Specification of 1, 3-Divinyl-1, 1, 3, 3-Tetramethyl Disilazane 7691-02-3 Acting as a Coating Additive
This chemical is 1,3-Divinyl-1,1,3,3-Tetramethyl Disilazane. Its CAS number is 7691-02-3. It is a liquid silazane compound. It is used as a special additive in coatings. Its main job is improving how coatings stick to surfaces and perform.
It has reactive vinyl groups (-CH=CH₂) attached to silicon atoms. It also has methyl groups (-CH₃). The silicon-nitrogen bond in its core is key. This structure gives it useful properties for modifying coatings.
Adding this chemical to coatings helps a lot. It makes surfaces much more water-repellent. Water beads up instead of soaking in. This protects the coated material better. It also helps the coating stick very well to difficult surfaces like glass, metals, or plastics. This prevents peeling or flaking later. The coating becomes more durable against scratches and chemicals. It can handle tougher conditions.
It works by interacting with the coating material itself. The vinyl groups can react during curing. They help form a stronger, more cross-linked network. This makes the coating harder and tougher. The molecule also migrates towards the coating surface. It aligns its hydrophobic parts outward. This creates the water-repelling effect. It acts like a bridge between the coating and the substrate. This improves adhesion significantly.
You need to handle this chemical carefully. It is flammable. Store it away from heat and sparks. Keep it sealed tightly. Moisture in the air can make it react. Use it in a place with good airflow. Wear protective gloves and glasses. Follow all safety guidelines on its label. It is usually added in small amounts during coating formulation. The exact amount depends on the specific coating and desired result. It is compatible with many common coating systems.

Applications of 1, 3-Divinyl-1, 1, 3, 3-Tetramethyl Disilazane 7691-02-3 Acting as a Coating Additive
1,3-Divinyl-1,1,3,3-Tetramethyl Disilazane (CAS 7691-02-3) is a useful silane additive for many coating systems. Its special structure gives it key benefits. The molecule has vinyl groups. These groups can react. They bond chemically with other materials. This happens during curing or application. The disilazane part helps the molecule interact well with surfaces.
One main use is surface modification. This silane easily attaches to inorganic surfaces. Think glass, metals, or minerals. It forms a strong, covalent bond. This bond changes the surface energy. It makes the surface more compatible with organic coatings. The result is much better adhesion. Coatings stick strongly. They resist peeling or delamination. This is vital for long-lasting performance.
Another key effect is increased hydrophobicity. This silane makes surfaces water-repellent. Water beads up and rolls off. This protects the coated material. It stops water damage. It reduces staining. It also helps prevent corrosion on metal substrates. Keeping water out is crucial for durability.
This additive also works well inside the coating itself. It helps disperse fillers and pigments. It prevents these particles from clumping. Good dispersion means a smoother, more uniform coating film. The coating looks better. Its protective properties are more consistent across the surface. It avoids weak spots.
The vinyl groups offer another advantage. They can take part in the coating’s curing reactions. They link directly into the polymer network. This makes the silane a permanent part of the coating. It doesn’t leach out over time. Its benefits last. This integration improves the coating’s mechanical strength. It also boosts chemical resistance.
You find this silane in various coatings. Industrial protective coatings use it. Automotive paints use it. Electronic encapsulants use it. Marine coatings use it. Anywhere strong adhesion and water resistance are needed, it helps. Its ability to bridge organic and inorganic phases is powerful. It solves common coating problems effectively. Using it leads to tougher, more reliable finishes.
