Truck operators and government bodies are demanding ever lolwer standards of interior and exterior vehicle noise. Sika has formulated two high technology solutions to facilitate significant reductions in vehicle noise by absorption of vibration within the vehicle body. SikaBaffle is a pre-shaped moulded thermoplastic or extruded rubber based product used to significantly improve acoustic performance. SikaBaffle is inserted in the vehicle structure during body shop assembly and expands during exposure to the E-Coat/KTL oven. SikaDamp spray-on technology is a unique, spray applied damping solution designed to minimize interior noise through a flexible one layer application. The spray-on material adheres to the E-coat/KTL coating to ensure maximum corrosion protection. The applied spray-on damper is heat cured and can be used prior to application of under body coating or exposure to paint bake ovens. Sikaflex one-component polyurethane and hybrid sealants are typically applied in the trim shop environment and provide an excellent barrier to moisture and external noise ingress from outside the cabin.
