CA1000 Mastinox Jointing Compound, 6 oz

PPG CA 1000 Mastinox is a non-curing, non-chromate corrosion-inhibitive jointing compound designed to provide a protective barrier against corrosion on aluminum alloys and between dissimilar metals.

CA 1000 is a one-part, epoxy-capped PERMAPOL® polysulfide compound formulated as a thixotropic paste. It remains permanently mastic after prolonged exposure to aircraft fuels, including jet fuel and aviation gasoline, making it well suited for aircraft assembly and maintenance applications where corrosion protection is required at metal interfaces.

CA 1000 is supplied in a 6 oz Semkit cartridge with a 4.5 oz fill and is shipped by ground only.

CA 1000 Mastinox Features & Benefits

• Non-chromate formulation: Provides corrosion-inhibitive performance without intentionally added chromium.
• Non-curing: Remains permanently mastic rather than curing to a hard or rigid material.
• Corrosion barrier: Helps protect aluminum alloys and interfaces between dissimilar metals from common causes of corrosion.
• Wide service temperature: Suitable for service from -65°F to 240°F (-54°C to 116°C), with intermittent excursions up to 275°F (135°C).
• Fuel resistant: Remains permanently mastic after prolonged exposure to jet fuel and aviation gasoline.
• One-part material: No mixing is required before application.
• Thixotropic paste: Suitable for application with a brush or spatula.
• Aerospace formulation: Designed specifically for corrosion protection applications involving aircraft materials and assemblies.

Aircraft Applications

CA 1000 is designed for applications where a corrosion-inhibitive barrier is required between metal surfaces or around aircraft components. Typical applications include:

Always verify the applicable aircraft or component maintenance documentation before using CA 1000 on an in-service aircraft.

CA 1000 Technical Properties

Values identified as typical are provided for informational purposes and should not be used as specification or acceptance criteria. Refer to the current PPG technical data sheet for complete product requirements.

Corrosion Protection Between Dissimilar Metals

One of the primary purposes of CA 1000 is to help protect aircraft structures and assemblies where dissimilar metals are in contact. Moisture and other environmental contaminants at a metal interface can contribute to galvanic corrosion. CA 1000 forms a corrosion-inhibitive barrier between applicable surfaces.

PPG testing includes galvanic-cell evaluations involving aluminum/titanium, aluminum/stainless steel and aluminum/cadmium-plated steel couples. The manufacturer's technical data reports no signs of corrosion or sealant deterioration under the specified test conditions.

Actual compatibility and corrosion performance depend on the specific materials, surface preparation, joint design and operating environment. Follow the applicable engineering and maintenance documentation for the assembly being treated.

Application

CA 1000 is supplied as a one-part material and does not require mixing. The thixotropic compound can be applied by brush or spatula.

Before application, substrates should be properly cleaned and prepared. PPG recommends removing contaminants such as dirt, grease and processing lubricants with appropriate solvents and using a clean, lint-free cloth. The prepared surface should be dried before application.

Because substrate composition and surface condition can affect adhesion, PPG recommends determining adhesion characteristics on the specific substrate when appropriate before applying the material to production parts or assemblies.

Do not apply CA 1000 based solely on this product description. Follow the applicable aircraft, component, engineering or maintenance documentation for surface preparation, application location and required thickness.

Fuel, Hydraulic Fluid & Environmental Resistance

CA 1000 is designed to maintain its permanently mastic character after prolonged exposure to aircraft fuels. Manufacturer testing also evaluates resistance to hydraulic fluid, de-icing fluid and salt-water exposure.

CA 1000 Packaging

Shipping: Ground shipping only.

Storage & Shelf Life

The current BAC listing specifies a 12-month shelf life from the date of manufacture. The available PPG technical data specifies at least 12 months when CA 1000 is stored below 80°F (27°C) in the original, unopened container.

Store the product according to the manufacturer's current technical data sheet and SDS. Do not use material beyond its stated shelf life unless otherwise authorized by the applicable manufacturer or quality procedure.

Frequently Asked Questions
