Black, non-drying, non-curing synthetic rubber based on butyl rubber with high viscosity and stability. Key benefits - Provides a durable, permanent seal for automotive glazing and lighting assemblies. - Maintains a water seal over time, helping to prevent leaks at joints and seams. - High viscosity supports stable placement and reduces squeeze-out during installation. - Remains flexible in elastic areas, absorbing movement between glass and metal. - Simple, straightforward installation with no curing or drying required. - Black color blends with automotive components and resists visible staining. Material and performance - Material: synthetic rubber based on butyl rubber - Color: black - Viscosity and stability: high viscosity, stable formulation - Drying/curing: non-drying, non-curing - Seal quality: permanent seal and water seal when used in appropriate joints Typical applications - Used as a placement sealing tape for re-sealing headlights after servicing or installation - Can be installed between glass and metal in headlight assemblies and related areas - Suitable for elastic areas of car headlights and windscreens to maintain a durable water seal Use scenarios - Scenario 1: resealing a headlight after a lens replacement or headlight service to prevent water ingress - Scenario 2: forming a glass-to-metal seal at headlights and relevant windscreen interfaces where flexibility is needed - Scenario 3: sealing elastic joints around headlights and windscreens that experience vibration and movement while maintaining a permanent water seal
