Acidic silicone adhesive, also known as aquarium glue, is a type of single-component silicone adhesive. Silicone adhesives, or more commonly known as aquarium adhesives, come in various types, generally categorized into two types: acidic and neutral.
Due to their acidic nature, they emit an unpleasant odor, but they also exhibit high resistance to temperature changes. They are produced in various colors for sealing wet areas. Neutral silicone adhesives, another type of silicone adhesive, do not have an unpleasant smell. Mirror and decorative adhesives fall under the category of neutral silicone adhesives. It is also worth noting that silicone adhesives provide excellent thermal insulation, enhancing their effectiveness.
Silicone adhesives are applicable at both high and low temperatures. Due to their chemical structure, they are highly resistant. This product, also known as aquarium glue, is utilized for sealing, offering resistance to moisture, water infiltration, and extreme temperatures. Therefore, it’s often used in sealing building glass, edges of tiles, installing sinks and washbasins, joints in restrooms, and various surfaces such as stone, glass, plastic, metal, and more.
What is Silicone Adhesive?
Silicone adhesive is a type of silicone-based adhesive widely used across various industries. It has unique properties that distinguish it from other polymer adhesives, such as high resistance to temperature, humidity, UV rays, and corrosion. These characteristics allow silicone adhesive to be used in diverse conditions, ensuring optimal performance.
Silicone adhesive can bond to various surfaces, including metal, plastic, glass, ceramics, and wood, making it versatile. It is composed of a silicone base, which acts as the adhesive agent. Alongside, it includes other materials like catalysts, reinforcers, and anti-adhesive substances. These combinations give silicone adhesive its unique properties, enabling it to bond effectively to diverse surfaces.
Features of Silicone Adhesive
Silicone adhesive possesses various properties that set it apart from other adhesives. Some of these features include:
- Temperature Resistance: This product demonstrates excellent resistance to extreme temperatures, functioning well within a range from approximately -50°C to 200°C.
- Water Resistance: It exhibits considerable resistance to water, allowing it to perform effectively in moist or aquatic environments.
- Insulating Properties: In addition to bonding, the adhesive can serve as an insulator, making it suitable for applications like waterproof doors and windows, electrical and electronic connections, plumbing, and construction.
- Flexibility: Due to its high flexibility, it can withstand the expansion and contraction of the surfaces it adheres to.
- Strong Adhesion: This type of adhesive has a very high bonding strength, which is why it is widely used across multiple applications.
- UV Resistance: It also provides good protection against ultraviolet radiation.
Moreover, silicone adhesive offers features such as flexibility, high adhesion, lack of stickiness to non-adhesive surfaces, and resistance to chemicals. Due to these attributes, silicone adhesives find extensive application in industries like electronics, automotive, medical, and construction.
Applications of Silicone Adhesive
Given its strong bonding capabilities and resistance to chemicals, moisture, and air, silicone adhesive has numerous applications. One of the most common uses for silicone adhesives is for major repairs around the home, such as sealing cracks.
Water-resistant silicone sealants are ideal for repairing areas around kitchen sinks and other places likely to encounter water. However, silicone adhesive is not suitable for heavy-weight applications, and many construction jobs require high adhesion. Window glass is often bonded to frames using silicone adhesive due to its water and weather resistance.
Typically, silicone sealants are used to bond surfaces such as plastic, metal, and glass to each other. It is important to note that aquariums are often sealed and bonded using silicone, and this should be specified on the product label. Not all silicone adhesives are suitable for aquariums, and they must be aquarium-safe to ensure they do not harm fish.
Because silicone can maintain its adhesive properties at high temperatures, it is commonly used in automobiles, electronic devices, and household appliances.
Silicone adhesives are frequently used as a bonding agent for parts in automobile engines, such as gaskets, colloquially known as gasket sealants. An example of a gasket sealant is Tesla’s silicone adhesive. In household appliances and electronic devices, silicone is utilized to secure cables and sensors in place.
Types of Silicone or Aquarium Adhesives
Silicone adhesives can generally be divided into two categories: neutral and acidic. Additionally, they can be classified into thermal and heat-resistant types, mirror adhesives, and others.
- Neutral Silicone Adhesive: This single-component adhesive requires a temperature range of 5 to 40 degrees Celsius and humidity between 5 to 95% for curing. The drying time varies based on the thickness; thicker applications take longer to dry. It can be used for various applications, including bonding plastic, metal, glass, concrete, and brick. Special formulations can also be utilized in the aerospace and aircraft manufacturing industries.
- Acidic Silicone Adhesive: Acidic silicone adhesive is produced by combining silicone with a solvent; aquarium glue is among the most recognized types. Acidic adhesives can be single or two-component and are used for sealing and decorative applications in cabinetry.
- Thermal Silicone Adhesive: This adhesive can withstand high temperatures well. Thermal and heat-resistant silicone can resist vibrations and shocks, protecting sensitive components from impact and vibration. Applications for thermal silicone adhesive include connecting components such as valves and fuel pumps in vehicles, as well as sealing various gaskets and insulation cables.
- Mirror Silicone Adhesive: As the name indicates, mirror silicone adhesives are used for bonding mirrors to various surfaces. Their unique feature ensures that when applied to a mirror, they do not damage the mirror’s reflective coating, which can otherwise degrade over time if unsuitable adhesives are used.
Conclusion
Silicone adhesive is a highly versatile polymer adhesive used across various industries. Made from silicone materials, it boasts unique characteristics such as resistance to high and low temperatures, heat, light, and chemicals.
Types of silicone adhesives include single-component, two-component or acidic, thermal and heat-resistant silicone, and mirror silicone adhesives. You can confidently use the silicone adhesives produced by “Ana Shimi Araz” for both household and industrial applications, ensuring quality and value.
