New adhesive launches as Dow Silicones and DuPont showcase Compamed portfolio

Dow Silicones has launched its new Dow Corning MG7-1020 soft skin adhesive at this year’s Compamed.

The company claims it is the highest adhesion in the company’s soft skin adhesives portfolio, plus extended wear – all without the skin irritation and discomfort more commonly associated with the removal of acrylic adhesives.

Dow Silicones and DuPont are featuring their combined portfolio of silicone elastomers, adhesives and fluids at this year’s show in Dusseldorf.

The two companies have experience in materials research, application development, technology innovation and regulatory compliance as they aim to help customers to explore new design directions in drug delivery devices and wearable technologies.

Compamed attendees can learn more about these materials at the Dow Silicones/DuPont exhibit, located in hall 8A at stand M27 throughout the show – which lasts until Thursday.

Marie Crane, global medical device leader, Dow Silicones, said: “Dow Silicones’ growing array of silicone-based materials – such as the new soft skin adhesive we’re launching here at Compamed – have been proven safe and beneficial in many different healthcare applications. Our continuous innovation in silicone adhesives is enabling development of new wearable devices, while advances in liquid silicone rubber, such as selective adhesion onto resin substrates, opens new design opportunities. In conjunction with DuPont specialty polymers, our joint technologies offer tremendous versatility for device manufacturers.”

Also featured are additional products that offer diverse adhesion levels. Each are two-part, platinum-catalysed, filler-free silicone elastomers and adhesives, designed for a range of applications in medical device fabrication, wound care and transdermal drug delivery.

The company is also exhibiting two pressure-sensitive adhesives (PSAs) for non-sensitizing, non-irritating adherence of medical devices. Dow Corning MG7-2402 and Dow Corning MG7-2502 adhesives offer biocompatibility, high adhesion and skin conformity, and extended wear time.

Dow Silicones is showing several applications for its QP1 family of liquid silicone rubbers (LSRs) that will demonstrate the versatility of these materials in the injection moulding process.

DuPont is displaying applications that use its Zytel polyamide (PA), Crastin polybutylene terephthalate (PBT) and Delrin polyoxymethylene (POM) engineering thermoplastics. These include applications such as surgical devices and self-administrated drug delivery systems.

DuPont specialty polymers offer dimensional stability combined with resistance to creep. In addition, grades are available that combine low friction and high wear resistance making them suitable for ratchets and gear mechanisms such as in healthcare delivery devices.

Michael Johnson, global R&D director for healthcare, lubricants and fluids at Dow Silicones, said: “On their own, DuPont specialty polymers deliver critical properties required for demanding healthcare device applications. When these thermoplastics are combined with Dow silicones elastomers, adhesives and fluids, the benefits to our customers can be exponential. These synergies will be increasingly valuable as designers look for unique combinations of materials to support breakthroughs in monitoring and treatment technologies, such as wearables and wirelessly connected devices.”
