Highly Targeted, Highly Effective Damping

Customers' requirements are specifically geared towards eliminating or reducing low-frequency background noise, to increase acoustic comfort during driving, in fact, “comfort” remains a continuous ranking in vehicle quality ratings. At the same time, the added value for our customers is in the cost-effectiveness of the materials used and their weight-reducing effect. With their increasing emphasis on lightweight strategies, modern steel body panels are becoming thinner and thinner, or are being replaced by aluminum. These lightweight structures typically come with a loss in stiffness, which increases vibrations in the body structure and increases occupant compartment noise. Through selective application to the vibrating surface, SikaDamp® allows engineers to effectively provide panel vibration damping while still achieving the overall weight reduction they need.

Damping Materials

SikaDamp® solutions comprise a broad family of vibration damping deadeners based on elastomers or bitumen, which can also be coupled with a constraining layer. Designed for best-in-class weight-to-performance ratios, while still providing industry-leading vibration damping performance, SikaDamp® can be applied at any point during vehicle assembly or be installed at the stamping location. The family of products is versatile in the application as magnetic, self-adhesive, melt-adhesive, or peel-and-stick formulations in standard and custom shapes. Placement and shape of parts can be highly tuned through laser-vibrometer analysis of the entire body panel system, which allows for targeted, cost-efficient use while achieving maximum vibration damping effect. Customized analysis and a tuned combination allow for the right product in the right place.
