Information About Dow Corning ® brand Adhesive/SealantsSilicones and ElectronicsLong-term, reliable protection of sensitive circuits and components is important in many of today’s delicate and demanding electronic applications. Silicones function as durable dielectric insulation, as barriers against environmental contaminants and as stress-relieving shock and vibration absorbers over a wide temperature and humidity range.In addition to sustaining their physical and electrical prop-erties over a broad range of operating conditions, silicones are resistant to ozone and ultraviolet degradation, have good chemical stability and are available in a variety of useful forms as conformal coatings, encapsulants and adhesives.Dow Corning’s broad range of general purpose and specialty products offers you a choice of materials for your application needs.Dow Corning offers a variety of noncorrosive silicone products for electronic sealing, bonding and adhering applications. These adhesives generally fall into three cure types. The first group are moisture cure, generally meant for room-temperature processing. The second type(condensation cure) offers rapid room-temperature and deep-section curing. The third type is heat cure for rapid processing. All convert to durable, relatively low stresselastomers. Most will develop good, primerless adhesion to a variety of common substrates including ceramics, reactive metals and filled plastics.TYPICAL PROPERTIESThese values are not intended for use in preparing specifications.Specification Writers: Please obtain copies of the Dow Corning Sales Specifications for these products and use them as a basis for your specifications. They may be obtained from any Dow Corning Sales Office, or from Dow Corning Customer Service in Midland,MI. Call (517) 496-6000.HEAT CURE TIMESCURE CONDITIONSOne-Part Moisture Cure RTVThe one-part moisture cure adhesives (838, 839, 3165, 3145,3140 and 3-1744) are generally cured at room temperature and in a range of 30 to 80 percent relative humidity. Greater than 90 percent of their full physical properties should be attained within 24 to 72 hours depending on the product chosen. Materials and parts can be handled in much shorter times of about 10 to 120 minutes depending on the product chosen and the amount of material used per part. These materials are not typically used for highly confined or deep section cures. Materials will generally cure about 0.25 inch per seven days from any exposed surface. Cure progresses from the outer surface and is dependent on the moisture in the air. Working time is generally a few minutes to an hour for these products until a surface skin begins to form. Mild heat acceleration of the cure rate may be possible but temperatures above 60°C (140°F) are not recommended.Two-Part Room Temperature Condensation CureDow Corning ® Q3-6093 Silicone Adhesive is the only two-part condensation curing product. Once mixed, cure progresses rapidly at room temperature. Good strength is attained within an hour but full properties are not reached for anumber of days. Q3-6093 adhesive contains its own source of moisture and cure progresses evenly throughout the material.Deep section or confined cures are possible however (see “Reversion”). Working time is only a few minutes.Heat CureThe addition curing adhesives (577, 3-6876, 3-6611 and 3-6265) should be cured at 100°C (212°F) or above. The cure rate is rapidly accelerated with heat (see cure schedulesin table). For thicker sections or if voiding is observed, a 30 minutes pre-cure at 70°C (158°F) may reduce voids in the elastomer. Addition-curing materials contain all the ingredients needed for cure with no byproducts from the cure mechanism. Deep section or confined cures arepossible. Cure progresses evenly throughout the material.These adhesives generally have long working times.PREPARING SURFACESAll surfaces should be thoroughly cleaned and/or degreased with Dow Corning ®brand OS Fluids, naphtha, mineral spirits,methyl ethyl ketone (MEK) or other suitable solvent.Solvents such as acetone or isopropyl alcohol (IPA) do not tend to remove oils well, and any oils remaining on the surface may interfere with adhesion. Light surface abrasion is recommended whenever possible, because it promotes good cleaning and increases the surface area for bonding. A final surface wipe with acetone or IPA is also useful.Different cleaning techniques may give better results than others. Users should determine the best techniques for their applications.ADHESIONDow Corning silicone adhesives are specially formulated to provide unprimed adhesion to many reactive metals,ceramics and glass, as well as to selected laminates, resins and plastics. However, good adhesion cannot be expected on nonreactive metal substrates or non-reactive plastic surfaces such as Teflon ®, polyethylene or polypropylene. Special surface treatments such as chemical etching or plasma treatment can sometimes provide a reactive surface and promote adhesion to these types of substrates. Dow Corning ®brand primers (see “Primer Selection Guide”) can be used to increase the chemical activity on difficult substrates.2P5200 Red is a low-VOC alternative to 1200 Red.3P5204 is a low-VOC alternative to 1204.4The lower VOC value is for states and air quality management districts that have recognized volatile methylsiloxanes as VOC exempt.PRIMER SELECTION GUIDEThese values are not intended for use in preparing specifications.Poor adhesion may be experienced on plastic or rubber substrates that are highly plasticized, because the mobile plasticizers act as release agents. Small-scale laboratory evaluation of all substrates is recommended before production trials are made.In general, increasing the cure temperature and/or cure time will improve the ultimate adhesion.SUBSTRATE TESTINGDue to the wide variety of substrate types and differences in substrate surface conditions, general statements on adhesion and bond strength are impossible. To ensure maximum bond strength on a particular substrate, 100 percent cohesive failure of the adhesive in a lap shear or similar adhesive strength test is desired. This ensures compatibility of the adhesive with the substrate being considered. Also,this test can be used to determine minimum cure time or can detect the presence of surface contaminants such as mold release agents, oils, greases and oxide films.USEFUL TEMPERATURE RANGESFor most uses, silicone elastomers should be operational over a temperature range of -45 to 200°C (-49 to 392°F) for long periods of time. However, at both the low and high temperature ends of the spectrum, behavior of the materials and performance in particular applications can become more complex and require additional considerations.For low-temperature performance, thermal cycling to conditions such as -55°C (-67°F) may be possible, butperformance should be verified for your parts or assemblies.Factors that may influence performance are configuration and stress sensitivity of components, cooling rates and hold times, and prior temperature history.At the high-temperture end, the durability of the cured silicone elastomer is time and temperature dependent. As expected, the higher the temperature, the shorter the time the material will remain useable.COMPATIBILITYCertain materials, chemicals, curing agents and plasticizers can inhibit the cure of addition cure adhesives. Most notable of these include:•Organotin and other organometallic compounds •Silicone rubber containing organotin catalyst •Sulfur, polysulfides, polysulfones or other sulfur-containing materials•Amines, urethanes or amine-containing materials •Unsaturated hydrocarbon plasticizers •Some solder flux residuesIf a substrate or material is questionable with respect to potentially causing inhibition of cure, it is recommended that a small scale compatibility test be run to ascertain suitability in a given application. The presence of liquid or uncured product at the interface between the questionable substrate and the cured gel indicates incompatibility and inhibition of cure.MIXING AND DE-AIRINGUpon standing, some filler may settle to the bottom of the liquid containers after several weeks. To ensure a uniform product mix, the material in each container should be thoroughly mixed prior to use.1Clear only.2Gray only.3UL746C Approved.LISTINGS AND SPECIFICATIONSDow Corning Corporation Midland, Michigan 48686-0994Dow Corning and Sylgard are registered trademarks of Dow Corning Corporation.Teflon is a registered trademark of E.I. du Pont de Nemours Co.©2000 Dow Corning Corporation. All rights reser ved.Printed in USAAGP4781Form No. 10-911A-01Two-part materials should be mixed in the proper ratio (1:1or 10:1) either by weight or volume. The presence of light colored streaks or marbling indicates inadequate mixing.Automated airless dispense equipment can be used toreduce or avoid the need to de-air. If de-airing is required to reduce voids in the cured elastomer, consider a vacuum de-air schedule of >28 inches Hg for 10 minutes or until bubbling subsides.REVERSIONWhen two-part condensation curing materials with organo-tin catalysts, such as Q3-6093 adhesive, are cured in confinement (especially in deep section) and are later subjected to high heat conditions, can potentially revert back from a cured elastomer to a flowable polymer.Although this condition is unusual, parts using Q3-6093adhesive should be thoroughly tested in accelerated temperature conditions for this potential limitation.SOLVENT EXPOSUREWhen liquid or vapor solvent or fuel exposure can occur in an application, the silicone adhesives discussed in thisbrochure are intended only to survive splash or intermittent exposures. They are not suited for continuous solvent or fuel exposure. Testing should be done to confirm performance of the adhesives under these conditions.STORAGE AND SHELF LIFEShelf life is indicated by the “Use Before” date found on the product label.For best results, Dow Corning RTV adhesives should be stored at or below 25°C (77°F). Special precautions must be taken to prevent moisture from contacting these materials.Containers should be kept tightly closed and head or air space minimized. Partially filled containers should be purged with dry air or other gases, such as nitrogen.Dow Corning heat-cure adhesives should also be stored at or below 25°C (77°C). Containers should be kept tightly closed and kept in cold storage at all times to extend shelf life.LIMITATIONSThese products are neither tested nor represented as suitable for medical or pharmaceutical uses.PACKAGINGIn general, Dow Corning adhesives/sealants are supplied in nominal 0.45-, 3.6-, 18- and 200-kg (1-, 8-, 40- and 440-lb)containers,net weight.
