Long Description
Avery Dennisonβ’ OF 2429 is a high-technology, self-adhesive product specifically developed for specialized industrial applications. It is part of Avery Dennisonβs advanced range of materials commonly used in the medical, optical, and security sectors.
Construction & Design
OF 2429 features a heat-sensitive film that is coated with a blue acrylic adhesive, offering balanced performance between tack, adhesion, and cohesion.
The product is supplied on a white silicone-coated calendered paper liner for stable processing.
It provides moderate tack, medium adhesion, and high cohesive strength, ensuring secure placement with minimal residue.
Designed for clean application and protection, especially on optical lenses during the manufacturing process.
Typical Applications
Primarily used in the optical industry for lens fastening and surface protection during grinding, polishing, and handling.
Suitable for temporary bonding applications where moderate adhesion and clean removability are required.
