Description

Alpha Nichigo G-Tape™ 3045 Series is a self-adhering flashing tape engineered specifically for bonding and seaming rubber-based materials. Constructed with a laminated polyethylene cloth backing and a proprietary acrylic adhesive, it delivers strong adhesion on low surface energy substrates where conventional flashing tapes often fail.

Designed for demanding exterior applications, Nichigo G-Tape™ 3045 Series combines high static shear strength, clean handling, and all-weather performance to support reliable sealing on rubber sheets, membranes, and related assemblies.

Key Features

  • Engineered for Rubber Seaming: Designed to seam and splice rubber sheets with high static shear strength.
  • Excellent Adhesion to Rubber: Bonds effectively to low surface energy materials, including EPDM rubber.
  • Laminated Polyethylene Cloth Backing: Provides added strength, flexibility, and handling control during installation.
  • Hand-Tear Application: Tears straight by hand with no cutting tools required.
  • Scrap-Less Face-to-Face Handling: If the adhesive contacts itself during installation, it can be separated cleanly without damaging performance.
  • Repositionable During Application: Allows adjustment without wrinkling for cleaner seams.
  • Replacement for Asphalt and Butyl Tapes: Offers a cleaner, more controlled alternative for rubber flashing applications.
  • All-Weather Performance: Maintains adhesion in temperatures from -40°F to 176°F.
  • AAMA Certified Performance: Meets AAMA 711-13 Type A (without primer), Level 3, and AC 148 requirements.
