瀚岱化学高固含解决方案-8123B+2828 Hantai Chemical's High - Solid - Content Solution - 8123B + 2828

一、项目背景

I.Project Background

水性高固含产品在未来应用前景极为广阔，有望在替代现有含挥发性有机化合物（VOC）的溶剂型高固含产品方面发挥重大作用。然而，当前部分客户反馈，一些水性产品在将漆膜喷涂至 200、300、400微米时，会出现慢干甚至开裂的情况。针对这一问题，瀚岱化学强势推出全新高固含解决方案。

Water - based high - solid - content products have extremely broad application prospects in the future and are expected to play a significant role in replacing the existing solvent - based high - solid - content products containing volatile organic compounds (VOC). However, currently, some customers have reported that when some water - based products spray the paint film to 200, 300, or 400 micrometers, slow - drying or even cracking may occur. In response to this problem, Hantai Chemical strongly launched a brand - new high - solid - content solution.

二、测试详情 

II. Test Details

1.样板准备

1.Sample Preparation

-本次测试使用马口铁板作为样板，马口铁板因其优良的耐腐蚀性、出色的加工成型性等特点而备受青睐，不过，在高固含涂料与其附着结合方面却存在潜在挑战，而这也正是本次解决方案的核心关注点所在。

In this test, tinplate was used as the sample. Tinplate is favored for its excellent corrosion resistance and outstanding processing formability. However, there are potential challenges in the adhesion and combination of high - solid - content coatings with it, and this is also the core concern of this solution.

2.干燥方式和测试条件设定

2.Drying Method and Test Condition Setting

-在本次测试中，需要特别强调的是，将涂有高固含涂料且漆膜厚度接近1000微米的马口铁板置于室温环境下干燥七天。要知道，达到如此高的漆膜厚度并非易事，且这样的高膜厚极易出现慢干甚至开裂的情况。

In this test, it should be particularly emphasized that the tinplate coated with high - solid - content coating and with a paint film thickness close to 1000 micrometers was dried in a room - temperature environment for seven days. It should be noted that achieving such a high paint film thickness is not easy, and such a high film thickness is extremely prone to slow - drying or even cracking.

3.测试过程及结果

3.Test Process and Results

-干燥七天后，对喷涂后的每块马口铁的膜厚进行测量并予以标识。接着，对每块马口铁进行弯曲测试，以弯曲测试的方式检查漆膜是否开裂，且每块的弯曲角度均超过 120°。对样板进行全面检查后发现，涂料依然紧密地附着在马口铁板上。

After drying for seven days, the film thickness of each sprayed tinplate was measured and marked. Then, a bending test was performed on each tinplate to check whether the paint film was cracked by means of the bending test, and the bending angle of each was more than 120°. After a comprehensive inspection of the samples, it was found that the coating was still tightly adhered to the tinplate.

经过这一系列严谨的弯曲测试，可以得出结论：在干燥七天后，高固含涂料在马口铁板上无论面临何种弯曲程度，均表现出卓越的附着力，有效避免了开裂问题。具体的测试数据与实际表现充分表明，我们所研发的高固含解决方案下的产品 8123B+2828，在这种特定的干燥和弯曲测试条件下，能够与马口铁板完美结合，完全符合实际应用中的高附着力要求。

After this series of rigorous bending tests, a conclusion can be drawn: after drying for seven days, the high - solid - content coating exhibits excellent adhesion on the tinplate regardless of the degree of bending, effectively avoiding the problem of cracking. The specific test data and actual performance fully demonstrate that our product 8123B + 2828 under the high - solid - content solution developed by us can be perfectly combined with the tinplate under these specific drying and bending test conditions, fully meeting the high - adhesion requirements in practical applications.
