Aeroglaze® Z307 coating is an absorptive polyurethane coating designed for application on substrates used in aerospace operations. These operations include those where coatings must exhibit low outgassing characteristics while providing high thermal absorptivity properties. Aeroglaze® Z307 coating cures to a flat black finish.

Features and Benefits

  • Low Outgassing: exhibits low gassing properties in high vacuum environments.
  • Durable: provides mechanical properties required for rigorous durations in space; provides excellent performance on rigid or flexible substrates.
  • High Thermal Absorptivity: provides thermal absorptivity for applications where superior heat absorption is required.
  • Static Dissipation: provides static dissipating properties.

Directions for Use

Surface Preparation

N/A Thoroughly clean surfaces to remove all dust, oil and grease. For most substrates, apply primer to ensure proper adhesion and performance of the coating. Contact your SOCOMORE representative for recommended Aeroglaze® primer required for your application.


N/A Before opening container, thoroughly mix coating using a paint shaker for 5 minutes. Open the lid carefully as the container may be under slight pressure. Stir coating with a clean paint stick to check for any settled material and ensure mixture is homogeneous. If material has settled, return closed container to the paint shaker and shake an additional 5 minutes or until no settling is apparent.
Dilute coating with 15-20% Aeroglaze® 9958 thinner, by volume, to a Zahn Cup #2 viscosity of 18-22 seconds.


N/A Apply coating by HVLP or airless spray equipment. Aeroglaze® Z307 coating is best applied at 13-35 ºC (55-95 ºF), with substrate temperatures at least 2.8 ºC (5 ºF) above the dew point.
Apply Aeroglaze® Z307 coating at a maximum thickness of 19.05 dry micron or 101.6 wet micron (0.75 dry mil or 4 wet mil) per coat. Typical dry film thickness of Aeroglaze® Z307 coating should be approximately 38.1-50.8 micron (1.5-2.0 mil).
Hold the gun at right angles to the surface, approximately 20.3-30.5 cm (8-12 in) away, and apply with a 50% overlap. A light mist coat should be applied, followed by a full wet coat of 76.2-101.6 wet micron (3-4 wet mil). Coverage rate is 7 m2/L (284 ft2/gal).


N/A Aeroglaze® Z307 coating cures by reacting with moisture in the air. Cure rate is dependent on the temperature, relative humidity and amount of air circulation needed to remove the solvent.
Under the acceptable curing conditions, the coating will develop its ultimate properties in approximately 7 days. Lower temperatures and humidities will retard cure, while higher temperatures and humidities may cause bubbling.
Aeroglaze® Z307 coating cures to a tack-free surface in 2-3 hours at 25 ºC (77 ºF) and 50% relative humidity. Room temperature cure times of 12 hours permit handling; 36-48 hours permit normal usage.
Aeroglaze® Z307 coating may be recoated after the first application within 3 hours minimum and 24 hours maximum. Recoat time is dependent on temperature and humidity. High temperature and humidity promote fast cure while low temperature and humidity slow down the cure. In high temperature and high humidity conditions, recoat within 8 hours to prevent intercoat adhesion failure.
If the maximum recoat time is exceeded, the surface must be roughened by sanding with fine sandpaper before recoating.


N/A Use Aeroglaze® 9958 thinner to clean equipment. Do not use lacquer thinners, water or solvents containing alcohols.
