Chameleon Copper Weld Through Primer Undercoat Aerosol

Chameleon Copperweld Weld Through Primer Aerosol is a specialized primer designed for automotive and industrial applications where welding is required. Its key feature is its ability to allow welding directly over the primed surface without compromising weld quality or corrosion protection.

Here are some details about its typical properties and application:

Key Features and Benefits:

 * Weld-Through Capability: The primary advantage is that it enables spot, MIG, and TIG welding directly onto the primed metal, minimizing the need for primer removal.

 * Excellent Conductivity: Enriched with copper (and sometimes zinc), it provides high electrical conductivity, crucial for efficient welding.

 * Corrosion Protection: Offers superior rust protection to bare metal surfaces.

 * Fast Drying: Speeds up the repair process, with tack-free times typically around 10-20 minutes and re-sprayable in about 60 minutes.

 * **Minimizes Heat Zone, Distortion, and Splatter: Helps to reduce the heat-affected zone, minimizing panel distortion and weld splatter.

 * Good Sprayability and Coverage: Designed for easy application with good atomization and coverage.

 * Heat Resistant: Can withstand temperatures up to approximately 110°C.

Typical Properties:

 * Color: Metallic copper (often described as gold).

 * Container Size: Commonly available in 450ml or 500ml aerosol cans.

 * Density: Around 886 g/l (this can vary slightly between manufacturers).

 * VOC (Volatile Organic Compounds): Regulatory VOC typically around 544 g/l, Actual VOC around 320 g/l. (Always check local VOC regulations for compliance).

Application Instructions:

 * Surface Preparation: The surface must be clean, dry, and free of grease, oil, and rust. It's often recommended to sand the bare metal with 80-grit paper.

 * Shake Aerosol: Shake the can vigorously for at least one minute after the mixing ball begins to rattle to ensure uniform color and prevent clogging.

 * Temperature: For best results, use when the can temperature is around 21°C (70°F).

 * Application: Apply 2 medium wet coats to both surfaces that will be welded.

 * Flash Time: Allow 3-5 minutes flash time between coats.

 * Drying Before Welding: The coating must be completely dry before welding, which typically takes around 20 minutes.

 * Post-Welding: Remove any excess primer before applying any filler, as it may cause lifting.

 * Clean Nozzle: After each use, invert the can and spray for a few seconds to clear the spray tip and prevent clogging.

Safety Precautions:

 * Extremely Flammable: This product is an extremely flammable aerosol. Keep away from heat, sparks, open flames, and hot surfaces. Do not spray on an open flame or other ignition sources.

 * Pressurized Container: Do not pierce or burn, even after use. Protect from sunlight and do not expose to temperatures exceeding 50°C (122°F).

 * Ventilation: Use only outdoors or in a well-ventilated area.

 * Personal Protective Equipment (PPE): Wear appropriate eye protection, protective clothing, and protective gloves to avoid skin and eye contact.

 * Inhalation: Avoid breathing vapors, fume, or spray. May cause drowsiness or dizziness. If inhaled, remove to fresh air.

 * Skin/Eye Contact: Wash thoroughly after handling. If on skin, wash with plenty of water. If in eyes, rinse cautiously with water for several minutes and seek medical advice immediately if serious damage occurs.

 * Storage: Store in a cool, dry, well-ventilated place, away from heat, sparks, and flames, and store locked up.
