Description
Methyltriacetoxysilane (MTAC) is a clear to yellowish liquid with an acrid odor reminiscent of acetic acid (vinegar). It is a chemical compound that hydrolyzes in the presence of moisture, releasing acetic acid and forming silanols. These silanols can then react with themselves to produce siloxanes or bind to inorganic substrates, making MTAC a versatile compound with various applications across different industries.
Uses
Used in Adhesive Industry:
Methyltriacetoxysilane is used as a coupling agent for promoting strong adhesion between inorganic substrates and organic polymers. Its ability to form siloxanes and bind to inorganic substrates enhances the durability and strength of adhesives.
Used in Coatings Industry:
MTAC is used as a crosslinking agent for improving the chemical and mechanical properties of coatings. By reacting with silanols, it forms siloxanes that contribute to the overall stability and performance of the coating.
Used in Composite Materials:
Methyltriacetoxysilane is used as a reinforcing agent in the production of composite materials. Its ability to bind with inorganic substrates and form siloxanes improves the overall strength and durability of the composite.
Used in Electronic Industry:
MTAC is used as a protective coating for electronic components due to its ability to form siloxanes, which provide a stable and durable barrier against environmental factors such as moisture and chemicals.
Used in Textile Industry:
Methyltriacetoxysilane is used as a finishing agent to improve the water repellency and soil release properties of textiles. Its interaction with silanols and inorganic substrates enhances the durability of these properties on the fabric.
Used in Construction Industry:
MTAC is used as a sealant and waterproofing agent in the construction industry. Its ability to form siloxanes and bind to inorganic substrates creates a strong, water-resistant barrier that protects structures from moisture and other environmental factors.
Flammability and Explosibility
Notclassified
Check Digit Verification of cas no
The CAS Registry Mumber 4253-34-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,2,5 and 3 respectively; the second part has 2 digits, 3 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 4253-34:
(6*4)+(5*2)+(4*5)+(3*3)+(2*3)+(1*4)=73
73 % 10 = 3
So 4253-34-3 is a valid CAS Registry Number.

Silicone-barium titanate composites with increased electromechanical sensitivity. the effects of the filler morphology
Bele,Cazacu,Stiubianu,Vlad
, p. 58522 - 58529 (2014)
A high molecular weight polydimethylsiloxane-α,ω-diol, synthesized in the lab, was used as a matrix for nanocomposites. Barium titanate nanoparticles, either cubic or nanorods, were obtained by a hydrothermal procedure and used as a filler. In order to ensure a good compatibility with the matrix, the filler was surface treated with a commercial surfactant. A highly reactive trifunctional silane was used as crosslinking agent in the presence of organometallic catalyst. Two other samples, the first consisting of pure crosslinked polydimethylsiloxane and the second being the polymer matrix filled with commercial barium titanate, were prepared and used as references to evaluate the influence of the presence of barium titanate nanoparticles and their shape on some characteristics of the resulting crosslinked composites: morphology, thermal behavior, moisture sorption, mechanical and dielectric characteristics. The electromechanical sensitivity and energy output were calculated on the basis of appropriate experimental data in order to estimate the potential of the composites for future electromechanical applications.
Preparation of acyloxysilanes
-
, (2008/06/13)
Acyloxysilanes are prepared by the anhydrous reaction of stoichiometric amounts of a carboxylic acid with a mixture of a halosilane and a silazane in an aprotic solvent, such as diethyl ether, acetonitrile, tetrahydrofuran or toluene, in an inert gas atmosphere. In a preferred embodiment the silazane is prepared in situ by the reaction of the corresponding halosilane and ammonia. No catalyst is necessary and the reaction preferably is performed at a temperature of -5° C. to 45° C.
