Advances in adhesives and ease- of- use make pressure- sensitive adhesives (PSAs) the number one choice for medical devices that must be temporarily attached to a patient's skin, such as transdermal patches and ECG electrodes. But PSAs can also use multi- lamination materials to simplify assembly of medical devices. Unlike liquid adhesives, PSAs are typically supplied in ready to use sheets, rolls, or die cut forms, and can be supplied in precise, uniform coating thicknesses adjusted to the application. Another plus is that PSAs require no activation by water, solvent, or heat to bond with a substrate. Bonding assemblies. Pressure- sensitive adhesives, as the name implies, adhere to most materials immediately when applied with light to moderate pressure. Bonds build to predesigned levels over short periods. PSAs make it relatively fast and easy to bond several materials into a laminate, and these can be similar or dissimilar materials, such as those that are stiff and flexible, hard and soft, and thick and thin. Today's medical market provides a wide variety of ready- to- use PSA coated films, foams, and fabrics. PSAs balance adhesive flow and resistance to flow. A bond forms because the adhesive is soft enough to flow, or wet out, onto another substrate. But the bond is strong because the adhesive is hard enough to resist flow with applied stress. Furthermore, PSAs are said to be in dry form, meaning they have little or no solvent or water retention and are tacky at room temperature. So users should allow time for proper bonding, especially when dealing with materials that are difficult to bond together, such as low- surface energy substrates. These include polyethylene, polypropylenes and PTFE films, or silicones, polyurethanes, fiberglass pads, and ether foams. While some applications require internal or functional bonds, others have more specialized requirements. Take skin contact and in- vitro diagnostics, for example. Tapes for use on the skin in devices such as electrodes, ostomy bags, and surgical grounding pads must meet all FDA or local government regulations, and should be tested to government standards as well as thoroughly tested in the actual application. For in- vitro diagnostics (IVD), pressure- sensitive adhesives should be formulated to produce a chemically inert adhesive system that will not migrate into sample pads or membranes. The PSA should be an acrylic biocompatible with components of the test with no affect on the stability of reagents or membranes. Building a PSA tape. Pressure- sensitive adhesives often come in the form of tapes and generally in three options: Double- coated tapes come on a carrier, such as polyester or other film, coated on both sides with a PSA and protected by one or two release liners. Single- coated tapes come on a carrier, such as a film, foam, or woven material, which is coated on one side with a PSA and protected by one release liner. Transfer (unsupported) tapes use a layer of PSA coated onto a protective release liner without additional support or backing. To protect the adhesive before and during assembly, a protective release liner must be placed over the adhesive. The liner can be paper or film treated for release characteristics and moisture resistance. The release agent is typically a silicone coating that makes it easy to remove the liner from the adhesive. A few considerations. PSA carriers, sometimes referred to as backings, are used for single- coated and double- coated applications. A wide range of substrates, such as foam, film, woven, and non- woven, are available from most manufacturers and converters. Foam, soft and conformable for user comfort, is die cut easily into various shapes and sizes. It may also be printed on. A range of thicknesses, colors, and types are available. Films can be thin and highly conformable or thicker and shield devices or skin from moisture. Transparent films allow visual monitoring without removing tape, and breathable films let air and moisture pass. Perforated films may be hand torn and improve a moisture vapor- transmission rate (MVTR), while those that are printable can carry use instructions. Woven fabric is often used for wound care. The soft and flexible fabric is easily die cut into various shapes and sizes and is typically printable. Woven materials come in a wide range of colors and in various thicknesses, typically from 0. Blends of natural and synthetic materials are also available. Nonwoven materials such as tissues, spun- lace polyester, polyester blends, rayon, and other fabrics are lightweight, and often breathable. Some nonwoven fabrics can be embossed to let air and moisture pass. They are easily die cut into various shapes and sizes, and a soft backing makes for patient comfort. Where PSAs work well. A few conventional tasks for PSAs include bonding, sealing, mounting, device assembly, adhering a device to skin, and wound care. A few less than conventional applications include: EMI (electromagnetic interference) shielding that provides a pathway for stray RF signals around the doors of electronic enclosures. Sound damping to reduce structure- borne noise is done through the viscoelastic properties of the adhesive, or the substrates they are laminated to, or both. Vibration damping uses damping adhesives on both sides of the foam, film, or paper carrier to reduce vibration and absorb shock, especially in medical and electronic devices. Thermal conductivity calls for loading the PSAs with particles to enhance heat transfer within a device. When bonding to metal or plastic, thermally conductive PSAs can draw heat away from delicate components. Electrically conductive PSAs can be formulated or loaded with particles to enhance electrical conductivity for laminating and assembling electrodes, grounding conductive cushioning pads, and defibrillation applications. In Vitro Diagnostics (IVD) bond lateral and vertical flow components such as nitrocellulose membrane and absorbent and conjugate pads to a rigid plastic backing for IVD test strips. PSAs are also used in biosensors to create channels for sample flow, as well as laminating film layers and other components together. Transdermal drug delivery mixes drugs and therapeutic materials directly into the adhesives or uses a reservoir and membrane controlled laminate. It bonds to the skin with a single coated adhesive patch or bandage.
