These unique products are especially formulated friction modifiers that reduce considerably traffic noise, curve squeal and rail head loads, without negative influence on the traction or braking performance. The special pastes are based on synthetic oils as well as special, solid-containing high-performance additives, are thus easily biodegradable and highly effective against noise generation. This multiple tested and approved lubricant series meets the required criteria for traction/breaking and prevents significantly noise generation and curve squeal.
