DowDuPont Specialty Products Division is introducing a new soft skin adhesive called DOW CORNING™ MG 7-1020, which is especially designed for today’s wearable medical devices. Based on advanced silicone technology, this unique product can be used for an extended period of time while maintaining strong adhesion and causing minimal skin irritation. The new adhesive can be used on medical pumps and patches, as well as pumpable patches for biologic drug delivery as an alternative to injection pens.

“Our continuous investment in innovative materials such as this new soft skin adhesive is designed to help medical device companies develop the next generation of skin-adhered solutions for effective, comfortable monitoring and treatment,” said Marie Crane, Global Medical Device Leader for DowDuPont Specialty Products Division. “This versatile, strong, yet gentle high-performance adhesive offers benefits to device designers, manufacturers, clinicians and patients. It can play an important role in the usability and efficacy of tomorrow’s wearable technologies and drug delivery devices.”
Ideal for Delicate Skin
The new DOW CORNING MG 7-1020 Soft Skin Adhesive is ideal for patients with delicate, compromised or sensitive skin and is specifically designed to minimize irritation, sensitizing and cytotoxicity. Its high degree of penetration into the skin surface enhances conformability and the patient experience. Further, unlike traditional acrylic adhesives, it will not cause discomfort during removal, said a press release.
Painless Repositioning
This new adhesive can used in wearable devices where patients can easily reposition their device if needed for comfort.
Flexible Design and Manufacturing
Because this new solution maintains its adhesive strength even at lower coat weights, designers can fine-tune the coating application to match desired wear and cost parameters for the device. The product can be direct- or transfer-coated onto a variety of backing substrates, including woven and nonwoven fabrics.

For manufacturers, the new DOW CORNING MG 7-1020 features a longer working (pot) life at higher ambient temperature and humidity conditions than traditional adhesives to avoid premature auto-curing, which can degrade the effectiveness of the adhesive. This two-part, low-viscosity silicone adhesive also offers fast cure rates across a wide range of temperatures.
