Chemistry of release coatings

Most self-adhesive products like labels and tapes require a release coating to protect the adhesive layer prior to its use. The release coating usually comes on a carrier called the release liner. Self-adhesive tapes may have a release layer on the backside. The release performance contributes substantially to the conversion properties of a self-adhesive product and therefore require attention. Today, various release systems are available, dominated by silicone types. The aim of this paper is to explain the main differences between common release systems with a view on chemistry and the required coating and curing technology.
