Sikagard®-6220
Sprayable, high penetrating cavity wax
Sikagard®-6220 is an amber colored, durable wax with very good rust-proofing properties. It is suitable for an effective protection against corrosion in vehicle body cavities and convinces with its outstanding application properties and very good final performance. Thanks to its very high creep capability, it well protects even hardly accessible areas and tight sheet intervals.
After drying, a brown, slightly sticky wax coating remains that protects cavity areas from corrosion.
- Very good creep capability making easy application even at colder temperatures
- Excellent film building properties
- Outstanding water displacing
- Good low temperature behavior
- Heat resistant
- No hazing during application
- Permanently elastic
- Lower solvent content
- High road salt resistance

Application
Surface Preparation
Surfaces must be clean, dry and free of rust, dust and grease. Bare metal must be pre-treated to enhance corrosion resistance (e.g. uncoated steel, etc).
Application
Sikagard®-6220 can be applied by light airless spray equipment or by air-mix guns with an air pressure of approx. 3 - 6 bar. Use either the Sika® CW Gun (pressure cup type) or the Sika® UBC+ Gun (vacuum type) to apply the product.
Shake can approx. 40 times before use. Cover adjacent surfaces prior the spray process. Spray at room temperature and from a distance of approx. 25 cm on the surface or in the cavity using a flexible hose. Use the existing or drill access points in the car body. Spray a continuous coat and do not spray on parts of the brake, engine or exhaust system.
Removal
Uncured Sikagard®-6220 can be removed from tools and equipment with Sika® Remover-208 or another suitable solvent. Once dried, the material can only be removed mechanically. Hands and exposed skin shall be washed immediately using hand wipes such as Sika® Cleaner-350H or a suitable industrial hand cleaner and water.
Do not use solvents on skin.
Overpainting
Sikagard®-6220 cannot be overpainted.
