SYNTHALAT A 149 HS

SYNTHALAT-A 149 HS is a hydroxyl group-containing, high-solid polyester-containing acrylic resin supplied as a 77% solution in butyl acetate. It is primarily used in combination with polyisocyanates for air- and oven-drying two-pack high-solid clear- and pigmented topcoats for metals and plastics. Here are its key characteristics, properties, and applications:

Characteristics:

• Supplied as: 77% in butyl acetate
• Application: Two-pack high-solid clear- and pigmented topcoats for metals and plastics
• Provides coatings with high mechanical properties, quick physical drying, high gloss and body, and excellent weather and chemical resistance
• VOC content: < 420 at spray viscosity

Properties:

• Hydroxyl value: 140-160
• Hydroxyl content: Approximately 4.5% (relative to non-volatile components)
• Viscosity: 5,000 – 10,000 mPas (as supplied)
• Hazen colour value: < 50 (as supplied)
• Non-volatile content: 77 +/- 1%
• Flash point: 30 - 34°C
• Density: 1.06 – 1.08 g/ml

Mixing Ratio with Polyisocyanate:

• Assuming equivalent reaction of the reactive groups (NCO:OH = 1:1), the recommended mixing ratio is calculated based on the hydroxyl content of SYNTHALAT-A 149 HS relative to solid resin

Solubility/Dilutability:

• Dilutable with various solvents including ethyl acetate, butyl acetate, butoxyl, ethoxy propyl acetate, MEK, MIBK, shellsol A, solvesso 150, toluene, and xylene
• Ensure the use of hydroxyl group-free solvents for dilution

SYNTHALAT-A 149 HS offers a versatile solution for high-performance coating applications requiring durability, quick drying, and excellent finish properties.
