Interview: "Some challenges remain"

从溶剂型涂料过渡到水性涂料-仍然存在一些挑战

Interview by Damir Gagro

Although water-borne epoxy performance has advanced significantly over the past 40 years, there are some challenges that remain when transitioning from solvent- to water-borne coatings, says Daniel J. Weinmann, market development manager at Westlake Epoxy.

Westlake环氧树脂公司市场开发经理Daniel J. Weinmann表示,尽管水性环氧树脂的性能在过去40年里有了显著的进步,但从溶剂型涂料过渡到水性涂料仍然存在一些挑战.

What are the remaining challenges in the transition from solvent- to waterborne coatings?

从溶剂型涂料过渡到水性涂料还存在哪些挑战?

Daniel J. Weinmann: Over the past few decades, waterborne epoxy coatings have significantly improved their capability to deliver epoxy performance in real world applications. For commercial coating formulations, the solvent content in waterborne epoxy coatings has dropped from 150 g/L VOC to less than 50 g/L VOC: in some cases, even approaching zero VOC levels. Even at ultra-low solvent content, these waterborne epoxy formulations provide superior adhesion, higher chemical resistance, and excellent corrosion resistance. Although waterborne epoxy performance has advanced significantly over the past 40 years, there are some challenges that remain when transitioning from solvent- to waterborne coatings.  These challenges fall into two primary categories:  formulation development and application properties.

Daniel J. Weinmann:在过去的几十年里,水性环氧涂料在实际应用中显著提高了环氧性能.商业涂料配方里,水性环氧涂料中的溶剂含量已从150 g/L VOC下降到50 g/L VOC以下:在某些情况下,甚至接近零VOC水平.

即使在超低溶剂含量,这些水性环氧树脂配方提供优越的附着力,更高的耐化学性和优异的耐腐蚀性.尽管水性环氧树脂的性能在过去的40年里有了显著的进步,但从溶剂型涂料过渡到水性涂料仍然存在一些挑战.这些挑战主要分为两类:配方研发和应用特性.

In formulation development, the main challenges are robustness, cost and component stability.  Wate....
