In organosilicon intermediate synthesis and polymer modification, traditional silane coupling agents have single function and insufficient epoxy reactivity; ordinary silicones have poor compatibility with organic resins, failing stable chemical bonding; water-based coating additives lack water resistance and adhesion; epoxy-modified silicone oil synthesis is complex with high raw material purity demands. For specifications demanding "epoxy-functionalized, silane coupling modification, organosilicon intermediate synthesis, water-based coating additive, epoxy-modified silicone oil", a strictly controlled epoxy silane places coupling activity and synthesis versatility at one silane node. Addressing this, Anhui IOTA Silicone Oil Co., Ltd. launches IOTA 5562 (3-Glycidoxypropyl)methyldiethoxysilane (also named Diethoxy(3-glycidyloxypropyl)methylsilane; [3-(2,3-Epoxypropoxy)propyl]diethoxymethylsilane). Molecular formula C₁₁H₂₄O₄Si, MW 248.39, CAS 2897-60-1, EINECS 220-780-8. Boiling point 122-126℃(5mmHg), refractive index 1.431, flash point 110℃, density 0.978. Applications: used in synthesis of organosilicon intermediates and polymer compounds, silane coupling agent for organic resin modification; production of water-based paint additives; production of epoxy-modified silicone oil. Packaging: 25kg, 200kg plastic drum or closed steel drum, other specs by reservation. Brand IOTA. System Positioning: Epoxy Silane Among Silane Coupling Agent Families Within silane coupling agent families, IOTA 5562 is an epoxy alkoxy silane, distinct from amino silanes (react with epoxy causing failure), mercapto silanes (need light or radical initiation), vinyl silanes (need platinum catalyst), pure alkyl ethoxy silanes (no functional group, no coupling). IOTA 5562 uses terminal epoxy for chemical reactivity with organic resins, diethoxy methyl silyl for hydrolysis condensation, positioning as a multi-functional epoxy silane for "organosilicon intermediate synthesis + organic resin modification + water-based coating additives + epoxy-modified silicone oil", rather than single-use coupling agents. Molecular Architecture: C₁₁H₂₄O₄Si Epoxy Propyl Methyl Silane + BP 122-126℃ + FP 110℃ + D 0.978 IOTA 5562 core is C₁₁H₂₄O₄Si structure containing epoxy (glycidyl ether), propyl spacer, methyl diethoxy silyl. Epoxy group provides ring-opening reactivity with amines, hydroxyls, carboxyls for chemical bonding; diethoxy methyl silyl hydrolyzes to silanol for condensation with inorganic substrates; density 0.978, RI 1.431, flash point 110℃ balance safety and handling; boiling point 122-126℃(5mmHg) eases purification; MW 248.39 ensures moderate reaction equivalent. Performance Leap: From "Single Function, Poor Compatibility" to "Epoxy Silane Bridge, Coupling Modification" With IOTA 5562, organosilicon synthesis and resin modification improve jointly: coupling activity—epoxy reacts with resins forming stable bonds, enhancing adhesion and compatibility; synthesis versatility—widely used in organosilicon intermediates and polymer synthesis; water-based coatings—as additive improves water resistance and adhesion; epoxy silicone oil—raw material for epoxy-modified silicone oil; safety—flash point 110℃ enhances operational safety. Application Penetration: From Organosilicon Intermediates to Resin Modification and Water-Based Coatings IOTA 5562 covers three core scenarios. Organosilicon intermediate synthesis—emphasizing reactivity and purity; trial per synthesis route. Organic resin modification—silane coupling agent modifying organic resins, emphasizing coupling effect; trial per resin system. Coatings and silicone oil—water-based coating additives, epoxy-modified silicone oil production; trial per formulation. ⚠️ Taboo: store cool dry, avoid strong acids/bases causing hydrolysis; seal packaging to prevent moisture; ventilate during operation. IOTA Technical Guide: Plastic/Closed Steel Drum, Custom Order, Sealed Moisture-Proof Storage IOTA 5562 is a liquid in 25kg/200kg plastic drum or closed steel drum, other specs by reservation. Pre-hydrolyze or mix directly with resin before use. Store sealed in cool dry place, prevent moisture absorption. Industry Insight: Epoxy silane selection is not the more epoxy the better, but using molecular structure for reactivity, hydrolysis rate for coupling efficiency, purity for synthesis yield, flash point for operational safety. For organosilicon synthesis engineers, IOTA 5562 uses one epoxy diethoxy methyl silane across intermediate synthesis, resin modification, water-based coatings and epoxy silicone oil, taking epoxy silane bridge and coupling modification as batch-checkable anchors, securing reactivity and versatility simultaneously.
