Product Background	t-Butyl methacrylate, commonly abbreviated as TBMA or T-BMA, is a key organic chemical monomer with the CAS Registry Number 585-07-9 and the molecular formula C₈H₁₄O₂, corresponding to a molecular weight of 142.20. It is formally named as "2-propenoic acid, 2-methyl-, 1,1-dimethylethyl ester" in systematic chemical nomenclature, and is also widely known by synonyms such as tertiary-butyl methacrylate, methacrylic acid tert-butyl ester, and tert-butyl methacrylate monomer. In its pure form, t-Butyl methacrylate presents as a colorless liquid under standard conditions (20°C). Due to its inherent reactivity as an acrylate monomer, commercial-grade TBMA is typically stabilized with MEHQ (monoethylhydroquinone) to prevent unwanted polymerization during storage and transportation. This stabilization ensures the product maintains its monomeric form and reactivity until ready for use in industrial or research processes. With a well-documented presence in the global chemical market, t-Butyl methacrylate falls under the category of organic chemical raw materials and complies with regulatory frameworks such as Japan’s Chemical Substance Law (ENCS) with the classification number 2-1039. Its unique molecular structure—featuring a bulky tert-butyl group attached to the methacrylate ester backbone—distinguishes it from other acrylate monomers and endows it with a suite of properties that make it indispensable in polymer synthesis and specialty chemical manufacturing.
Product Features	Distinctive Physical and Chemical Traits: It is a colorless liquid with low flash point and vapor pressure, soluble in most organic solvents while only slightly soluble in water. This solubility profile expands its compatibility with various formulation systems. High Purity Benchmark: Commercial supplies of t-Butyl methacrylate typically meet strict purity standards, with minimum purity levels of 98.0% (as measured by gas chromatography, GC) and premium grades reaching up to 99.5%. Additionally, it adheres to tight quality controls for impurities, such as a maximum water content of 0.1% and a color (APHA) rating of 20 or lower. Controlled Reactivity: As a methacrylate monomer, it readily undergoes homopolymerization and copolymerization reactions. Its reactivity is precisely modulated by MEHQ stabilization, ensuring safe handling and consistent performance in synthesis. Unique Structural Influence: The presence of the tert-butyl group in its molecular structure directly contributes to its high glass transition temperature (Tg) and resistance to chemical reactions like transesterification, setting it apart from structurally simpler methacrylates.
Product Applications	Coatings Industry: It is a critical component in acrylate coatings for automobiles, construction, and furniture. It enhances the coatings’ water resistance, weatherability, and hardness, ensuring long-lasting protection and aesthetics. It also finds use in paper coatings and painted coatings, as well as in formulations for industrial coatings. Adhesives Sector: As an important monomer for pressure-sensitive adhesives and structural adhesives, it supports bonding applications in packaging, electronics, and automotive industries. Its contribution to adhesion strength and durability elevates adhesive performance. Plastics Manufacturing: Copolymerization with other monomers produces specialty plastics for optical lenses, optical disks, and plastic films. These materials leverage its clarity and mechanical stability, making them suitable for optical and packaging applications. It is also used in transparent plastics for products like automotive lampshades. Textile and Fiber Treatment: It is employed in fabric coating and finishing, improving fabrics’ waterproofness, stain resistance, and abrasion resistance while enhancing feel and appearance—beneficial for garments and home textiles. It also has applications in fibers and fabric treatment agents. Specialty Materials: It contributes to the production of insulation materials, cladding materials, and dispersants. Additionally, it serves as a raw material in ink formulations, pharmaceutical intermediates, and surfactants, supporting electronics, chemical, and pharmaceutical industries.
Related Products	Customers interested in t-Butyl methacrylate often seek other acrylate and methacrylate monomers for complementary or alternative applications in polymer synthesis and specialty formulations. Key related products include methyl methacrylate (MMA), a foundational monomer for transparent plastics and coatings; butyl acrylate (BA), valued for improving flexibility in adhesives and paints; ethyl methacrylate (EMA), used in dental materials and impact-resistant plastics; and isobornyl methacrylate (IBOMA), known for enhancing weatherability and chemical resistance in coatings.
