Reliable Protection Of Sensitive Components And Circuits Using Dow Corning 3145
In electronics industry, protection of sensitive components and circuits is important for sustenance of the electrical and physical properties for a wide range of operating conditions. For this purpose, bonding and sealing is extensively used throughout the industry of electronics. A product of Dow Corning that is widely used for the protection of sensitive and critical components is Dow Corning 3145 RTV MIL-A-46146 Adhesive Sealant.
 Dow Corning 3145 silicone adhesives for Engineering Application. |
Dow Corning 3145 Adhesive Sealant is a non-flowing adhesive that is available in paste form. It consists of one part moisture cure providing magnificent features of improved thermal stability, elongation and high tensile strength. The available versions of Dow Corning 3145 are gray and translucent and it is UL94 V-0 and MIL-A-46146 recognized. In particular, 3145 Gray is better for applications based on high temperature while it is useful for applications that include Mil Spec requirements. It has a slight odor and long-term exposure could cause slight irritation to respiratory passages during inhalation. |
Some high performance engineering applications features about Dow Corning 3145 Adhesive Sealant
There are a few remarkable features that make Dow Corning 3145 Adhesive Sealant the best choice of every customer. It cures at room temperature with 30 to 80 percent humidity in the environment excluding the need of ovens and energy cost. Improved thermal stability offered by the adhesive sealant makes it unique for a wide range of high temperature applications. Mixing is not required for this sealant and the in-line processing is faster with heat acceleration that could be an option. It has a shelf life of 12 months with storing temperature at 25°C.
The complete physical properties greater than 90 percent can be attained within 24 to 72 hours time that varies depending on the product. Manufacturing through put is achieved faster; however the selection of adhesive and the applied amount can take shorter time within 10 to 120 minutes. Typically, Dow Corning 3145 Adhesive Sealant is not used in spaces that are highly confined or where deep section cure is required since exposed surface inward cure is required at a rate of 0.25 inch per 7 days. The progress of cure starts from outer exposed surface and depends on the air moisture. In general, surface skin of adhesive product begins to form within an hour and therefore, a few minutes to an hour could be the working time for such products. The cure can be accelerated for increasing the throughput by providing mild heat below 60°C (140°F).
The service life and reliability of electronic components and devices are enhanced with the use of Dow Corning silicone adhesives. Dow Corning 3145 Adhesive Sealant has versatile options of processing and stable chemistry. It helps in obtaining numerous benefits for various needs of electronics that include reduction in total cost, increased reliability and safety of component and enhanced performance of modules and devices.
Some of the potential uses of Dow Corning 3145 Adhesive Sealant include assembly of yoke and components on PWBs, sealing of electrical and wired leads, mechanical stability added to components and sealing of openings in housings and modules. The typical method for application of this adhesive sealant requires manual or automated needle dispense system.
