What you need to know about neutral cure silicone

You’ve probably heard of neutral cure silicone, but have you ever wondered what it is? This article will give you the scoop on this non-corrosive product if you’ve never heard of it. This product dries within 10 to 20 minutes and has a stronger smell than neutral cure silicone. If you’re planning to use it for any interior design project, you should know some of its benefits before you buy it.

Neutral cure silicone is non-corrosive

Silicone is a versatile, pliable material used in a variety of industries. It has extensive adhesive properties and bonds with a wide variety of substrates. Unlike other adhesives, it is non-corrosive to metals. It also does not release a pungent odor during the cure. Its tack-free time is long and has high heat and oil resistance. 

Although acetoxy silicones are the most popular type of sealant, their high cost limits their application and can lead to premature failure. However, neutral cure silicone is an excellent choice for exterior applications because it is non-corrosive and doesn’t produce a strong acidic scent. It makes it a preferred material for sealing the edges of mirrors. If you’re concerned about the smell of acetoxy silicones,100% silicone by bostik.com is the perfect option.

Among the benefits of neutral cure silicone, it can help protect the metal from corrosion and is ideal for vehicle use. This type of silicone also releases a non-corrosive substance during curing. It has almost no odor. It can be used for various applications, including metal roofing and weatherproofing trucks and caravans. It is also suitable for outdoor activities, including boating.

It cures in 10-20 minutes

The main difference between a neutral cure and a platinum cure is the time needed for the sealant to dry fully. The former cures quickly, while the latter takes longer. While a warmer room will speed up the process, a humid environment will cause the sealant to dry more slowly. In addition, direct heat will reduce the silicone’s longevity, so the more humid your room is, the longer the curing process will take.

For exterior applications, neutral cure silicone is an excellent choice as it does not create an acidic environment when it cures. Because of this, it’s best used on materials already damaged by acetoxy sealants. In addition, neutral cure silicone is more durable against weather, making it ideal for exterior uses. It also has a longer dry time than acetoxy silicone. You should always check the label before applying it to ensure that you use the right product for the job.

It has a stronger smell

While oxyme-cure silicone adhesives have a strong odor, the more neutral-cure variety does not. The latter is less sensitive to humidity, which can reduce the strength of the adhesive bond. It makes neutral-cure silicone a better choice for glass paint applications. Both types of silicone adhere to surfaces using a process known as convection curing. Although acetoxy and neutral-cure silicones have similar characteristics, they have distinct differences. Acetoxy-cure silicones release acetic acid during the curing process, while neutral-cure silicones have no smell and do not require additional curing compounds. 

In addition to being a better choice for many applications, acetoxy-cure silicones have a stronger odor. When cured, they also give off a vinegar-like smell and can cause a foul odor on some surfaces. They tend to be faster-curing than neutral-cure silicones but can damage delicate electronic components.

However, many articles on caulking materials have misleading titles, and it cannot be easy to make an informed decision. Although both are highly useful, the advantages of each type are different, and their uses and environments are quite other. If you’re wondering which is better, consider comparing both types. If you’re looking for a suitable sealant, you can choose between acetoxy and neutral-cure silicones.

The disadvantages of both types of silicones lie in their smells. Acetoxy-cure silicones release acetic acid when curing, which can cause problems on certain types of substrates. Natural stone may develop color polarity, while metal shapes exhibit bubbles and bleeding. Despite its smell, this type of silicone is better suited for outdoor applications. For this reason, most manufacturers recommend neutral-cure silicones.

Both RTV and neutral-cure silicones have different properties. Acetoxy-cure silicones are faster to cure and have shorter tack-free times. However, oxime-cure silicones take longer to cure and have a stronger smell. It also requires a primer. So, if you want silicone that can bond to concrete, go with the neutral-cure variety.
