Direct from our Ningxiang advanced atomization and fine classification plant. Optimized for extreme packing density, thermal percolation, and flawless optical consistency.
How metallurgical purity, controlled solvent carriers, and strict lamellar morphology dictate performance across high-stress global manufacturing value chains.
Mepco-type aluminium pastes depend upon micro-mechanical wet ball milling to transform atomized spherical aluminium into high-aspect-ratio cornflake or silver dollar flakes. Maintaining surface uniformity without flake micro-fractures ensures continuous electrical and optical properties across coating and composite layers.
Unlike raw dry powders that carry severe UN1396 dust-explosion hazards, paste formulations stabilize aluminium pigments in hydrocarbon spirits (mineral spirit, solvent naphtha, or diethylene glycol). This prevents micro-oxidation and delivers consistent shear rheology during industrial automated pumping and application.
The transition toward electrification has driven demand for non-oxidized, high-purity aluminium suspensions. When paired with silane and titanate surface modifiers, these formulations achieve up to 88 wt% solids loading in epoxy or silicone matrices without exceeding viscosity limits in automated dispensing valves.

Situated within the Ningxiang National Economic and Technological Development Zone, our production infrastructure benefits from direct proximity to domestic chemical clusters and integrated upstream aluminium smelting operations. This location minimizes raw-material transit times, protects against geopolitical shipping disruption, and keeps molten metal processing energy-efficient.
From induction melting under protective inert atmospheres through high-pressure gas atomization and ultrasonic sifting, our systems prevent uncontrolled contact with ambient moisture. This process discipline preserves active aluminium content (typically >99.5% active metal), ensuring stable shelf life and uniform gas release in downstream applications.
Formulations designed to perform reliably across demanding automotive, aerospace, renewable energy, and construction environments.
Non-leafing silver dollar pastes oriented parallel to the substrate deliver high flip-flop (two-tone) color shift with zero surface micro-roughness under clearcoats.
Sub-micron paste systems engineered for screen printing on crystalline silicon solar wafers, creating an efficient back-surface field (Al-BSF) with uniform ohmic contact.
Specialized water-dispersible leafing aluminium pastes that provide controlled hydrogen gas expansion during the pre-curing stage of lightweight AAC building blocks.
High-solids spherical and passivated matrix pastes used in gap fillers and potting resins, maintaining stable thermal paths under severe thermal cycling.
A rigorous audit structure built to support Fortune 500 chemical groups, tier-1 powder metallurgy producers, and advanced materials engineering teams.
Every shipment is verified using laser diffraction (Malvern Mastersizer) to confirm D10, D50, and D90 parameters. Flake thickness is measured by water-coverage surface area testing to ensure batch-to-batch consistency and predictable leafing value.
We tailor carrier systems to fit customer production chemistries: white spirit for solvent coatings, high-flash dearomatized fluids for indoor production, and customized glycol carriers for waterborne systems that avoid VOC spikes.
All product lines are supported by REACH registrations, RoHS compliance statements, complete SDS documentation, and certified UN-standard steel drums that keep paste chemically stable and safe during intercontinental ocean transport.
Clear, direct guidance from our materials engineers on custom formulations, shelf stability, and international logistics.
Standard aluminium powder is dry atomized metal (spherical, nodular, or irregular) commonly used in additive manufacturing, powder metallurgy, or thermite reactions. Mepco-style aluminium paste consists of precision-milled lamellar flakes suspended in a hydrocarbon or solvent carrier. This delivers mirror-like metallic orientation, prevents dry dust explosions, and streamlines incorporation into paint and liquid resin formulations.
Unprotected aluminium flakes react vigorously with water to generate hydrogen gas. For waterborne coatings, we apply multi-layer chemical passivation (using organosilane or inorganic phosphate treatments). This creates a barrier layer that resists moisture attack, preventing gassing while preserving high gloss and metallic reflectance.
For standard catalog formulations, typical lead time is 7–14 days. Custom particle size engineering, tailored carrier solvent switches, or specialized silane surface coatings generally require 2–3 weeks. Our flexible manufacturing setup accommodates trial orders from 500 kg up to continuous maritime container volumes (20-ft FCL / 10 to 14 metric tonnes).
We operate under certified ISO 9001:2015 and ISO 14001:2015 processes, enhanced by the quality governance of Toyo Aluminium K.K. Every batch is evaluated for particle size distribution, non-volatile matter, water coverage, and optical properties (including lightness L* and flop index). Detailed Certificates of Analysis (COA) accompany every shipment for full traceability.
