Avery Dennison™ OF 2475 – Heat-Sensitive Optical Protection Film
Avery Dennison™ OF 2475 is a high-technology self-adhesive film developed for precision applications in the optical, medical, and security industries. This product features a heat-sensitive carrier film coated with a blue, solvent-based acrylic adhesive, offering a balanced combination of moderate tack, high cohesion, and reliable performance on various surfaces.
Engineered for temporary fastening and surface protection, OF 2475 is particularly designed for use in the optical manufacturing industry, where it provides secure adhesion and clean removability during lens processing, polishing, or coating operations. Its carefully formulated adhesive ensures stable performance without leaving residue, even after exposure to heat or cleaning solutions typically used in optical production environments.
Key Features
Heat-sensitive film construction offering excellent control and removability.
Solvent-based blue acrylic adhesive with moderate tack and high cohesive strength.
Calendered paper liner ensuring stable processing, storage, and die-cutting performance.
Moderate adhesion properties suitable for a wide range of industrial substrates.
Engineered for high precision optical applications, especially lens protection and mounting.
Benefits
Clean, reliable adhesion for temporary bonding on glass, metals, and plastics.
High cohesion and dimensional stability, preventing film deformation during processing.
Resistant to water, detergents, and alcohol, ensuring performance through multiple cleaning cycles.
Good balance between tack and removability, reducing the risk of residue or substrate damage.
Controlled activation temperature, making it ideal for thermal or heat-assisted processes.
Supports efficient die-cutting and handling, improving conversion performance.
Typical Applications
Optical industry: fastening, masking, and protecting lenses during cutting, grinding, or coating.
Medical and laboratory devices: protective or bonding layers requiring clean removability.
Security and identification films: applications requiring controlled adhesion and heat activation.
Precision industrial uses where temporary adhesion with residue-free removal is required.

Application Techniques
Surfaces should be clean, dry, and free of grease or contaminants prior to application.
Bond strength depends on adhesive contact area, pressure, and temperature during application.
For optimal results, adjust pressure, dwell time, and application temperature to substrate type and surface texture.
