NuSil Adds 2 New Drug Delivery Silicones
New silicone adhesive.
Carpinteria, CA — NuSil Technology LLC has added two new transdermal adhesives to its comprehensive Drug Delivery Silicone (DDS) line of materials for drug delivery and combination medical devices. DDR-1370 is a traditional pressure-sensitive adhesive (PSA), and DDR-4355 is a silicone gel with superior tack. Both the PSA and gel can be applied using coating processes, but represent two different options when selecting a temporary, transdermal adhesive.

DDR-1370 is a one-part, non-curing, traditional PSA dispersed in ethyl acetate. This material has a typical viscosity of 1,450 cP and, once coated onto a substrate, can be die cut into various shapes and sizes. It has high cohesive strength and high release force, resulting in favorable temporary adhesive properties. DDR-4355 is a transparent, silicone tacky gel with a typical viscosity of approximately 15,000 cP. It cures at low temperatures to a soft, high-surface-tack, temporary silicone adhesive. These Drug Delivery Silicones can be customized for specific applications to control the release of a wide range of Active Pharmaceutical Ingredients (APIs). In addition, the company can compound APIs directly into silicones at its U.S. FDA registered, manufacturing facilities.

Regulatory support for DDR-1370 and DDR-4355 includes extensive physical, chemical and biological testing in the form of Drug Master Files (DMFs). A DMF for DDR-1370 and DDR-4355 is being filed with the U.S. Food and Drug Administration.
