Innovative efforts & outcomes
CORE TECHNOLOGIES
Ecosil’s core technologies provide a strong foundation for the development of high-performance products
SILSBOND Pretreatment
- Patented hybrid pretreatment combining organic and inorganic materials to enhance paint adhesion and prolonged lifespan of painted metal parts
- A thin film at the nanoscale, ranging from 20 to 50 nm in thickness, can be formed onto a metal surface through either ambient immersion or spraying methods
- The SILSBOND pretreatment process is brief and operates at ambient conditions, effectively reduces flash rust, and does not require waste management
- Products sold across various industries and applications in the US and China
- military TT-C-490 specification approval
Silane-based Passivation
- An organofunctional silane-based, Cr-free passivation film (0.5–1.5 μm thick) for corrosion protection of galvanized steel coils
- Can be used in both continuous and batch galvanized steel production lines
-Offers strong wet storage stain protection for various galvanized steel coils
-Additional advantageous features are resistance to fingerprints, humidity, and solvents or acids/bases, as well as surface conductivity and excellent formability that does not require metal forming oil
White Paper: Silane-based, chrome-free metal passivation technology
Cr3 Passivation
-Eco-friendly, cost-effective trivalent chromium (Cr3)-based conversion coating, free from hexavalent chromium (Cr6)
- It quickly reacts with the zinc surface to form a conversion coating, resulting in a coating weight of 30–50 mg/m²
- Can be used in both continuous and batch galvanized steel production lines
- Provides excellent corrosion resistance for various galvanized steel coils
- Additional desirable properties include humidity resistance, surface conductivity and good formability
White Paper: Low-cost, trivalent chromium conversion coating technology
Cr-free, Thin Organic Coating
- Advanced chromium-free thin organic coatings (TOCs), with a thickness ranging from 0.8 to 2.0 µm, are engineered to provide corrosion protection for high aluminum-content alloy coatings, such as Galvalume® (55% Al-Zn alloy-coated steel)
- Can be customized in various colors to accommodate customers' decorative preferences
- Offers excellent corrosion protection to Galvalume
- Other desirable properties: anti-fingerprint, excellent adhesion to paints/adhesives
