Most people who know about RTV silicone don’t know that there are actually two types available. Like some other heavy-duty adhesive substances, RTV silicone is available in a single-part version and a two-part version, both of which are equally as effective. RTV silicone sealant is easy to work with and can easily fit in a number of containers. This is part of the reason that it can either be applied manually or it can be squeezed out of a long tube using a silicone applicator. RTV silicone sealant also has a distinct almost pungent smell that makes it easily identifiable in virtually any environment. RTV silicone has the properties of, well, silicone. It’s relatively dense with a gelatinous consistency while wet, which turns into a rubbery consistency once dry. The chemical properties of RTV sealant are pretty much the same as we mentioned previously. RTV is pretty durable when put up against everyday forces, it isn’t super viscous, doesn’t absorb moisture when dry, and isn’t really reactive with any other chemicals. Again, this makes it the ideal adhesive and sealant. RTV silicone isn’t very dense or particularly strong, but it is pretty robust and is capable of taking quite a bit of punishment. This is because of its rubberized nature which allows the substance to distribute force quite well, whether it be impact and/or abrasion. RTV sealant has a number of other properties that make it sought after as well.

Chem. 2012, vol. 26, 157–163. doi: 10.1002/aoc.2832 As we mentioned previously there is no such thing as the perfect material, and RTV silicone is no exception to the rule. With that being said, RTV silicone isn’t perfect for every occasion, so let’s have a look at some instances where you might want to have a look around and see what other adhesives and/or sealers are available to you. RTV silicone is one of the most versatile adhesives and sealers on the market. It can be used as a building sealer, an industrial adhesive, an engine mount press fitting, to create medical implements, and even to create cutlery. a b c Lorenz, Günter, and Andreas Kandelbauer. “14 - Silicones.” Handbook of Thermoset Plastics. Third Edition. Elsevier Inc, 2014. 555–575. Web.Single-part silicone tends to cost a bit more because it’s a bit more convenient to use, but it’s no better than its two-part counterpart.

The adhesive qualities of RTV silicone are pretty good too, allowing this type of silicone to hold workpieces of varying materials together indefinitely in some cases. The CHT patented Acetone and the Alkoxy range of 1 and 2-part RTV silicone adhesive sealants are safe to use within electronics. They can be used to bond components on a PCB and they will not damage sensitive metals, such as copper. The range includes MIL specification products and thermally conductive silicone for the fast-effective transfer of heat.Once the two parts are combined in the ration instructed by the manufacturer they will cure and eventually vulcanize into the same durable silicone as the one-part version.

Unscrew cap, pierce end and apply nozzle supplied, cut nozzle cleanly at an angle of 45° with an opening slightly Single-part RTV silicone is best used for time-sensitive projects and or as an emergency repair tool. Note:These sealants were not designed for and should not be used for applications involving permanent implantation into the human body. They are not for use in delicate electrical and electronic applications corrosion of copper, brass or other sensitive metals is undesirable. Product Code If you thought the safe temperature range of the RTV silicone was impressive, you’re going to love finding out that not only is it also resistant to the effects of corrosive chemicals but RTV silicone is also resistant to the effects of UV light. This means that it can be easily cleaned, and your workpiece can be left in direct sunlight without you having to worry about damage.The 3145 90ML from Dow Corning is a RTV clear adhesive/sealant for electrical and electronic applications. RTV sealant has a decent shore hardness, an average tensile strength, isn’t very easy to tear or penetrate, and can be used on a wide variety of materials. Aside from being resistant to the effects of chemicals and UV light, RTV silicone is also pretty tough. Being resistant to the effects of impact and abrasion, many materials are coated with RTV silicone to increase their ability to absorb large amounts of force without compromising their structural integrity.
