Sikagard®-6470
Sprayable fast curing stone chip protection coating
Sikagard®-6470 is a durable, thixotropic, rubber-based protective coating with very good rust-proofing and sound deadening properties. Sikagard®-6470 is suitable for an effective protection against stone chip impacts to the vehicle body and convinces with an outstanding final performance. Thanks to its advanced application properties, original textures can easily be reproduced.
Sikagard®-6470 shows best in class over paintability performance especially with water based paint systems. A tough coating remains after drying, protecting metal from impact and corrosion.
- Easy application with no running or dripping

- Easy reproduction of original textures
- Great acoustic and damping properties
- Excellent adhesion performance to a wide variety of substrates
- Remains flexible when dry
- Outstanding low temperature behavior
- Good heat resistance
- Fast drying
- Quickly over paintable

Areas of Application
Sikagard®-6470 is a spray applied anti-corrosion coating for repair and protection of vulnerable, painted parts of vehicles such as door sills, wheel arches, front and rear aprons. It can also be applied as a sound-deadening product for example on wheel arches etc.Sikagard®-6470 shows very good adhesion on different paints, metal primers, metals and PVC without any pre-treatment.
This product is suitable for experienced professional users only. Test with actual substrates and conditions have to be performed to ensure adhesion and material compatibility.

The above information is offered for general guidance only. Advice on specific applications will be given on request.
Application
Surface preparation
Surfaces must be clean, dry and free of rust, dust and grease. Bare metal must be pretreated to enhance corrosion resistance (e.g. uncoated steel, etc).
Application
Sikagard®-6470 can be applied by air-mix guns with an air pressure of 3 - 6 bar. Use either the Sika® SCP 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 in an grid motion to build up a continuous coat.
Sikagard®-6470 can be applied haze free and does not drip. Apply this product until the desired layer thickness is reached. If a thick layer is required, let layers dry in between. A wide variety of textures can be produced by altering the spray technique. Do not spray on parts of the brake, engine or exhaust system.
Removal
Uncured Sikagard®-6470 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®-6470 is over paintable after approximately 60 minutes with most commonly used conventional paint systems (incl. water based paint systems). Waiting time can be reduced by accelerated drying at max. 60°C. Due to the wide range of paints adhesion and compatibility tests are necessary.
