A Breakthrough! In-House Two-Component System Achieves a New Milestone in High-Film-Thickness, High-Gloss, Eco-Friendly Coatings

Breaking a technical barrier that has plagued the industry for over a decade: The challenge of achieving high film thickness and high gloss with waterborne two-component emulsion coatings has finally been overcome today!

Those deeply engaged in the field of two-component emulsion coatings know this well: achieving high gloss with low film thickness has long been commonplace. However, once the construction shifts to high film thickness, persistent issues such as cracking, alligatoring, bubbles, and pinholes emerge one after another, becoming a technical dead end that has haunted the industry for years, seemingly without a solution.

Shanghai Handai Chemical has broken through this bottleneck with its hardcore in-house R&D, delivering a groundbreaking technological innovation! The core combination features a high-solid, low-viscosity epoxy emulsion HDE3264 paired with a specialized emulsion-type curing agent HDH6882. This dual-component synergy redefines the coating's performance system.

It combines environmental friendliness with exceptional performance: adhering to a zero-VOC formula with no pungent odors, it fully complies with stringent environmental standards, ensuring green, safe, and worry-free application.

The measured performance is outstanding in every aspect: ultimate fluidity achieves a genuine self-leveling effect, resulting in a flawlessly smooth and polished finish; the 60° gloss measures an impressive 80-90, delivering a high-gloss texture that is second to none. It stably accommodates ultra-thick coating applications of up to 1000μm, with no cracking, bubbling, or pinholes in thick coatings, completely eliminating the risks associated with thick-coat applications. Additionally, it extends the product's pot life, addressing the common issues of easy failure and short working windows in two-component emulsion coatings, significantly reducing on-site construction challenges and ensuring a more hassle-free application.

This achievement is the result of three years of dedicated R&D, myriad formulation iterations, and countless trials and errors. From the technical dilemma of thick-film cracking to the perfect realization of defect-free film formation, we have conquered every defect with craftsmanship and delivered on every promise of quality through innovation.

Rooted locally, empowered by science and technology! Shanghai Handai Chemical stays true to its domestic brand mission, using tangible technological breakthroughs to support the high-quality development of China’s green and environmental protection industries, writing a new chapter in the innovation of the national chemical sector.
