A material and B material after mixing, stirring gently to reduce the amount of air mixed in. Perfusion material before mixing for 5 minutes, which facilitates removal when mixed with air mixing. If there is also a bubble, you need to vacuum degassing process. Taking into account the expandable material, the volume of deaeration vessel used should be at least 4 times the liquid volume. You can use a vacuum degassing process 28-30 inches Hg to remove air bubbles contained in the mixed material. Continue evacuated until the expansion of the liquid and then return to its original volume, which will eliminate all air bubbles. This process takes 5 minutes to 10 minutes range, depending on the amount of air entrained when stirred. To achieve the best curing effect, it requires the use of glassware and glass or metal mixing equipment. Try to keep steady while stirring to prevent the mixing of excess air. Pot life / operating time curing reaction starts at the beginning of the mixing process. Initially, cure is a gradual increase in viscosity, followed by gelation and conversion to a solid elastomer. Definitions applicable period after mixing the components A and B, between the viscosity increased to twice the time required for the original. Please refer to the respective silicone potting pot. Processing and curing silicone encapsulants After a thorough mixing, direct injection / dispensing container to the desired curing curing. Care should be taken to minimize the mixing of air. If feasible, especially potting and sealing element has many pores, should try gluing or dispensing under vacuum. If you can not use this process, the yuan in the use of organic silicon products potting and sealing after vacuum degassing treatment. Silicone encapsulants can be cured at room temperature (25 ℃) under heat cured. Room temperature cure encapsulants may be heated to accelerate the cure. Product selection table for each product are ideal curing conditions. Xi Shun plastic material in advance should be stirred before use, because the transport and storage process will produce partial precipitation. Surface treatment preparation applications requiring high strength and adhesion, the silicone encapsulants need to use a primer. See the Primer Selection Guide primer to match the product. For best results, the primer should be applied in a thin, uniform, and then erased. It should be thoroughly dried in the open air, using a silicone potting materials after use primer. The temperature range can be used for most applications, the silicone elastomer may be long-term use in the temperature range of -50 to 200 ℃. However, under conditions of low temperature and high temperature ends of the performance of the material in some special applications presented it will become very complicated, and therefore need to consider additional factors. Low-temperature performance, thermal cycling can be performed on at around -55 ℃ environment? But your performance parts and assemblies need to be confirmed. Factors affecting performance include configuration and stress sensitivity of components, cooling rates and hold times, and prior temperature history experienced. Xi Shun special materials such as potting elastomer can be used at -65 ℃ or lower. Under conditions of high temperature section, cured silicone elastomer durability depends on the time and temperature. As expected, the higher the temperature, the shorter the time the material can be used. Compatibility In some cases, it will not achieve the best curing effect of the product when in contact with certain plastics or rubber, use a solvent to clean the substrate surface or slightly higher than the curing temperature baking, solve this problem. Certain chemicals, curing agents and plasticizers can inhibit the curing, paying particular attention to the following materials: containing N, P, S and other organic matter and containing Sn, Pb, Hg, Bi, As and other ionic compounds. Hydrocarbons and more alkyne-containing vinyl compound. Contract type plastic materials used molds and tools, in order to avoid poisoning the platinum catalyst lose activity and can not properly cured. Fixes the manufacture of electrical / electronic equipment, are hoping to be abandoned or damaged product recycling. In the case of the internal circuit does not cause great damage, we want a non-silicone rigid potting / encapsulating materials, removal and re-perfusion is difficult or impossible. Xi Shun using silicone encapsulants can easily be selectively removed, repair or complete replacement and repair parts re-infused into the new potting. To remove silicone elastomers, simply cut with a sharp blade or knife unwanted material from the area to be repaired torn or removed. For elastomer adhered to the section on the best use of mechanical means such as scraping or rubbing method for removing from a substrate or circuit, silicone oil can be used as an adjuvant. In devices that have been repaired before refilling encapsulants, use sandpaper to the surface of the cured potting fight hair, then wipe with a suitable solvent. This will enhance adhesion and permit the repaired material with the existing cement potting integrally. Not silicone adhesive primer as the product itself. Precautions rubber skin contact rinse with soap and water, if you do not accidentally come into contact with eyes, immediately flush eyes with plenty of water for at least 15 minutes, seek immediate medical attention if pain inflammation treatment does not include this information required for safe use of the product security information.
