SETAQUA® B B 2624

SETAQUA® B B 2624 is a non-saponifiable polymer dispersion used as a binder for aqueous air- and force-drying coatings, particularly primers, one-coat matt finishes, and adhesion primers suitable for both ferrous and non-ferrous metals. Here's a summary of its technical details:

Type: Non-saponifiable polymer dispersion which dries by oxidation.

Form Supplied: Approximately 30% in water, neutralized with approximately 0.5% ammonia and 0.3% triethylamine, and contains no organic co-solvents.

Specification:

• Non-volatile content (1 g, 1 h, 125 °C): 28 - 32%
• Viscosity (23 °C, D = approx. 40 s-1): 1600 - 3000 mPa·s
• Acid Value: 19.5 - 25.5 mg KOH/g
• pH (10% solution with in water): 8.5 - 9.1

Other Data:

• Appearance: Turbid, brownish
• Mean particle size: < 200
• Density (20 °C): Approx. 1.0 g/cm3

Properties / Applications:

• Developed for fast-drying industrial anti-corrosion primers and one-coat finishes.
• Offers outstanding anti-corrosion properties, water resistance, and adhesion on various surfaces, but is not UV-stable and thus primarily suitable for primer formulations.
• Requires formulation with dryers and anti-skin agents.
• Exhibits good shear stability, allowing for direct pigment grinding into the binder.
• Can be applied using conventional spraying techniques, dipping, and flow coating.

Solubility / Thinnability: Compatible with water.

Compatibility: Can be combined with other aqueous binders, though compatibility should be tested.

Storage:

• Stable for at least 365 days when stored in originally sealed containers at temperatures not exceeding 30°C.
• Prone to skin formation, which can be accelerated by sun exposure and/or temperatures higher than 30°C.
• Sensitive to frost; freezing will damage the product irreversibly.
• Prolonged storage and higher temperatures may result in changes in viscosity and particle size, potentially leading to sedimentation or coagulation.
• Contamination with certain microorganisms may render the product unusable.
