| SINGULARITYTM Black |
Under contract to NASA, NanoLab developed a number of coating processes for the production of very high absorbance optical blacks for stray light suppression. NanoLab offers three product lines to meet the needs of optical engineers and artists: Singularity Black LT Aero Technical Data Sheet TDS SingularityTM Black, What is it? Singularity Black LT is a nanotube filled, solvent based paint that has exceptionally strong absorption in the visible, and is similar in performance to the vertically aligned arrays of nanotubes that are the blackest items known to mankind. Singularity has world class performance in the visible, NIR and IR (<1% reflectance in the visible (400-800nm) and < 1.5% in NIR (800nm to 1400nm) exceeding the optical properties of other commercially available products like Acktar's Metal Velvet and Aeroglaze Z306. Singularity's grazing angle performance is unmatched. Formulations are available for use as beam dump coatings, black body sources, etc. Both the standard and aerospace grades offer the same optical performance. The Aerospace grade has been tested for outgassing, vibration, and other tests related to spaceflight. For the trained artist community, the Singularity lineup offers an intense matte black, a void-like experience. SingularityTM Black LT, How is it applied? The paint is solvent based, and requires application in a spray booth or fume hood, or with protective solvent vapor/particulate masks suited to the task. Air brush spraying is the recommended application technique. Substrates and spray guns should be resistant to chemical attack from solvents such as MEK and THF. An Iwata Eclipse or Badger 150 airbrush is well suited for small scale coating jobs. Coverage at ~1ml/cm2 results in a thick coating that performs well in the IR and visible. Thinner coats may perform well in the visible. After spray application, a heat cure is required to activate the coating. Once activated, it is a fragile surface with limited scratch resistance. We offer a version that can be more rigorously handled, when you use our coating services. The heat cure requires that the coating see 120C for 10 minutes. In lab, we have cured the coating with an oven, hair dryer or heat gun. While fragile, Singularity coatings can be field repaired with a air brush and a heat gun. In addition to these offerings, we have created applique' versions that let you 'wallpaper' the coating onto parts with low melting points that could not withstand our part coating process. We also offer a 'repair kit' for scratched optical components to restore black coatings to <1% reflectance in the visible. SingularityTM Black, Coating Services NanoLab provides coating services for baffles, telescope components, and other optical parts, or artists works. All work is done domestically, by US citizens in an ITAR compliant facility. For coating of customer parts, see our Or call us to discuss custom work (781) 609 2722 or email us at sales@nano-lab.com SingularityTM Black LT-AERO, What are its properties? We have collected UV-VIS-NIR diffuse & spectral reflectance values BRDF data for this coating. We have a full compliment of scratch & adhesion test data, along with vibration tests and outgassing rates for the Aerospace version. SingularityTM Black LT- AERO has been tested for various flight qualifications: ✔ Cleanliness level of <200 per Institute of Environmental Sciences and Technology (IEST) STD-CC1246E. ✔ ASTM E595-07 and ECSS-Q-70-02 Outgassing tests shows a TML of 0.4, RML 0.18, and CVCM of 0.06 ✔ Pass thermal cycling tests between -60 oC and 85 oC at a ramp rate of 10 - 20 oC/minute, per Ball Aerospace ✔ Vibration - tested to General Environmental Verification Specification (GEVS) and BPL profile

SingularityTM Black -LT
has a total hemispherical reflectance THR <1% in the visible (parts coated in our facility get a coating guarantee of sub 1% at 600nm) and <1.5% in the near infrared. On highly textured surfaces, we can make coatings that are even more absorbing across this range.
SingularityTM Black How To The video at right gives an overview of coating application technique with Singularity Black LT. We also offer classes in-house where students will work with making the deepest blacks possible using Singularity Black. You will have access in your session to our Material Scientists, Chemists, and Artist in Residence to collaborate and brainstorm with. This class is one on one and can be scheduled based on customer’s availability and lab availability. Please contact Singularity Learning Opportunities to discuss further. |
As of October 15, 2021, all Singularity Black Low Temp products will be a 2x concentrated strength, giving the customer more area coverage than previously offered with the 1x strength Over the past year, Nanolab, Inc has worked to engineer and improve their pioneer product, Singularity Black Low Temperature Optical Paint. We believe offering the 2x strength will benefit our customers while achieving the low reflectance they have come to expect with our coating but using less paint. If you want to work in the older 1x strength after October 15th, you will need to dilute this in a 50:50 ratio with THF solvent. We look forward to continuing to progress forward with our Black Optical Paints in the years to come. Any questions, please reach out sales@nano-lab.com We sell Singularity Black LT in 4 sizes: 20ml, 250ml, 500ml and 1000ml: Singularity Black Paints have a shelf life of 6 months from date of sale when unopened All Singularity Black paints are flammable, and shipped via FEDEX GROUND domestically and EXPRESS internationally, wherever hazmat shipments are allowed - please note all applicable shipping costs including all hazmat surcharges will be added to your invoice. Due to this, we do not allow returns on Singularity Black LT paint, if there is a question about use, please ask before you purchase the paint. Call (781) 609 2722 or email us at sales@nano-lab.com to get a custom quote or to have us process your parts in our state of the art, cleanroom facility. NanoLab thanks NASA for its support of the development of super-black coatings under a Phase I and Phase II Small Business Innovation Research (SBIR) grant titled “Nanostructured Super-Black Optical Materials” (S2.02-8177).
