Handai Chemical's waterborne epoxy zinc-rich primer solution HDE8513 + HDH6119B

在工业防护涂料领域，寻求一款兼具卓越性能、经济高效与环保特性的产品始终是核心诉求。瀚岱化学凭借深厚技术积淀与创新精神，匠心独运地推出水性环氧富锌底漆解决方案 ——HDE8513 + HDH6119B，宛如一颗璀璨星辰，以七大显著优势为金属表面防护构筑起坚不可摧的防线。

In the field of industrial protection coatings, it has always been the core demand to seek a product that combines excellent performance, cost-effectiveness and environmental friendliness. Relying on its profound technological accumulation and innovative spirit, Handai Chemical has ingeniously launched the waterborne epoxy zinc-rich primer solution - HDE8513 + HDH6119B, just like a brilliant star, building an impregnable defense line for the protection of metal surfaces with seven remarkable advantages.

一、革新工艺，超长盐雾防护

1. Innovative Process for Ultra-Long Salt Spray Protection

传统富锌底漆锌粉分散不均常致防护漏洞，而 HDE8513 + HDH6119B 独辟蹊径，于固化剂中精准研磨锌粉，实现微观层面均匀分布。锌粉颗粒紧密贴合金属基材，形成连续致密电化学保护屏障，有效阻滞氯离子、水汽侵蚀路径。经严苛测试，盐雾防护时长飙升至 2000 小时，远超同类竞品，无论是海滨设施饱经海风盐雾侵袭，还是化工装置直面酸碱雾气腐蚀，皆能长效护航金属结构，大幅削减维护频次与成本。

Traditional zinc-rich primers often suffer from uneven zinc powder dispersion, leading to protection loopholes. In contrast, HDE8513 + HDH6119B takes a unique approach by precisely grinding the zinc powder in the curing agent, achieving a uniform distribution at the microscopic level. The zinc powder particles closely adhere to the metal substrate, forming a continuous and dense electrochemical protection barrier that effectively blocks the intrusion paths of chloride ions and water vapor. After rigorous testing, the salt spray protection duration soars to 2000 hours, far exceeding similar competing products. Whether it's coastal facilities battered by sea breeze and salt spray or chemical installations facing acid-base fog corrosion, it can provide long-term protection for metal structures, significantly reducing maintenance frequencies and costs.

二、精简配方，降本增效典范

2. Streamlined Formula, a Model of Cost Reduction and Efficiency Enhancement

摒弃繁琐，方显高效。此方案无需润湿分散剂，凭借固化剂与乳液精妙协同，自发促使锌粉均匀分散悬浮，简化配方架构。原材料精简直接拉低采购成本，生产流程亦随之缩短，人力、能耗开支锐减；且乳液部分可直接加水稀释，免除有机溶剂购置、储存与回收环节，从多维度为企业 “瘦身减负”，让优质防护不再意味着高昂代价。

Simplicity leads to efficiency. This solution dispenses with the need for wetting and dispersing agents. Through the exquisite coordination between the curing agent and the emulsion, it spontaneously promotes the even dispersion and suspension of zinc powder, simplifying the formula structure. The reduction in raw materials directly cuts procurement costs, and the production process is shortened accordingly, with significant reductions in labor and energy consumption expenditures. Moreover, the emulsion part can be directly diluted with water, eliminating the need for the purchase, storage, and recovery of organic solvents, "slimming down" enterprises from multiple dimensions and making high-quality protection no longer synonymous with high costs.

三、灵活调控，适配多元需求

3. Flexible Adjustment to Meet Diverse Needs

市场多变，需求各异。HDE8513 + HDH6119B 具备卓越可塑性，轻松实现不同锌粉含量产品定制。从轻度腐蚀防护场景适度锌粉配比，到重度侵蚀工况下高锌粉强化抵御，皆能精准调配，如同为不同金属防护 “病症” 开具专属 “良方”；同时，可依施工工艺灵活调整粘度，完美兼顾刷涂、喷涂、辊涂要求，于各类工业项目中无缝适配，游刃有余。

The market is dynamic, and demands vary. HDE8513 + HDH6119B exhibits outstanding plasticity, allowing for easy customization of products with different zinc powder contents. From a moderate zinc powder ratio for mild corrosion protection scenarios to a high zinc powder reinforcement for severe erosion conditions, it can be precisely formulated, much like prescribing specific "prescriptions" for different metal protection "ailments". At the same time, the viscosity can be flexibly adjusted according to the construction process, perfectly accommodating brushing, spraying, and rolling requirements, seamlessly adapting to various industrial projects with ease.

四、卓越流变，施工无忧保障

4. Excellent Rheological Properties, Ensuring Hassle-Free Construction

施工顺畅是项目高效推进关键。该底漆触变性强，静止时呈高粘度凝胶态，有效防止锌粉沉降，确保储存稳定性，漆料久置不分层、不结块；施工瞬间，经机械剪切力作用，粘度骤降，流动性激增，均匀覆盖金属表面，配合优秀抗流挂性能，即便复杂构件、垂直立面施工，亦无流坠、滴淌之忧，一次成膜平整光滑，助力施工团队争分夺秒，保障项目如期交付。

Smooth construction is crucial for the efficient progress of projects. This primer has strong thixotropy. When at rest, it presents a high-viscosity gel state, effectively preventing zinc powder sedimentation and ensuring storage stability. The paint remains well-mixed without stratification or caking over time. During construction, under the action of mechanical shear force, the viscosity drops rapidly, and the fluidity surges, evenly covering the metal surface. Coupled with excellent anti-sagging properties, even during the construction of complex components and vertical facades, there is no worry of dripping or sagging. The film formed in one pass is flat and smooth, helping construction teams save every minute and ensuring project delivery on schedule.

展望未来，瀚岱化学研发团队将秉持精益求精理念，深研 HDE8513 + HDH6119B 组合潜力，进一步提升性能天花板；紧密携手上下游伙伴，引领水性环氧富锌底漆技术革新潮流，用创新科技赋能全球工业，成为金属防护领域矢志不渝的领航者，让经得住岁月与腐蚀磨砺的防护涂层，守护世界工业根基。

Looking ahead, the R & D team of Handai Chemical will adhere to the concept of continuous improvement, delving deeper into the potential of the HDE8513 + HDH6119B combination to further raise the performance bar. Working closely with upstream and downstream partners, they will lead the trend of technological innovation in waterborne epoxy zinc-rich primers, empowering the global industry with innovative technology and becoming an unwavering leader in the field of metal protection. Let the protective coatings that withstand the tests of time and corrosion safeguard the foundation of the world's industry.
