CROWN EPT® (Acrylic Foam Tape) for Reliable Automotive Weatherstrip Bonding

As new energy vehicles gain popularity, automotive lightweighting advances, and vehicle designs evolve, automotive sealing systems are increasingly required to deliver enhanced acoustic comfort, greater design precision, and long-term durability.

Designs such as frameless doors, panoramic sunroofs, and streamlined body contours place higher demands on weatherstrip profile conformity, assembly precision, and gap control. Meanwhile, bonding rubber and elastomer substrates, managing sustained stress from weatherstrip rebound, and achieving reliable adhesion on complex curved surfaces present additional challenges for adhesive materials, requiring strong adhesion, flexibility, and durability.

To address bonding requirements for automotive weatherstrips and other components, CROWN EPT® (Acrylic Foam Tape) features a soft, resilient foam structure with excellent conformability and bonding performance. It provides reliable bonding solutions for complex assemblies, stress absorption, and durable automotive component integration.
