Engineering Superiority: The Tortuous Path

PRECISE DIFFUSION BARRIERSTEEL SUBSTRATEBARRIER PHYSICSGlass FlakesHazard PathImpermeable alignmentforces detour.

Unlike traditional spherical or irregular fillers, our precision-cut flakes orient parallel to the substrate. This creates a dense barrier of overlapping plates, forcing moisture and ions to travel a tortuous path up to 10× longer than the coating thickness.

Permeability Control

Dramatic reduction in water vapor transmission (MVT) through coating matrix.

Dimensional Stability

Minimizes shrinkage stress during curing and thermal cycling.

Chemical Resistance

Inert C-Glass provides a robust shield against aggressive acids and alkalis.

FAQ

The letters indicate surface treatment: 'N' means non-surface treatment, and 'E' means surface-treated by silane coupling agents for better compatibility with epoxy resin. We recommend C-90E for roller or trowel applications.

Typical MOQ is 1,000 KGS (1 ton). Products are supplied in moisture-proof paper bags of 20 or 25 KGS net weight, palletized in boxes (~1.24 × 1.13 × 1.35 m) wrapped in polythene.

We offer FOB (e.g., Tianjin), CIF (e.g., Rotterdam or PUSAN), and DAP. Pricing varies by volume, grade, and market conditions. Contact our team for a formal quotation.

Samples are provided free of charge; customers cover freight, which may be discounted on the first official order. Freight can be paid via wire transfer or Stripe.

International orders typically ship within 2–4 weeks depending on destination and shipping method.

Currently we ship directly to customers worldwide and do not have a European distributor network.

Initial orders begin on Advance Payment basis, progressing to Payment against Bill of Lading once quality is approved.

TDS, GHS MSDS, and COA documents are available on request and often provided with sample shipments. Visit our website for particle size distribution data.
