain types of nitrocellulose chips and vinyl copolymers, but compatibility testing is advisable

Storage:

Stable for at least 730 days when stored in originally sealed containers at temperatures not exceeding 30°C

Labeling and REACH Applications:

• This product data sheet should be used in conjunction with the corresponding Safety Data Sheet for safety-relevant information
• Safety Data Sheets will be revised and distributed to reflect any updates in safety-relevant information

Overall, SETALUX® D A 170 BA offers versatility in formulating polyurethane coatings with excellent performance properties, making it suitable for various industrial and automotive applications. However, proper handling, storage, and compatibility testing are essential to ensure optimal results and safety.
