DEHESIVE® 971 is 100 %, completely solventless, addition-curing silicone intended for coating paper and other substrates. Special features: - exceptionally fast, low temperature cure
- higher release at low peel speeds
- low release at high peel speeds
- flat release profile
- good release stability
- good bath life
- solvent-free
- extremely fast cure properties of DEHESIVE® 971 allow for a very low platinum concentration
- flat release profile of DEHESIVE® 971 guarantees easy matrix stripping and label dispensing in label applications
- DEHESIVE® 971 can be combined with conventional multifunctional DEHESIVE® polymers, which in general have a flat release profile at a higher release level. This avoids crossing over of release profiles in double sided tape applications.
Application: DEHESIVE® 971 is solvent-free silicones with an oily consistency and good flow properties. It is especially suitable for solvent-free paper coating. Other substrates can be rendered non-stick towards pressure-sensitive adhesives with this product, e.g. metallic tapes and plastic sheets. DEHESIVE® 971 develops optimum release properties once it has undergone complete crosslinking. Subsequent postcuring - which is needed for most condensation-crosslinking silicones - is not necessary.Information provided by Wacker Chemie AG. |
