SYNTHALAT A 147 HS

SYNTHALAT-A 147 HS is a hydroxyl group-containing polyester/acrylic-resin supplied as a 70% solution in butyl acetate/butyl glycol acetate (25:5). 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: 70% in butyl acetate/butyl glycol acetate (25:5)
• Application: Two-pack high-solid clear- and pigmented topcoats for metals and plastics
• Provides coatings with high mechanical properties, high gloss and body, and good weather and chemical resistance

Properties:

• Hydroxyl value: 140-160
• Hydroxyl content: Approximately 4.5% (relative to non-volatile components)
• Viscosity: 1,500-2,500 mPas (as supplied)
• Gardner colour value: < 2 (as supplied)
• Non-volatile content: 70 +/- 1%
• Flash point: Approximately 28°C
• Density: Approximately 1.04 g/ml
• Acid value: 20-30 (relative to non-volatile components)

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 147 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

Compatibility:

• Compatible with various compounds including Synthalat A-045, A-055, A-060, A-065, A-075, A-077, A-084, A-085, A-088 MS, A-120, A-125 HS, A-135, A-135 N, A-141 HS, A-150, A-150 S, A-151, A-156 HS, A-190, A-191, A-192, A-200, A-1613, A-1615, A-1633, A-1653, Synthoester-HD 080, HD 165, HD 170 HS, TS 8013, TS 186 HS, Synthalan-LS 768, HS 86 B, Cellulose acetobutyrat, and others
• Compatibility with various polyisocyanates including Desmodur N 75, IL, N 3390, HL, L 75, L 67, Vestanat T 1890 L, Tolonate HDT-LV

These properties make SYNTHALAT-A 147 HS suitable for a wide range of coating applications requiring durability and high performance.
