- Advantages
SUSPENO 201-NBA is a soft creamy paste, which allows for weighing and batch process or mill base.
- Reduce Dispersion Time
- No Breakup of Paste or Powder
- No Waste
- Lower Activating Temperature
The Added Feature: MOISTURE FREE
SUSPENO 201-NBA is Moisture Free, making it eminently suitable for wood finishes (clear and pigmented sealers) where clarity and absence of iron color are essential. Zero moisture is important for urethanes and epoxies, and critical for coatings containing zinc, including aerosols.
Applications & Uses
- Applications
- Applications
SUSPENO 201-NBA is recommended for nonaqueous industrial coatings and related products. It is particularly well suited to high solids, low V.O.C. systems:
- Automotive Finishes
- Pigmented Lacquers
- Maintenance Coatings
- Aerospace Coatings
- Use Level
Many factors govern the amount to be used: The recommended range is 0.8% to 2.0%. A conservative starting point for evaluation is 1.25% based on total formulation, which allows the operator to reduce or increase the dosage according to the performance requirements of the formulation. A ladder series can be run to obtain optimum lading.
- Formula Replacement
SUSPENO 201-NBA can convert current anti-settling paste and pourable technology formulas to a H.A.P.’s compliant system based on solids of product being replaced. Incorporation and production procedures will remain the same.
- Manufacturing Procedure
To maximize effectiveness SUSPENO 201-NBA should be incorporated with the pigment portion and sufficient vehicle plus solvent to provide a workable mill base. Good shearing action and dwell time (10-15 minutes minimum) are required. To standardize against variable ambient temperature, a minimum dispersion temperature is 100°F (37°C) or 120°F (48°C) is substantial aliphatic solvent is present. Although there is no upper temperature limit, the flash points of the solvent (n-butyl acetate) should be recognized. Cowles mixers along with high shear media, pebble and roller mills are recommended to achieve rapid dispersion. SUSPENO 201-NBA’s soft creamy feature will allow for rapid pre-mixing compared to old paste anti-settling agents.
Note: SUSPENO 201-NBA is not recommended for post-milling stir in use.
- Use with Other Rheological Agents
SUSPENO 201-NBA is synergistic with most organic thixotropes, for example the POLYTROLS, SUSPENO 70 and the organo-clay gellants. Such use depend on the desired properties with due consideration of the viscosity factors.

Technical Details & Test Data
- True Viscosity : Significance
The Stormer and effluent type viscometers record apparent viscosity in the mid range. Such information is useful for production quality control. But it does not deal with what actually takes place under the conditions relating to sagging and pigment suspension.True viscosity is a critical factor for any coating that requires pigment suspension, anti-settling and sag control. The term means real viscosity in contrast with the apparent viscosity, which is simply a reading by the Stormer viscosimeter in the medium shear range.Gellants and organic thickeners perform satisfactorily in terms of sag control and pigment suspension but they add viscosity which is undesirable particularly in high solids, low V.O.C. systems or conventional products finishes and industrial coatings.
Note: Both High Solids Systems and Industrial Coatings require high viscosity in the ultra low shear range.
