DOWSIL Z-6403: The Ultimate Solution for High-Performance Coatings
In the world of coatings, achieving high-performance and durability is always a top priority. This requires the use of advanced materials that can provide excellent adhesion, water resistance, and overall protection against harsh environmental conditions. One such material is DOWSIL Z-6403, a versatile and reliable silane coupling agent that is widely used in the coatings industry.
Manufactured and supplied by INNO SPECIALTY CHEMICALS in China, DOWSIL Z-6403 is an isobutyltriethoxysilane that belongs to the family of organosilanes. It is a clear, colorless liquid with a molecular weight of 222.38 g/mol and a boiling point of 175-177 °C. Its chemical formula is C10H24O3Si, and its CAS number is 17980-47-1.
DOWSIL Z-6403 is a highly efficient coupling agent that can improve the adhesion of coatings to a wide range of substrates, including metals, glass, ceramics, and plastics. It works by bonding chemically with the substrate surface and creating a strong interfacial adhesion between the coating and the substrate. This results in a more uniform and durable coating that can withstand various stresses, such as mechanical abrasion, thermal cycling, and exposure to chemicals and moisture.
One of the key benefits of DOWSIL Z-6403 is its ability to enhance the water resistance of coatings. This is particularly important in outdoor applications where coatings are exposed to rain, humidity, and other forms of water exposure. By forming a hydrophobic layer on the substrate surface, DOWSIL Z-6403 can prevent water from penetrating the coating and causing damage or delamination.
Another advantage of DOWSIL Z-6403 is its compatibility with a wide range of coating resins, such as epoxies, polyurethanes, acrylics, and alkyds. This allows it to be used in various coating formulations and systems, providing flexibility and versatility to coatings manufacturers. Moreover, DOWSIL Z-6403 can also improve the rheological properties of coatings, such as viscosity, flow, and leveling, which can lead to better application and appearance.
To achieve optimal performance, DOWSIL Z-6403 should be used at a recommended dosage of 0.5-3% based on the total weight of the coating formulation. It can be added at any stage of the coating production process, including during grinding, mixing, or letdown. It is also recommended to use DOWSIL Z-6403 with a suitable catalyst or accelerator, such as dibutyltin dilaurate or zinc octoate, to facilitate the silane coupling reaction.
In terms of safety and handling, DOWSIL Z-6403 is a relatively low-toxicity substance that should be handled with proper care and protection. It is flammable and should be stored in a cool, well-ventilated area away from heat sources and ignition. It should also be kept away from children and animals and disposed of according to local regulations.
In conclusion, DOWSIL Z-6403 is a high-performance silane coupling agent that can significantly improve the adhesion, water resistance, and durability of coatings. Its versatility, compatibility, and efficiency make it a popular choice among coatings manufacturers worldwide. As a trusted supplier of DOWSIL Z-6403 and other advanced materials, INNO SPECIALTY CHEMICALS is committed to providing innovative solutions and excellent service to its customers.
