Sikagard®-6682 sound-deadening and anti-chip coating is developed for the transportation market to improve vehicle acoustic performance, reducing road noise and structure-borne vibration noise, to provide a quieter ride for both drivers and vehicle occupants.

"Sikagard-6682 provides significant performance in sound reduction on trains, buses, recreational vehicles, engine supports and vehicle parts," said Mark Daniels, Vice President, Industry Transportation and Appliance and Manufacturing for Sika Corp. "Our customers have seen up to a 30% reduction in noise."

In addition to providing noise reduction, Sikagard-6682 is a durable anti-stone and anti-chip coating to vulnerable parts of the vehicle, helping to enhance corrosion performance of pre-applied coatings. It exhibits excellent adhesion to commonly used coatings and primers used in the transportation industry, including those on metallic and wood substrates. It has good resistance to abrasion and is over-paintable, making it a versatile option for many different areas on a vehicle.

Sikagard-6682 was designed with the needs of modern manufacturing conditions in mind. The product is a water-based acrylic and is easily applied with standard spray equipment without drips or mess. It can be applied up to 5 mm thick in one application with no sag, making it ideal for hard-to-reach areas in underbody situations.
