Permabond 910 Directions for Use They are incompatible with acids; mixing nitriles with strong oxidizing acids can lead to extremely violent reactions. Table 42.5. This is the most basic installation technique, and care must be taken when choosing the strain gage itself. It is used in adhesives and in dentistry. A research student working under Coover synthesised ethyl cyanoacrylate, and, in trying to measure the compound’s refractive index, accidentally stuck two glass prisms together. Thus, strong acids or materials that can become strong acids upon the addition of water can be used to stabilize cyanoacrylates. These adhesives also work well for Kydex sheet to PVC and ABS applications. Lightly scrub the area where the glue is stuck to the fabric and brush it for several minutes. The number of cyanoacrylate monomers is relatively limited. Figure 7. The initiator (I−) attaches to a cyanoacrylate. Medical grade cyanoacrylate topical skin adhesive is used effectively for closing wounds, termed liquid bandaging. Parts are fragile direct from the process. Permabond® ET5441 is a thermally conductive, two-component adhesive based on epoxy resin. Therefore, materials such as sulfonic acids or sulfur dioxide have been used. They have also been used to assemble medical devices. From: Handbook of Plastics Joining (Second Edition), 2009, P. Klemarczyk, J. Guthrie, in Advances in Structural Adhesive Bonding, 2010. Light and moisture are known to accelerate the polymerization process. Cyanoacrylate adhesives should be stored in cool, dark and dry conditions. Generally, ethyl cyanoacrylate forms stronger, more durable joints to rubber and other flexible substrates; methyl cyanoacrylate adhesives produce slightly higher joint strengths with rigid plastics and metals [1, 3, 7, 14]. The based adhesives by IPS work well for Kydex sheet applications. Minimal degradation is possible outdoors, depending on the substrate; however, exposure to severe temperatures, solvents (water, acetone, alkaline solutions), or weathering will produce bond weakening and eventual collapse.

Cyanoacrylate adhesives are colorless, one-part, room-temperature-curing adhesives that are available in viscosities ranging from water-thin liquids to thixotropic gels. Toughening of cyanoacrylates can also be a problem. An in vivo animal study, using the butyl-based adhesive Indermil®, reported no deterioration in the strength, pliability or usability of adhesive using opened vials over the course of 28 days.29 In addition, no apparent microbial contamination was noted. At this point, the strain gage is bonded to the component and is ready for the next step, which is lead wire attachment. It is also widely used in orthopedic and dental applications. Permabond 101 is an ethyl cyanoacrylate which forms strong bonds to most plastics. It is a single part, low viscosity liquid that will cure rapidly at room temperature when pressed into a thin film between parts. Porous substrates such as wood, paper and leather require the use of products containing accelerators. UV Curable For difficult or porous surfaces using a Permabond activator is recommended. The usual addition of an elastomer to a structural adhesive can be attempted for cyanoacrylates, but in many cases such addition can lead to premature gelation of the formulation due to processing aids that were added to the elastomer. Cyanoacrylate adhesive products are usually based on the ethyl ester but methyl, n-butyl, allyl, β-methoxyethyl and β-ethoxyethyl are also important. Nitriles may polymerize in the presence of metals and some metal compounds. It is sometimes desirable not to seal the strain gage coupon on all four sides with the tape. Reference: Carver TG, Kubizne PJ, Huys D: Reaction injection molded modular window gaskets using light stable aliphatic polyurethane. Methyl Methacrylate Adhesives, or MMAs, are structural adhesives that have been developed to bond metals, plastics, and composites. Aside from the properties mentioned it should be noted that ethyl type cyanoacrylates are dissolved by acetone, methyl ethyl ketone, nitromethane and dimethylformamide. Accuracy is dependent on binder droplet size, powder size, the diffusion of the binder into the powder, and printer head positional resolution. They are especially suitable for smaller areas of application, where a very fast cure is desired. 1 oz Bottle. A suitable coating must be installed as well in order to seal the installation from the environment and also to provide some mechanical protection. Cyanoacrylates have also been used in surgery during wartime. An amine can often be the initiating species. As with any adhesive, surface preparation is important. Robertson, ... B.R. The interior package surface must be neutral or slightly acidic, impermeable to water, and allow for multiple adhesive uses. Surface Preparation prior to bonding with Permabond 910 Special precautions should be observed when handling cyanoacrylates; one needs to consult the manufacturer for details [1]. High temperatures are known to decrease the viscosity of the adhesives and may compromise efficacy. This adhesion is retained over a wide range of temperatures and after lengthy ageing under heat and humid conditions. Alkyl cyanoacrylate monomers and polymers were first reported in 1949.34 The first commercialization of the technology was done by Tennesee Eastman Co., which resulted in Eastman 910.35 This adhesive was noted for its very rapid cure and high room temperature lap shear strength. 4,5-Dimethyl-2-oxo-1,3,2-dioxathiolane is a liquid with a boiling point of 185 °C.

Cyanoacrylate adhesive products are usually based on the ethyl ester but methyl, n-butyl, allyl, β-methoxyethyl and β-ethoxyethyl are also important. The main materials in use are ethyl and methyl cyanoacrylates. Advantages and disadvantages of cyanoacrylate adhesives, F.P. Other catalysts can be sprayed over a drop of free cyanoacrylate for curing, a method used for tacking wires or small components in electrical assemblies [1, 3, 7]. Acetone: The Anti-Super Glue . Given the high reactivity of cyanoacrylate adhesives, creating packaging which is unreactive toward the adhesive is critical in obtaining a reasonable shelf-life for commercial products. Swift, J.D. General purpose cyanoacrylates form brittle joints with high shear and tensile strengths and can withstand temperatures from –54°C (–65°F) up to about 82°C (180°F) at low humidity, and indoors show no significant changes over a number of years. The adhesive was later called ‘Super-Glue™’. Thermal stabilizers also have to be added if the use of the adhesive is to reach temperatures in excess of 120 °C; thus materials such as a cyclic sulfate have been added to minimize the thermally induced depolymerization reaction.37 Cyanoacrylates are also known to be sensitive to the surface on which they are applied. 3M Scotch-Weld Plastic & Rubber Instant Adhesive PR40, Clear 4.5 out of 5 stars 215. 4) Do not disturb or re-align until sufficient strength is achieved, normally in a few seconds.

It is important to realize that this adhesive does not work well for structural use and should be only used as a cosmetic adhesive. “Blooming” or “frosting”, which can occur when general purpose cyanoacrylates volatize, react with moisture in the air and settle on the part, can be eliminated by using special “low-odor/low-bloom” cyanoacrylates with lower vapor pressures [3, 7]. The polymerization ensues until a terminating species (T+) terminates the reaction. What are the best plastic to metal adhesives? Not particularly suitable where an accurate fit is required for the part due to relatively poor tolerances and strength. When pressed into a thin film between two surfaces, cyanoacrylates cure rapidly to form rigid thermoplastics with excellent adhesion to most substrates (plastics, metals, rubber, wood, skin, etc.) METHYL 2-CYANOACRYLATE is an unsaturated aliphatic nitrile and acrylate ester. The stability of a cyanoacrylate adhesive in storage can be improved by the addition of small amounts of a stabilizer. Permabond has a history of developing and manufacturing engineering ... ©2016 Permabond LLC. Plasticizers have also been added to reduce the effect of gradual embrittlement. Pretreatment of polymers usually involves cleaning in a non-solvent and optional surface abrading. Ethyl cyanoacrylate is the monomer which is most widely used in both consumer and industrial applications, because of its combination of fast cure speed and ease of manufacture. Then, warm about 1 cup of vinegar in the microwave for about 15 to 20 seconds and gently brush that onto the glue. Recently, octyl cyanoacrylate has been found to be a noninflammatory liquid suture.41, In Handbook of Plastics Joining (Second Edition), 2009. Some of these products contain additives such as fumed silica to make them more viscous or rubber to make them more impact resistant. Find the most up-to-date version of FORD WSK-M2G401-A3 at Engineering360. Fixture times for low viscosity adhesives are lower than for those with higher viscosity. The shelf life of uncured adhesive is about one year in polyethylene or metal containers; exposure to humidity and ultraviolet light shortens shelf life, while refrigeration extends it. Most packages are composed of polyolefins, such as polyethylene or polypropylene, which are free of any basic contamination from stabilizers, processing aids, or mold release. Permabond 910 is the original 100%-methyl cyanoacrylate adhesive. The majority of super glues are either methyl or ethyl cyanoacrylate based. These properties make PERMABOND cyanoacrylates the ideal adhesives for high-speed production lines. Cyanoacrylate adhesives are unique in that they bond rapidly and easily to a variety of substrates. The resulting enolate anion acts as a nucelophile and attacks the electrophilic carbon on the formaldehyde. General stress analysis applications can also utilize the higher quality and higher capability of heat cured epoxy adhesive systems that are more commonly utilized in transducer applications. Each type has its own characteristics. Methyl cyanoacrylate is less commonly encountered than ethyl cyanoacrylate. Primers, or adhesion promoters, are substances with chemical structures that promote strong adhesive properties (surface tension effects, dipole interactions) when applied in very thin films.
