Handai Chemical's excellent boiling water resistance test solution HDE8118 + HDH6815.

在涂层性能严苛考验的竞技场上，瀚岱化学凭借深厚技术沉淀与创新实力，隆重推出耐水煮测试方案 ——HDE8118 + HDH6815，这一组合犹如一对默契无间的 “黄金搭档”，为涂层在极端湿热环境下的稳定性立下卓越标杆，全方位护航金属制品长效防护与美观需求。

In the arena of stringent tests for coating performance, Handai Chemical, relying on its profound technological accumulation and innovative capabilities, has grandly introduced the boiling water resistance test solution - HDE8118 + HDH6815. This combination is like a seamless "golden duo", setting an outstanding benchmark for the stability of coatings in extremely humid and hot environments and comprehensively safeguarding the long-term protection and aesthetic needs of metal products.

精准选材，夯实品质根基

Precise Material Selection, Consolidating the Quality Foundation

方案基石之一的 HDE8118，作为一款精心雕琢的白色环氧分散体，以 53% 的高固含量脱颖而出。高固含特性意味着更少挥发成分，在成膜过程中能高效凝聚更多有效物质，为漆膜致密性与连贯性筑牢根基；其细腻均匀的分散态，确保各成分均匀分布，避免团聚缺陷，如同精密编织的分子网格，赋予涂层初始强度与韧性，是后续卓越耐水煮性能的关键 “先手棋”。

HDE8118, one of the cornerstones of the solution, stands out as a meticulously crafted white epoxy dispersion with a high solid content of 53%. The high solid content implies fewer volatile components, enabling the efficient aggregation of more effective substances during the film-forming process and laying a solid foundation for the compactness and coherence of the paint film. Its fine and uniform dispersion state ensures the even distribution of each component, avoiding agglomeration defects. It is like a precisely woven molecular grid, endowing the coating with initial strength and toughness, which is a crucial "opening move" for subsequent excellent boiling water resistance performance.

与之珠联璧合的 HDH6815，身为白色环氧固化剂，50% 固含量绝非偶然之数。这一精准配比的固含量，恰如其分地与 HDE8118 呼应，在交联固化反应中实现完美 “会师”。它能深度嵌入 HDE8118 分子链间，催化化学键形成，编织出三维立体网状结构，大幅提升涂层整体刚性、耐化学性及耐热性，如同为漆膜注入坚韧 “骨架”，使其在水煮高温下稳如泰山。

HDH6815, the white epoxy curing agent that pairs perfectly with it, has a solid content of 50% for a definite reason. This precisely proportioned solid content corresponds precisely to HDE8118, achieving a perfect "rendezvous" in the crosslinking and curing reactions. It can deeply embed itself between the molecular chains of HDE8118, catalyzing the formation of chemical bonds and weaving a three-dimensional network structure, significantly enhancing the overall rigidity, chemical resistance, and heat resistance of the coating. It is like injecting a tough "skeleton" into the paint film, making it as stable as a mountain under high-temperature boiling water.

严苛工艺，雕琢极致性能

Stringent Processes, Carving Out Extreme Performance

制备环节，将 HDE8118 与 HDH6815 依精确比例均匀混合，经专业高速分散设备搅匀，确保分子级别的充分交融，激活二者化学反应潜能，让每一滴漆料都蕴含均匀稳定的性能 “密码”。随后，采用先进喷涂设备，精准控制气压、流量，将漆料均匀雾化，细密铺陈于冲砂钢板之上，严格把控膜厚在 60 - 80μm 黄金区间。冲砂钢板经预处理，表面微糙，为漆料提供理想锚固点，增强附着力；精准膜厚则平衡涂层防护性与经济性，太厚易龟裂，太薄难抵御侵蚀，此区间确保涂层在水煮时应力均匀分布，抵御水汽渗透。

During the preparation stage, HDE8118 and HDH6815 are evenly mixed in an exact proportion and stirred thoroughly by professional high-speed dispersion equipment to ensure full integration at the molecular level, activating the chemical reaction potential of the two. This makes every drop of paint contain a uniform and stable performance "code". Subsequently, advanced spraying equipment is used to precisely control air pressure and flow, evenly atomizing the paint and finely spreading it on the sandblasted steel plate, strictly controlling the film thickness within the optimal range of 60 - 80μm. The sandblasted steel plate has been pretreated to have a slightly rough surface, providing ideal anchoring points for the paint and enhancing adhesion. The precise film thickness balances the protective and economic aspects of the coating. If it is too thick, it is prone to cracking; if it is too thin, it is difficult to resist erosion. This range ensures the even distribution of stress in the coating during boiling and resists water vapor penetration.

沸水试炼，彰显卓越本色

The Boiling Water Trial, Demonstrating Outstanding Quality

当喷涂完毕、漆膜固化的样板置入沸腾水中开启 8 小时极限挑战时，方见这套方案的真章。在水温 100℃的剧烈翻滚水汽冲击下，普通涂层或迅速软化、起泡、剥落，而 HDE8118 + HDH6815 涂层却傲然挺立。漆膜表面始终平整光滑，无丝毫起泡、皱缩迹象，色泽均匀，仿佛时间凝固；内部结构紧密严实，水汽无缝可入，得益于独特环氧交联体系，化学键稳固坚韧，分子链未因高温湿热断裂或松弛，牢牢守护钢板基体，历经 8 小时 “水深火热” 仍完好如初，为金属制品在厨卫、湿热工业环境等场景应用提供坚实保障。

When the sprayed and cured sample plate is placed in boiling water for an 8-hour extreme challenge, the true capabilities of this solution are revealed. Under the violent impact of rolling water vapor at a water temperature of 100°C, ordinary coatings may quickly soften, blister, or peel off, while the HDE8118 + HDH6815 coating stands firm. The surface of the paint film remains smooth and flat throughout, without any signs of blistering or wrinkling, and the color is uniform, as if time has stood still. The internal structure is tight and impenetrable to water vapor. Thanks to the unique epoxy crosslinking system, the chemical bonds are stable and tough, and the molecular chains do not break or relax due to high-temperature humidity, firmly protecting the steel plate substrate. After enduring 8 hours of "severe trials", it remains intact, providing a solid guarantee for the application of metal products in kitchen and bathroom, humid industrial environments, and other scenarios.
