WACKER Expands Line of Silicone Adhesives With New Gel for Medical Use

Adhesives, Industry News,

The company reports that it is expanding its line of silicone adhesives to include a silicone gel that adheres strongly to the skin yet allows gentle and pain-free removal. SILPURAN 2124 achieves an adhesive force of 6.0 newtons per 2.5 centimeters, determined in the 90° pull-off test on steel in accordance with EN 1639. This makes the adhesion so strong that the new gel can not only be used in wound care but is also suitable for other skin fixation applications according to the company.

SILPURAN 2124 is a transparent, two-component, low-viscosity silicone gel. WACKER reports that at 3000 millipascal seconds, it has a viscosity that is optimally matched to the coating process and enables simple and fast dosing. SILPURAN 2124 crosslinks by a platinum-catalyzed addition reaction to form a soft, highly flexible, and elastic silicone with a gel-like consistency. The cured rubber is water repellent, but breathable and gentle to the skin. 

The new adhesive gel leaves no residue on the skin when removed and fixation aids and wound dressings can be freely peeled off and reapplied, reports WACKER. The adhesive layer combines well with certain polyethylene release films, which protect the adhesive layer in the final ready-to-use product. These release films can be removed without leaving any residue before application, and the release force remains unchanged even after several months of storage.
