Release Coating Application
Are you a newcomer in the silicone release coating applications ? Or just looking for a better understanding of a term ? Our experts have been thinking to all of you to build this glossary !
In release coatings, silicone formulations are used for coating on a substrate, such as paper, film, or foil, to make a coating with properties that allow the release of adhesives or inherently sticky materials. This is known as a silicone release liner. The use of these silicone materials is typically within the paper, printing or converting industries. There is a general use of standard terms within these industries but on some occasions these can be unique to Silicone Release Applications.
CURE / CURING
The process of changing the structure and properties of a coating or adhesive by chemical reaction of the reactive functional groups on the polymer or other reactive components in the formulation. This change may be affected by crosslinking or polymerization initiated by UV or EB radiation, catalysts or thermal treatment at elevated temperatures.
You don’t dry an egg, you cook it – curing is a bit like that, you cook the liquid coating and it becomes dry and rubbery!
