Henkel’s weight-saving Teroson RB 8275 LASD

One new trend that is growing across the automotive industry is of sound-deadening materials that can be sprayed onto car bodies by robots. They are increasingly replacing bitumen mats.

Henkel is now introducing the fourth generation of its rubber-based acoustic materials to the market. Its Teroson RB 8275 is already being used at leading car manufacturers. The new product, a liquid applied sound deadener (LASD), is claimed to significantly reduce the solid-borne noise generated by the engine and the wheels during driving.

“The new Teroson RB 8275 exhibits a whole series of advantages over its own predecessors and other competing sound deadening materials,”

says Manfred Kosche, Henkel Product Line Manager for LASD products. Its acoustic performance is more than 15 percent higher than the current industry standard.

20 percent lighter

In addition to this, Teroson RB 8275 saves up to 20 percent weight compared with today’s standard products. Simply by switching to the Henkel innovation, car makers can reduce the weight of a vehicle by about 1 kilogram. “That may not seem much to a non-specialist, but it represents a huge step forward for a vehicle designer habitually endeavoring to save a gram here or there,” explains Kosche. Less weight means less consumption, and it provides opportunities to incorporate more safety components or comfort-improving features in the car.

The environment benefits The environment doesn’t just benefit from the reduced fuel consumption throughout the car’s usually years-long service life. Teroson RB 8275 is based to a large extent on renewable raw materials, which reduces the dependency on traditional raw materials such as crude oil or its derivatives.

Henkel says Teroson RB 8275 is, in effect, a really neat solution for customers. They no longer have to live with the time-consuming, manual fitting of up to 30 conventional bitumen mats in each car body which generates a great deal of dust and dirt. The automated spraying of liquid applied Teroson is a clean process.

Nearly all the bitumen mats used today can be replaced by Teroson RB 8275. This also helps to assure consistent quality, since spray application by robot is faster and more precise than manual bonding of mats. The new Teroson does not require any hazard labeling and the low level of emissions also lies significantly below today’s thresholds.

Henkel began producing rubber-based LASD products for the automotive industry in Europe in 2006. Today Henkel supplies innovative sound deadening materials to leading auto brands around the world.
