Similar programmes spread to Canada and Japan, ensuring long-term support for sustainable chemistry platforms across the waterborne epoxy resin market.

Performance Gap vs. Solvent-Borne in Heavy-Duty Anti-Corrosion

Waterborne epoxies still lag behind solvent-borne rivals in the barrier properties required by ships and offshore platforms. Moisture presence during film formation can create micro-porosity that lowers impedance values. Comparative studies show that solvent-borne coatings maintain resistance above 10^9 Ω after extended salt-spray exposure, whereas waterborne equivalents plateau at a value nearer 10^8 Ω, necessitating thicker builds or more frequent maintenance. International Marine’s low-VOC product lines have helped mitigate part of this gap, yet applicators remain cautious about life-cycle costs, constraining uptake in the waterborne epoxy resin market.

Price Volatility and Nano-Silica Solvent-Free PU Top-Coats

Bisphenol-A and epichlorohydrin prices fluctuate with crude-oil shifts and downstream supply outages, pressuring formulators’ margins. At the same time, nano-silica-filled solvent-free polyurethanes are positioning themselves as direct substitutes by offering similar abrasion resistance without water sensitivity. UV-curable epoxy-modified silicone hybrids now deliver 95% light transmission and 5H hardness, narrowing the performance gap while retaining near-zero VOC^{[3]MDPI, “UV-Cured Epoxy-Modified Silicone Coatings With High Transparency,” mdpi.com} . Budget-constrained buyers may favour these alternatives, limiting near-term penetration of premium waterborne technologies in certain regions of the waterborne epoxy resin market.
