Silicone release coatings for hygiene applications

Elkem's SILCOLEASE™ silicone system can be applied quickly and efficiently at low coat weights on low grammage paper and polyolefin films, to give unique processing advantages including heat-sensitive substrates.

The use of adhesives can be a key factor to the design and function of many self-adhesive applications found in the hygiene market. For example, the ease of (re-)attachment for a diaper tape can help a struggling parent or an aging adult, while the slim profile and soundless opening of a feminine sanitary pad allows for discretion in everyday use.  

Silicone release coatings are used in the construction of these hygiene products, which are often multi-layered. Most of the time, these very thin layers of silicone release coatings are applied on off-line coaters. Highly compatible with many different adhesive technologies, they can provide the ideal way to protect the adhesive until it is ready to be used.
