Fabricators of Adhesive Tapes & Flexible Materials I 818-998-1477. Innovations in Bonding to Low Surface Energy Surfaces. Many engineered plastics have surface energies in this range, as do natural materials such as wood, stone or concrete. A waxed hood, however, has a lower surface energy than water. Samples are available to U.S. industrial customers only. Energy treatments are temporary—a short time after exposure, the polyolefin reverts to its original low surface energy. Low Surface Energy Adhesives are designed to bond to hard to stick to surfaces such as plastics, polypropylene, polyethylene, polystyrene, thermoplastic polyolefin's, EVA, PTFE, powder coated paints and oily metal surfaces. Molecules on the surface are so strongly attracted to each other that they will very happily be attracted to liquid molecules as well. With ongoing advances in technology, several adhesive suppliers now product structural strength adhesive specially formulated to bond LSE surfaces after simply wiping the surface clean of lose particles. The brands listed above are trademarks of 3M. Figure 1 For bonding to these difficult-to-adhere-to surfaces, FLEXcon is promoting its extensive line of These adhesive transfer tapes are self-wound thin tapes with low surface energy acrylic pressure sensitive adhesive laminated directly onto a removable liner. Historically, low surface energy plastics required some type of surface treatment such as abrasion, flame, corona, plasma, chemical treatment or primers prior to bonding. They are generally soft and have a low melting point so they’re easy to process, even at high volumes, and they’re low-density, which helps with lightweighting.

Substrates with a low surface energy can be difficult to bond to because the surface resists adhesive wet-out, leaving poor surface contact and low adhesion. However, high strength adhesives have high surface energy. Adhesives suitable for use with low surface energy materials are described. 3M takes your privacy seriously. The low surface energy simply prevents conventional adhesives from making intimate contact with the substrate surface and this reduces adhesion. 3M™ 300LSE Low Surface Energy Acrylic Tapes and 3M™ Scotch-Weld™ Structural Plastic Adhesive DP8010 Blue are two examples of adhesives designed to bond to some LSE substrates without a primer. While finding solutions for better bonding in these substrates, the joint interface becomes the overriding concern. Do not use on platicized vinyl. “Wetting out” means the adhesive flows and covers a surface to maximize the contact area and the attractive forces between the adhesive and bonding surface. On a low surface energy substrate an adhesive … Adhesives suitable for use with low surface energy materials are described. For traditional structural adhesives to bond low surface energy substrates such as polyolefins, surface treatments have been used to raise the substrate surface energy by as much as 30% to better meet the adhesive surface energy. Disclaimer: The 3M Industrial Sample Request Program is not available to consumers or the general public. You will be contacted to verify your request. The adhesive contain an acrylic copolymer, a high glass transition temperature tackifier and a low glass transition temperature tackifier. They bond well to most substrates including difficult to bond low surface energy plastics and powder coated paints. This category includes old technologies like glass, ceramics and concrete as well as natural materials like wood, leather and fabric. Figure 3 - Surface Treatment Effect on Surface Energy. To achieve a strong bond, substrates must be treated with a primer prior to adhesive application. Wetting becomes a challenge when using conventional adhesives to bond these low surface energy (LSE) substrates. However, the same properties that make polypropylene good for containing hot water and battery acid also make it difficult to bond with adhesives. The surface energy of materials can be classified into three groups: high, medium and low surface energy. Low surface energy adhesive . When seeking to manufacture a plastic-based part, there are more options for attaching parts together than ever before. These include polyolefin plastics such as polypropylene and polyethylene as well as “non-stick” surfaces such as polytetrafluorethylene (PTFE). While surface preparation techniques help increase the level of surface energy, new adhesive formulation advancements enable adhesives to bond to these materials with or without surface preparation. As a result, these materials are relatively easy to wet out and, in turn, to bond. On a high energy surface substrate an adhesive ows providing a better bond. Adhesives suitable for use with low surface energy materials are described. measured by dynes per centimeter, surface energy measures the attraction between unlike surfaces. Low Surface Energy (LSE) Tapes. Traditional Materials are relatively easy to bond, but each one has its own considerations. Everything is relative. Acrylics will bond to many MSE substrates but may benefit from using a primer to increase adhesion. Instant adhesives or cyanoacrylates are the most commonly used adhesives for bonding polyolefin plastics. Adhesive contacts of complex shape begin to detach at the "edges" of the contact area. Adhesives suitable for use with low surface energy materials are described. Ultimately, elastic adhesives lead to a faster, safer and more durable bond. Somewhere between perfectly wet-out films and perfectly spherical droplets, we define medium surface energy. The more surface wets out, the smaller the contact angle Zisman’s equation (Figure 2 provides an empirical relationship relating the contact angle to the difference between the surface energies of the substrate and liquid). Low Surface Energy Adhesives are designed to bond to hard to stick to surfaces such as plastics, polypropylene, polyethylene, polystyrene, thermoplastic polyolefin's, EVA, PTFE, powder coated paints and oily metal surfaces.

The formulation, polymerization, and performance of a new class of low‐surface‐energy adhesives for plastics are described. Low Surface Energy Adhesive Transfer Tapes. There is very little attraction to any molecule, especially adhesive molecules. High surface energy materials have surface energies on the order of 100s or 1000s of dynes/cm and include many metals and glass. How Adhesives are Adapting to Low Surface Energy Materials. Some people believe that “low surface energy” means it will stick to anything that is low surface energy. Understanding why some plastics are so difficult to bond will help you optimize the surface and joint design. For gaskets that are required to stick to those surfaces, sometimes a low surface energy adhesive transfer tape is a good solution. Low-surface-energy materials are increasingly being used in durable product manufacturing due to the cost-effectiveness of the materials. For optimum adhesion, an adhesive needs to be thoroughly ‘wet out’ on the substrate to … Supplied with either 2 mil (3M467) or 5 mil (3M468) adhesives.

Figure 3 shows the effect of various surface treatments on polyethylene. • AdhesaFoil – Thin aluminum foil labels • Thickness of 3 mil & 5 mil foils. Low Surface Energy means the tape is better at sticking to lower surface energy substrates, but primers are still required for certain substrates such as silicone rubber. Innovations in Bonding to Low Surface Energy Surfaces. This is due to their formulation’s ability to adjust to a lower surface energy. If you do not consent to this use of your personal information, please do not use this system. Thus, their application is problematic for low energy materials such as polymers. We will respond to your email request in 24 - 48 business hours. Following are a review of some plastic adhesives as well as tricks of the trade to bond virtually anything. Energy treatments are temporary—a short time after exposure, the polyolefin reverts to its original low surface energy. How Adhesives are Adapting to Low Surface Energy Materials. There is very little attraction to any molecule, especially adhesive molecules. Polymers for Advanced Technologies 2012 , 23 (7) , 1077-1083. Materials with low surface energy (LSE) do not allow adhesives to wet out, while materials with high surface energy (HSE) provide excellent wet-out, providing the best adhesion. To achieve a strong bond, substrates must be treated with a primer prior to adhesive application. On a high energy surface substrate an adhesive ows providing a better bond. Strong adhesive can replace screws, rivets and welding; 3M™ Scotch-Weld™ Structural Plastic Adhesive DP8010 Blue is a two-part acrylic adhesive specially formulated to bond many low surface energy plastics, including many grades of polypropylene, polyethylene, and thermoplastic elastomers (TPEs) without special surface preparation. This is a broad and varied group: basically it includes lots of things that have higher surface energies than plastics but lower surface energies than metals. The surface energy values of some typical materials are shown in the two tables. An error has occurred while submitting. Thank you for your interest! These low surface energy materials stick together and repel liquids, making them difficult to bond. Adhesive / Substrate Miscibility Another adhesion theory, the diffusion theory, can be of help in choosing adhesive systems for low surface energy polymers.The fundamental concept of the diffusion theory is that adhesion arises through the inter-diffusion of molecules from one material to another across the interface. Many adhesives are specifically formulated for low surface energy surfaces. Another factor determining the strength of an adhesive contact is its shape. Custom Adhesive Products (CAP) is a developer and supplier of high performance pressure sensitive tapes.By forming a strong partnership with our customers, we’re able to provide innovative and cost effective solutions for a wide array of tape applications, such as splicing tape, flying splice tape, silicone splicing tape, butt splicing tape, PTFE tape and more. Adhesives suitable for use with low surface energy materials are described. This happens when the surface energy of the substrate is greater than the surface energy of the adhesive. A lower surface energy material, such as water, will spontaneously wet out a higher energy surface, such as the un-waxed hood of a car. Please be aware that this information may be stored on a server located in the U.S. Most adhesives and tapes will adhere to most metals, so any time you’re bonding metal you have a wide range of adhesive options. LSE substrates can be very challenging to bond and often require specially designed adhesives and/or surface treatments and primers to get a good bond. Low Surface Energy Molecules on the surface of low-surface-energy materials are quite happy the way they are. The term W 12 is a surface energy term which is obtained via Eq. Low-surface-energy materials are increasingly being used in durable product manufacturing due to the cost-effectiveness of the materials. Visit the. Low surface energy materials such as polyethylene, polypropylene, polytetrafluoroethylene and polyoxymethylene are difficult to bond without special surface preparation. Surface energy affects an adhesive’s ability to ‘wet-out’ or spread over the substrate. Wetting can be measured by the contact angle of a bead of liquid on the surface (figure 1). The adhesive contain an acrylic copolymer, a high glass transition temperature tackifier and a low … The adhesive contain an acrylic copolymer, a high glass transition temperature tackifier and a low glass transition temperature tackifier. Wetting becomes a challenge when using conventional adhesives to bond these low surface energy (LSE) substrates. For optimum adhesion, an adhesive must thoroughly “wet out” the surface to be bonded. Polyurethane (urea)/polyacrylates interpenetrating polymer network (IPN) adhesives for low surface energy materials. They have very high surface energies and they’re open to contact with liquids and thus very easy to wet out. The Massetak Low Surface Energy Adhesive Kit, or ‘LSE’ kit for short, has been rigorously developed to bond even the most difficult of materials including plastics and thermoplastic rubbers like PTFE, polypropylene (PP) , polyethylene (PE) silicone rubber, TPV—all of which require special chemical surface treatments to Supplied with 3M 300 Low Surface Energy adhesives. To achieve a robust bond in any joining application, good surface contact is required between the adhesive and substrates; the adhesive must spread across or “wet out” the plastic surface. Specialty adhesives have been formulated which provide very high strength adhesion to low surface energy plastics such as polypropylene and polyethylene, and good strength on PTFE. This technology is intended to help meet design and production challenges by effectively bonding polyolefins while saving the time and expense of priming or more complex surface treatments such as corona discharge. In the past Low Surface Energy (LSE) plastics, such as Thermoplastic Polyolefin (TPO), Polypropylene (PP), and Polyethylenes (e.g. Low-surface-energy materials are increasingly being used in durable product manufacturing due to the cost-effectiveness of the materials.
