Description
Avery Dennison™ HPA™ 1905W – High-Performance Acrylic Adhesive Tape
Avery Dennison™ HPA™ 1905W is a high-performance, unsupported acrylic adhesive transfer tape engineered for applications requiring exceptional holding power under stress and load. This tape is particularly suitable for nameplates, membrane touch switch assemblies, graphic overlays, and other applications where high temperature, chemical, UV, and moisture resistance are critical.
The tape features a polyethylene-protected liner for ease of handling and die-cutting, combined with a specially formulated acrylic adhesive that ensures consistent bonding performance on a wide variety of substrates. Its moisture-stable, die-cut-friendly construction allows smooth removal during application, while maintaining excellent long-term adhesion and environmental resistance.
Key Features and Benefits
Unsupported acrylic adhesive for high-performance bonding
Polyethylene-protected liner for easy handling and die-cutting
High chemical, UV, moisture, and temperature resistance
Facilitates slitting, conversion, and smooth application
Excellent holding power on a wide range of substrates
