Sticky material, usually polymer based, that bonds one substance to another. Specific performance characteristics can be engineered into the formula.
The carrier supports and serves as a backing for the adhesive, providing reinforcing strength and dimensional stability, and contributes to the final properties of the product. Depending on the application, film, foam or nonwoven materials are commonly used.
Usually coated with a cured siliconized release material for ease of separation, it is the material to which the adhesive is applied. The release liner is paired with a specific adhesive to promote ease of release and application. Transfer tapes (no carrier, adhesive with a release liner) are available for specific applications.
