Features and Benefits

  • Low Outgassing: Exhibits low gassing properties in high vacuum environments.
  • Chemically Resistant: Cures to a hard surface that is resistant to most acids, alkaline detergents, lubricants and chemicals.
  • Color Retention: Provides excellent colorfast, non-chalking finish.

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 Apply coating by spray methods, or by brush to small areas. Aeroglaze® A276 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.
  • Spraying
    Apply coating using HVLP spray equipment. Dilute coating with 10-25% Aeroglaze® 9958 thinner, by volume. 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.
  • Brushing
    If necessary, use a brush to touch-up small areas. Add up to 5% of Aeroglaze® 9958 thinner to facilitate application properties.
    Depending on surface characteristics, the optimum dry film thickness of Aeroglaze® A276 coating should be 38.1-50.8 micron (1.5-2.0 mil). Wet film thicknesses above 127 micron (5 mil) can cause bubbling and sagging. Coverage rate is 7.4-9.8 m2/L (300-400 ft2/gal).


N/A Aeroglaze® A276 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 14 days. Lower temperatures and humidities will retard cure, while higher temperatures and humidities may cause bubbling.
Aeroglaze® A276 coating may be recoated after the first application within 4 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.

Precautions for Use and Storage

Precautions for Use and Storage
