The viscoelastic acrylic foam core delivers exceptional stress relaxation properties when subjected to high application loads, while maintaining tight bond-line aesthetics under normal operating conditions. Available in standard configuration with 2-sided silicone-coated red branded polyethylene liner, or in T-version with red polyethylene liner on one side and clear 2 mil liner on the other for PSA tabbing applications. The 1.14 mm thickness provides optimal balance between conformability and structural support for demanding automotive environments.
This product is engineered for a wide variety of temperature and humidity conditions, meeting and exceeding OEM requirements and specifications. It eliminates the need for surface pre-treatment methods and adhesion promoters, enabling significant process simplification in manufacturing operations. The tape is suitable for applications including sensor brackets, fascia, glass trim, body side moldings, claddings, pillars, wheel arch extensions, and various aftermarket accessories.
