3M Constrained Layer Damper SJ2052 is constructed of a dead soft aluminum foil constraining layer and coated with a pressure sensitive, viscoelastic acrylic polymer adhesive. This unique construction provides the ability to control resonant vibrations in a variety of applications and across a broad spectrum of temperatures.Absorbs and Dissipates Resonate Vibration 3M Constrained Layer Damper SJ2052 is an aluminum foil backed anti-vibration tape. It is designed to reduce structure-borne noise and fatigue in metal and composite panels and support structures. With a viscoelastic acrylic polymer adhesive this tape is easy to apply and it adheres well to metal. It can achieve effective damping with as little as 20% surface coverage. This durable tape will resist moisture, weather, UV degradation and flame. It is a long aging tape designed to specifically perform in a wide variety of temperatures (-25°F/32°C to 175°F/180°C) with peak damping from 32°F/0°C to 140°F/60°C. The linered construction provides the ability to die cut this product. 3M Constrained Layer Damper SJ2052 meets the requirements of F.A.R. 25.853(a) and can pass ASTM E-162 and ASTM-E 662 for flammability and smoke generation. Recommended Applications • Aerospace, automotive, appliance and general industrial applications • Electronic equipment and appliances • Reduce unwanted resonant noise, vibration and fatigue in metal panels and support structures • Applications where plastic or metal contact with materials can result in potentially damaging vibration
