AEROGLAZE® A276

• 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 fi nish.

Surface Preparation

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 LORD representative for recommended Aeroglaze primer required for your application.

Applying

• Apply coating by spray methods, or by brush to small areas. Aeroglaze A276 coating is best applied at 13-35°C (55-95°F), with substrate temperatures at least 2.8°C (5°F) above the dew point.
• Spraying:Apply coating using siphon or pressure pot spray equipment. Dilute coating with 10-25% Aeroglaze 9958 thinner, by volume.
• 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, optimum dry fi lm thickness of Aeroglaze A276 coating should be 38.1- 50.8 micron (1.5-2.0 mil). Wet fi lm thicknesses above 127 micron (5 mil) can cause bubbling and sagging. Coverage rate is 7.4-9.8 m2/L (300-400 ft2/gal).

Curing

• 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 (see Temperature/ Relative Humidity Graph), 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 fi rst 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 adhe sion failure.
• If the maximum recoat time is exceeded, the surface must be roughened by sanding with fi ne sandpaper before recoating.

Cleanup

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

Limitations

• Not for immersion service. Do not apply to wet or damp substrates.
• Aeroglaze A276 coating contains aliphatic isocyanate monomer. Spray only in properly ventilated areas with specifi ed respiratory protection.

15 day cure at room temperature, 24 hours at 50°C (122°F).
