Sika Corp., a supplier of adhesive and sealant solutions, recently introduced the Sikagard-6682 sound-deadening and anti-chip underbody coating.
Sikagard-6682 is developed for the transportation market to improve vehicle acoustic performance, reducing road noise and structure-borne vibration noise.
“Sikagard-6682 provides significant performance in sound reduction on trains, buses, RVs, engine supports and vehicle parts,” said Mark Daniels, VP of industry transportation and appliance and manufacturing. “Our customers have seen up to a 30 percent reduction in noise.”
In addition to providing noise reduction, Sikagard-6682 is an anti-stone and chip coating to vulnerable parts of the vehicle, helping to enhance corrosion performance of pre-applied coatings, the company stated. It exhibits adhesion to commonly-used coatings and primers used in the transportation industry, including those on metallic and wood substrates. It also is over-paintable.
Sikagard-6682 is a water-based acrylic that can be applied with standard spray equipment without drips or mess. It can be applied up to 5-millimeter thick in one application with no sag.
