Silicones or siloxanes - Applications

A particular family of silicones, combining resins, reactive oils or gums, cross-linking agents and specific catalysts, is used for the surface treatment of flexible cellulose or synthetic substrates (paper, film, textiles, etc.) to provide water repellency and anti-adhesion properties.

The silicone layer must be firmly bonded to the substrate in order to withstand high abrasion and friction forces, and the risk of stripping after swelling by solvents. Layer thickness is generally between 0.5 and 1.5 µm (semi-continuous coating on substrate).

• The main areas of application are as follows:

  • protection against adhesive materials: self-adhesive labels, hot-melt packaging, bitumen packaging, envelopes, feminine hygiene articles, baby diapers with adhesive strips, bandages,...
