SETALUX® 1279 BA-70

SETALUX® 1279 BA-70 is an acrylic polyol with 3% OH (hydroxyl group content calculated on non-volatiles). Let's break down its technical datasheet:

Technical Features:

• Hardness: Good
• Flexibility: Tough but flexible
• Build and Gloss: High
• Chemical Resistance: Excellent
• Chalk Resistance: Good
• Light Fastness: Good
• Gloss Retention: Good

Solvent Composition: Butyl acetate

Specifications:

• Non-volatile content: 69.0 - 71.0%
• Acid value (as such): 5.5 - 8.5 mg KOH/g
• Viscosity (at 23°C, 100 s^-1): 1.5 - 3.5 Pa.s
• OH content (as supplied): 2.0 - 2.4%
• Colour APHA (Lico): Maximum 50 APHA
• Appearance: Clear, free of extraneous matter

Typical Properties:

• Density: Approximately 1.03 kg/dm³
• Flash point: Approximately 21.5°C

Application: It is suitable for automotive coatings and industrial coatings.

Dilutability: It can be thinned to a solid content of 30% with ketones, esters, ether esters, toluene, xylene, and solvent naphtha 100. The storage stability of the respective solutions must be tested. Only PU grade solvent (< 0.05% water, free of other reactive impurities) should be used.

Compatibility: SETALUX 1279 BA-70 can be mixed with various isocyanates and SETALUX D A types, but individual cases must be tested for suitability. It is generally miscible with most CAB (cellulose acetate butyrate) grades, but the compatibility of combinations must always be tested.

Storage: It is typically stored in 200kg steel drums. Storage should be under cover, out of direct sunlight, and avoiding extreme temperature changes. Sealed, unopened containers have a shelf life of 12 months from the date of manufacture under normal storage conditions (5 - 35°C). If stored for longer than 12 months, it is recommended to recheck the product for suitability in the intended application.
