Liqui Moly Underseal Black (Spray)

Liqui Moly Underseal Black (Spray) is a stoneguard coating, based on rubber and resins. This underseal is distinguished by fast drying and the ability to be painted over, provides abrasion-resistant corrosion protection, offers excellent protection against stone chipping and has sound-absorbing properties. After drying completely, a permanently elastic film remains. This underseal can be painted over using commercially available paint systems and is easy to grind after drying.

Suitable for the coating of bare and painted surfaces, predominantly for vehicle underbodies and repairing or supplementing existing PVC or rubber/resin-based coatings. Is mainly used for after treatment or repair work on areas of vehicle underbodies which are difficult to access (such as angles, corners, edges etc.) in which rust tends to form.

Application

Clean the surfaces to be treated thoroughly in advance and remove rust. The surfaces must be dry and free of wax, dirt and grease and largely free of dust. Shake well before use! When the ball has worked loose, continue to shake the can for another minute. Hold the can vertically when spraying and apply the contents thinly from a distance of about 20 to 30 cm. The resistance to abrasion and corrosion increases with increasing coating thickness. For this reason, the spraying process should be repeated once or twice after a short flash-off period. Should be sprayed using a cross pattern to avoid spray shadowing. Can be painted over after approx. 60 to 90 min. (depending on film thickness, temperature and humidity). Most of the usual water and solvent-based 2C paints and base coats can be used here. When using a 2C paint, we recommend using a coat of plastic primer first and painting over this coat after it is completely dry, as recommended by most paint manufacturers.

Recommended application temperature: 15 -25 °C. We recommend applying thin coats. Depending on the desired layer thickness, intermediate drying should be carried out after each layer. If the stoneguard is subsequently painted over, the coats will become increasingly hard. In other words, the treated surface should be treated accordingly with adhesive primer for plastics in the same way a plastic surface would be. 

After use, the can should be inverted and sprayed until the valve is clear and only propellant escapes. Do not spray material onto moving parts and hot components such as mechanical joints, the engine, gearbox, drive shaft, exhaust pipe, catalyst and brake systems.

Benefits:

• Very good resistance to weathering, salt spray and abraded material
• Good adhesion of water-based paints on these coatings
• Very good adhesion on various substrates
• Good stoneguard properties
