Product Definition

Imprimación intermedia epoxi de mica de hierro（Epoxy MIO Intermediate），Chinese standard number HG/T 3668-2020. It is a two-component (2K) room-temperature crosslinking anticorrosive primer using epoxy resin (bisphenol-A type, CAS 25068-38-6) and polyamide curing agent (CAS 68410-23-1) as the film-forming material, ultrafine spherical zinc powder (CAS 7440-66-6, particle size 3-8μm, dry film mass fraction ≥70%) as the anticorrosive pigment, and xylene/n-butanol as the solvent system.

Corrosion protection mechanism:High-content zinc powder particles in the coating form continuous conductive pathways between themselves and with the steel substrate. Since the standard electrode potential of zinc (-0.76V vs SHE) is lower than that of iron (-0.44V), zinc acts as the anode in corrosion microcells and preferentially undergoes oxidation (Zn → Zn²⁺ + 2e⁻). The released electrons flow through the conductive network to the steel surface, cathodically polarizing the steel below its immune potential—this is known as "sacrificial anode cathodic protection." Meanwhile, the corrosion products of zinc (ZnO, Zn(OH)₂, basic zinc carbonate, etc.) gradually fill the coating pores, forming a dense secondary barrier layer—the "corrosion product self-healing effect."

Key performance data:

  • The dry film zinc powder content is ≥70% (compliant with HG/T 3668-2020 Category 2).
  • Contenido de sólidos en volumen ≥60 % (ISO 3233:1998)
  • Adherencia por método de tracción ≥ 6 MPa (ISO 4624:2016, con dolly de 20 mm de diámetro para la prueba).
  • Resistencia a la niebla salina neutra (NSS) de una sola capa ≥ 400 h (ISO 9227:2022, ancho de corrosión en la línea de rayado ≤ 2 mm).
  • Sistema combinado (imprimación epoxi rica en zinc 80 μm + capa intermedia epoxi de mica de hierro 150 μm + pintura de poliuretano 80 μm) Resistencia a NSS ≥ 1000 h.
  • Mixed application period: 4-8 hours (23°C, main agent: curing agent = 10:1 w/w)

Applicable substrates and limitations:Applicable to carbon steel, low-alloy steel, and cast iron substrates blasted to Sa2.5 (ISO 8501-1:2007). Not recommended for direct application on galvanized steel (the passivation film on the zinc surface will block the conductive path—sweep blasting pretreatment or an epoxy primer transition layer is advised), stainless steel (the surface passivation film must be removed first), or aluminum alloy (risk of galvanic corrosion—the potential difference between zinc and aluminum is too large). Application temperature limits: standard type 5–40°C (below 5°C, the epoxy-amine crosslinking reaction rate is extremely low, resulting in incomplete coating curing).

Posición en la industria y aplicaciones:Imprimación intermedia epoxi de mica de hierrois one of the most widely used primer types in global heavy-duty anticorrosive coating systems (ISO 12944-5:2019 systems A2.08/A3.08/A4.08, etc.), forming a classic triple-protection system with epoxy MIO intermediate coat and PU/fluorocarbon/polysiloxane topcoat. Typical applications include: Akashi Kaikyo Bridge Japan (opened 1998, 100-year design life), Hong Kong-Zhuhai-Macao Bridge (opened 2018, 500,000m² steel box girders), North Sea offshore oil platforms (NORSOK M-501 system certification), etc. According to Grand View Research, the global zinc-rich primer market was approximately USD 2.8 billion in 2023, with Asia-Pacific accounting for 48% share.

Cathodic protection sacrificial anode principle

1. Mecanismo de protección catódica (ánodo de sacrificio)

CoatingDry Film含≥70%锌粉形成连续导电网络。锌的Standard电极电位（-0.76V）低于铁（-0.44V），腐蚀发生时锌优先氧化（Zn→Zn²⁺+2e⁻），Releasing electrons to cathodically polarize steel to its immune potential——即使Coating有3-5mm破损，The surrounding zinc powder can still provide continuous electrochemical protection for exposed steel.，This makes the anti-corrosion performance of epoxy micaceous iron oxide intermediate paint far superior to that of ordinary anti-rust primers relying solely on physical shielding.。

Salt spray resistance test 1000 hours

Airless Spray Application

4. Amplia adaptabilidad de aplicación

Supports airless spray (nozzle 0.43–0.53 mm, 15–25 MPa), air spray, and brush/roller application (for small-area touch-ups). Single-pass dry film thickness: 60–80 μm. Mixing ratio: 10:1 (w/w). Pot life: 4–8 h (23°C). Wide temperature range for application (5–40°C); low-temperature formulation can be applied down to –5°C. Continuous stirring is required during spraying to prevent zinc powder sedimentation—use of a pressure pot with a pneumatic agitator is recommended to ensure coating uniformity.

Shop primer welding application

5. Imprimación de taller soldable (Shop Primer)

Specialized formulation (dry film 15-25μm) can be used as a shop primer—after application in the steel structure prefabrication plant, the steel remains suitable for welding and cutting. Welding fumes comply with occupational exposure limits (GBZ 2.1-2019), and the pass rate of X-ray inspection of welds is not affected. Suitable for automated spray painting on steel structure production lines—parts can be handled and stacked within 3-5 minutes after spraying. Note: Only the specialized shop primer formulation is weldable—the standard type with a dry film thickness of 60-80μm is not suitable for welding.

FAQ

常见问题

The anti-corrosion of epoxy micaceous iron oxide intermediate paint is based on the principle of electrochemical cathodic protection：Coating中高含量（≥70%）的锌粉颗粒之间形成导电通路，且与钢材基体导通。由于锌的Standard电极电位（-0.76V）比铁（-0.44V）更负，腐蚀发生时锌优先氧化：Zn→Zn²⁺+2e⁻。Released electrons flow toward the steel surface through the conductive network，使其阴极极化——电位降至-0.85V（vs Cu/CuSO₄）以下即可实现有效保护。如果锌粉含量不足（<60%），锌粉颗粒被环氧树脂绝缘包裹无法形成连续导电通路——Cathodic protection失效——Coating仅剩物理屏蔽功能，Anticorrosive寿命大幅缩短。这就是HG/T 3668Standard严格要求锌粉含量的原因：第1类≥80%（高Anticorrosive），第2类≥70%（Standard重Anticorrosive），第3类≥60%（一般Anticorrosive）。
No se puede usar soloTres Razones：(1)Imprimación intermedia epoxi de mica de hierro单层暴露在酸性（酸雨pH<5.6）或碱性（Concrete渗出碱液）Environment中，锌粉会被Quick化学消耗（反应速率较中性Environment快3-10倍），丧失Cathodic protection能力。Imprimación intermedia epoxi de mica de hierro（MIO片状填料层叠排列形成"迷宫效应"）Provides物理屏蔽层——保护锌粉不过早消耗。(2)环氧树脂含芳香醚键——紫外光（290-400nm）照射下3-6个月即开始光氧化降解——粉化/变色/失光。聚氨酯/Fluorocarbon Topcoat（含UV吸收剂和HALS光稳定剂）ProvidesWeather-Resistant保护。(3)配套System总DFT更厚（≥280μm）——Anticorrosive等级更高。ISO 12944-5推荐的重Anticorrosive配套：Imprimación intermedia epoxi de mica de hierro60-80μm + Imprimación intermedia epoxi de mica de hierro100-150μm + 聚氨酯Topcoat50-80μm×2。
According to HG/T 3668-2020, three types of zinc content are selected: Type 1 (≥80%) — suitable for C5/CX extremely corrosive environments (offshore splash zones, tidal zones, chemical plant acid mist areas) or major projects with a design life >25 years. It offers the highest cathodic protection efficiency, but excessive zinc powder increases internal stress and reduces flexibility (flexibility ≥3mm vs. Type 2's ≥2mm), and has the highest unit price. Type 2 (≥70%) — a general heavy-duty anti-corrosion primer suitable for C4-C5 environments (coastal industrial areas, sea-crossing bridges, petrochemical storage tanks), offering the best cost-performance ratio — an optimal balance between anti-corrosion performance and mechanical properties. Recommended for most industrial projects. Type 3 (≥60%) — suitable for C3-C4 environments (urban atmosphere, ordinary industrial plants) with general anti-corrosion requirements. Can be selected if the budget is limited and the environmental corrosion level is low. Selection suggestion: When in doubt, choose Type 2 (70%) — the safest universal option.
Zinc powder has a high density (7.14 g/cm³) and tends to settle easily in low-viscosity epoxy resin solutions. Solutions: (1) After opening the container, thoroughly stir with an electric/pneumatic stirrer for ≥5 minutes—completely lift the zinc powder from the bottom until no sediment remains. (2) After adding the hardener, continue stirring for 3-5 minutes until the mixture has a uniform color. (3) Maintain continuous low-speed stirring throughout the application process—a pressure tank with a pneumatic stirrer (rotation speed 30-60 rpm) is recommended to prevent zinc powder from re-settling during spraying, which could cause inconsistent zinc content between the initial and final spray. (4) Paint that has settled and hardened into lumps—do not forcibly stir for use (the zinc powder has separated from the resin and may form lumps, leading to pinholes, uneven zinc distribution, and reduced adhesion after spraying). Paint that has exceeded its mixed pot life and shows gelation—must be discarded. It is recommended to prepare the paint as needed (estimate usage within 2 hours), in small, multiple batches.
Imprimación intermedia epoxi de mica de hierroWhen exposed to air, surface zinc powder reacts with CO₂ and H₂O to form basic zinc carbonate ("white rust"). After 7 days (23°C, 50%RH), the following treatment is required: (1) Visual inspection — white powdery zinc salts must be removed by sweep blasting using low pressure (0.2-0.3MPa) non-metallic abrasive (garnet/alumina) to remove the zinc salt layer and create 20-30μm roughness. (2) For coatings within 6 months without visible zinc salts — light sanding (180-240 grit hand sanding) is sufficient. (3) If the coating shows extensive chalking/rusting/peeling — complete blast removal and reapplication is required. Prevention: Complete intermediate coat application within the minimum recoat interval (8-24h) when the primer surface still has active amine groups (incompletely crosslinked), achieving optimal intercoat adhesion without sanding.
Diferencia clave: diferente formador de película.Epoxy zinc-rich — organic epoxy resin + polyamide curing agent; inorganic zinc-rich — inorganic ethyl silicate/lithium silicate hydrolysis condensation. Selection comparison: (1) Anti-corrosion performance: Inorganic zinc-rich primer (zinc content ≥85%) offers higher cathodic protection efficiency, certified under NORSOK M-501 and SSPC Paint 20 Type I (inorganic) — Type II (organic). Both can achieve equivalent anti-corrosion grades, but inorganic is slightly superior. (2) Application tolerance: Epoxy zinc-rich >> inorganic zinc-rich. Epoxy can be applied at 5–40°C/RH<85%宽条件Application；无机对RH要求苛刻——RH需50-90%（硅酸乙酯水解需要水分），低温（<5°C）和低湿（<40%）均无法正常Curing——Application窗口窄。(3)层间Adhesion：环氧富锌+Imprimación intermedia epoxi de mica de hierro的层间结合力（>5 MPa) is superior to inorganic zinc-rich + epoxy intermediate paint (possibly due to the porous nature of the inorganic coating increasing the contact area, but also potentially leading to insufficient adhesion due to surface chalking—requiring sweep blasting). (4) Cost: Epoxy zinc-rich is approximately 0.7–0.8 times the cost of inorganic zinc-rich. Selection recommendations: For conventional heavy-duty anti-corrosion projects, choose epoxy zinc-rich (easy application + high cost-effectiveness); for extreme marine environments (splash zone/tidal zone) or top-tier projects with a design life of ≥30 years—choose inorganic zinc-rich + sealer + epoxy intermediate coat + polysiloxane topcoat.
