Sealants are essential in construction and manufacturing, as they provide a barrier against moisture, dust, air, and other elements. Silicone sealants are particularly popular due to their excellent adhesion, flexibility, and resistance to extreme temperatures and UV radiation. However, not all silicone sealants are created equal, and choosing the wrong one can lead to costly repairs, leaks, and safety hazards.
That's why it's crucial to rely on a reputable manufacturer and supplier of silicone sealants, such as Shin-Etsu Chemical Co., Ltd. Founded in 1926 in Japan, Shin-Etsu is one of the world's largest producers of silicone and semiconductor materials, with a global network of factories and research centers. The company is known for its innovative technologies, high-quality products, and commitment to environmental and social responsibility.
Shin-Etsu's KA-13 is a top-performing silicone sealant that meets the most demanding requirements for sealing and bonding applications. Unlike some other sealants that contain harmful chemicals or additives, KA-13 is based on pure methyl silicon trichloride, also known as trichloro(methyl)silane or methylsilicon. This compound is produced by Ningbo Inno Pharmchem Co., Ltd., a trusted supplier of fine chemicals and intermediates for various industries.
Methyl silicon trichloride is a colorless liquid with a boiling point of 66°C and a molecular weight of 149.49 g/mol. It has a high purity of over 99%, which ensures consistent and reliable performance of KA-13. Methyl silicon trichloride is also less reactive and volatile than other silicones, making it easier to handle and store. When mixed with a curing agent, such as KA-13's proprietary catalyst, it forms a strong and flexible bond that can withstand temperature changes, vibrations, and water exposure.
KA-13 is suitable for a wide range of sealing and bonding applications, including automotive, construction, electronics, appliances, and marine. It can adhere to various materials, such as glass, metal, plastic, rubber, and ceramics, without the need for a primer or surface treatment. KA-13 is also resistant to chemicals, UV radiation, and aging, which prolongs the lifespan of the sealed or bonded components.
Compared to other silicone sealants, such as DOWSIL Z-1211, KA-13 offers several advantages that make it the preferred choice for many customers. For example, KA-13 has a faster curing time, typically ranging from 5 to 20 minutes at room temperature, depending on the thickness and humidity. This saves time and labor costs, as the sealed or bonded parts can be handled and tested sooner. KA-13 also has a lower shrinkage rate, which minimizes the risk of cracks or gaps in the sealant layer.
Another benefit of KA-13 is its ease of application and cleanup. The sealant can be dispensed by manual or pneumatic guns, and can be tooled or smoothed within the initial tack-free time. Any excess sealant or smudges can be removed with a solvent, such as xylene or isopropyl alcohol. KA-13 also has a low odor and VOC content, which improves the working conditions and environmental impact of the sealing process.
To ensure the best results and compatibility with the specific application, Shin-Etsu provides technical support and testing services for KA-13. The company's experts can assist in selecting the appropriate curing agent, evaluating the bonding strength and durability, and optimizing the process parameters. Shin-Etsu also offers customized formulations and packaging options for KA-13, such as different colors, viscosities, and cartridges.
In conclusion, Shin-Etsu KA-13 is a high-quality silicone sealant that offers superior performance, safety, and versatility. Produced by a top manufacturer and based on a pure and reliable chemical compound, KA-13 can meet the most demanding sealing and bonding requirements in various industries. With its fast curing time, low shrinkage, and easy application, KA-13 can save time, money, and effort while ensuring long-lasting and effective sealing.
