Globally, the lion’s share is attributable to the Asia-Pacific region. The region accounts for a good half of the volume (17.28 million tons) and about 43 % of the value. Europe ranks second with just under 7 million tons worth EUR 21.5 billion. For North America, the market researchers determined a volume of 6.1 million tons and a value of EUR 19.5 billion. For South America, MaM estimates the volume at 2.44 million tons and around EUR 6.7 billion. A similar order of magnitude results for the Middle East and Africa region, 2.12 million tons and a value of EUR 5.9 billion. They expect further growth in the coming years. The global compound annual growth rate (CAGR) is 4.9 % through 2026, according to MaM. The highest growth, with a CAGR of 6.6 %, is expected in Asia-Pacific. The Middle East and Africa region is just below the global average at 4.5 %. In Europe, the figure is expected to be a moderate 2.9 %. In value terms, water-borne coatings are growing at a CAGR of 3.5 %. Asia Pacific (5.1 %) and the Middle East and Africa (3.6 %) are also above the global average. For Europe, the market researchers expect a growth rate of only 2 %.

从全球来看,最大的份额来自亚太地区.该地区占总量的一半(1728万吨)和价值的43%左右.欧洲排名第二,接近700万吨,价值215亿欧元.对于北美市场,市场研究人员确定的数量为610万吨,价值195亿欧元.对于南美,MaM估计产量为244万吨,约67亿欧元.中东和非洲地区也有类似的数量级,为212万吨,价值59亿欧元.他们预计未来几年还会进一步增长.

根据MaM的数据,到2026年,全球复合年增长率(CAGR)为4.9%.预计亚太地区的复合年增长率最高,为6.6%.中东和非洲地区仅为4.5%,略低于全球平均水平.在欧洲,这一数字预计为2.9%.就价值而言,水性涂料正以3.5%的复合年增长率增长.亚太地区(5.1%)、中东和非洲(3.6%)也高于全球平均水平.对于欧洲,市场研究人员预计增长率只有2%.

Thomas Bernhofer of Synthomer agrees with the growth forecasts. The company expects demand to continue to develop positively with a CAGR of 5 %. “We continue to see the market as attractive and interesting, with individual segments offering above-average growth opportunities. We expect accelerated development in the coming years due to demand for sustainable coating solutions and support from the legislative side, such as the Green Deal,” says Bernhofer.

Synthomer的托马斯·伯恩霍夫(Thomas Bernhofer)对这个增长预测持同意意见.该公司预计需求将继续以5%的复合年增长率积极发展.“我们仍然认为市场是有吸引力和有趣的,个别细分市场提供了高于平均水平的增长机会.由于对可持续涂料解决方案的需求和立法方面的支持,如绿色协议Green Deal,我们预计在未来几年加速发展.”

The market for water-borne coatings is a very interesting area of the paints and coatings industry that will replace part of the solvent-based sector, Dr Dirk Schwöppe of Synthopol is certain. “This trend can already be observed today. Theoretically, all polymers from the solvent-based area are available, but the way these prepolymers get into the water by means of additives is much more complex,” explains the R&D manager. In the past, aqueous products were usually more costly and complicated to process. “With rising raw material costs and requirements toward sustainability, there is almost no way around water-borne systems, even if there are still challenges in the area of application technology and performance. That’s why we expect the market to double in the next 15 years,” adds Schwöppe.

理论上,溶剂型区域的所有聚合物都是可用的,但这些预聚体通过添加剂进入水中的方式要复杂得多,”在过去,含水产品通常成本更高,处理起来也更复杂.“随着原材料成本的上升和对可持续性的要求,尽管在应用技术和性能方面仍然存在挑战,但几乎没有办法绕过水性系统.这就是为什么我们预计未来15年水性市场将翻一番,”Schwöppe补充道.

The market for water-borne coatings is growing continuously worldwide. This is due to increasing legal requirements for environmental compatibility and sustainability worldwide, emphasises Dr Nils Kottner from Münzing. “Overall, the market for water-borne coating systems is growing faster worldwide than the coatings market as a whole. Responsible for this are labeling obligations, regulations and legal requirements. Examples include VOC emission restrictions specifically in Europe, North America and China. Demands for improved sustainability of coating systems and compliance with green building standards are other key aspects driving the growth of water-based coatings and paints. Meanwhile, coating systems based on renewable raw materials and consideration of life cycle analysis and carbon footprint are becoming increasingly important,” says Kottner.

水性涂料市场在全球范围内持续增长.来自Münzing的Nils Kottner博士强调,这是由于全球对环境兼容性和可持续性不断增加的法律要求.“总体而言,水性涂料系统市场在全球范围内的增长速度快于整个涂料市场.这是由于相关机构标签,法规和法律要求.例如欧洲、北美和中国的VOC排放限制.

The largest part of the market for water-borne coating systems is the architectural coatings segment. Thus, Kottner still sees the greatest current potential in the construction segment here as well. “Especially in China and developing countries, there is massive investment in infrastructure, housing projects and industrial buildings. Thus, an increased demand for architectural coatings, including interior paints and basecoats, is to be expected. But wood and furniture coatings, as well as water-based printing inks, are also definitely growth areas.

水性涂料系统市场的最大份额是在建筑涂料领域.因此,Kottner仍然认为目前建筑领域的潜力最大.“特别是在中国和发展中国家,在基础设施,住房项目和工业建筑方面有大量投资.因此,对建筑涂料,包括室内涂料和底漆的需求将会增加.但木材和家具涂料,以及水性印刷油墨,也肯定是增长领域.

In the industrial coatings sector, the share of water-borne coating systems is significantly lower. But here, too, there are more and more coating systems with thoroughly comparable properties to solvent-based coatings, explains Kottner. Wouter Jongepier of Westlake Epoxy considers water-borne protective coatings to be an application area that still requires a high level of expertise in terms of formulation and application. However, when water-borne epoxy coatings are properly formulated and applied, they can match the performance of solvent-based systems.在工业涂料领域,水性涂料系统的份额明显较低.Kottner解释说,但在这方面,也有越来越多的水性涂层系统,水性与溶剂型涂料的性能完全相当.Westlake Epoxy的Wouter Jongepier认为水性防护涂料在配方和应用方面仍然需要高水平的专业知识.然而,当水性环氧涂料的配方和应用得当,它们可以匹配溶剂型体系的性能.

“The switch from solvent-based to water-borne corrosion protection coatings is heavily influenced by legislation. European requirements regarding the reduction of volatile organic compounds (VOCs) seem to be stagnating. In this respect, demand is driven more by general industrial growth and stricter specifications in certain segments, such as the railroad sector. In Europe, we see healthy growth in demand for anticorrosion coatings overall, but this trend could be temporarily weakened by current supply chain disruptions and a potential recession,” Jongepier says. He sees the greatest potential in the application of water-based protective coatings on larger metal structures such as trains, transport vehicles or construction machinery under industrial conditions.

“从溶剂型到水性防腐涂料的转变在很大程度上受到立法的影响.欧洲关于减少挥发性有机化合物(VOCs)的要求似乎停滞不前.在这方面,需求更多地受到一般工业增长和某些领域(如铁路部门)更严格的规范的推动.在欧洲,我们看到防腐涂料的整体需求健康增长,但这一趋势可能会暂时受到当前供应链中断和潜在衰退的影响,”Jongepier说.他认为在工业条件下的火车,运输车辆或工程机械等大型金属结构上应用水性保护涂层的潜力最大.

For Schwöppe, strongly fluctuating climatic conditions (temperature/humidity) and the properties such as flow, processability, open time, gloss and resistance, which are not yet fully approachable compared to solventborne coatings, represent a challenge. This means that applications in the industrial sector, such as industrial coatings, marine or aircraft paints, and heavy water-based corrosion protection are rare, he said.

对于Schwöppe来说,剧烈波动的气候条件(温度/湿度)和流动性、可加工性、打开时间、光泽度和耐腐蚀性等性能方面,水性涂料与溶剂型涂料相比还有较大差距,这是一个挑战.他说,这意味着在工业领域的应用,如工业涂料、船舶或飞机涂料,以及重水性腐蚀防护方面,水性涂料表现仍然有潜力.

Although Bernhofer sees the greatest growth potential in the architectural coatings/trim paints sector, he says that it is precisely here that the replacement of traditional solvent-borne architectural coatings has not yet been solved satisfactorily from a technical point of view due to processor requirements (e.g. long open time, achievable high gloss), and therefore the changeover remains slow.

“We see their use in areas of industrial coating as limited for technical reasons, especially where powder coatings and radiation-curing 100% systems have become established, and in plastics coating,” adds Bernhofer. Jongepier takes a similar view. “In segments that can be covered by powder coatings, the application of water-based systems remains limited. A major challenge to water-borne systems continues to be their application under less controllable conditions, such as highly variable and low temperatures, as well as high humidity. Therefore, the use of solvent-free or high-solids technologies may be preferred for very extensive constructions in shipbuilding and offshore applications,” he explains.

Bernhofer补充道:“由于技术原因,我们认为它们在工业涂料领域的应用受到了限制,特别是在粉末涂料和100%辐射固化系统的领域,以及在塑料涂料领域.”Jongepier持类似观点.“在可以被粉末涂料覆盖的部分,水性系统的应用仍然有限.水性系统的一个主要挑战仍然是它们在例如高度可变和低温,以及高湿度等不太可控的条件下的应用,因此,在造船和海上应用中,无溶剂或高固体技术的使用可能是广泛应用的首选.”

Sustainability is an important trend in water-borne coatings. In general, the use of sustainable systems is becoming increasingly important, Kottner says of the trends in water-borne coatings. Specifically, he says, this is about achieving a long service life combined with long-lasting functionality. “In our opinion, the trend towards sustainable raw materials/lacquers and the environmentally conscious certification of these, such as Blue Angel, Nordic Swan, EU Ecolabel, can no longer be stopped. The reduction of co-solvents in the direction of “Zero VOC”, which primarily influence film formation, is also being pushed further. It is not yet possible to estimate what impact the extension of REACH will have on polymers. Qualification of existing products could require a considerable amount of R&D or application technology resources, which would no longer be available for further product development. That would slow down progress,” says Schwöppe.可持续性是水性涂料的一个重要趋势.总的来说,可持续系统的使用正变得越来越重要,Kottner谈到了水性涂料的趋势.他说,具体来说,这是为了实现较长的使用寿命和持久的功能.“在我们看来,可持续原材料/漆的趋势,以及这些产品的环保意识认证,如蓝天使、北欧天鹅、欧盟生态标签,已经无法停止.在“零VOC”方向上减少影响成膜的助/共溶剂,也正在进一步推进.目前还不可能估计REACH的扩展将对聚合物行业产生什么影响.现有产品的鉴定可能需要相当数量的研发或应用技术资源,这些资源将不再用于进一步的产品开发.这将减缓进展,”Schwöppe说.

For Jongepier, the frontiers of water-borne epoxy systems are currently shifting toward co-solvent-free systems. “We are continuously working on expanding the application window and robustness of water-borne epoxy systems. As an industrial company, we are improving the carbon footprint of our coating materials in line with the European Green Deal,” Jongepier says.

Bernhofer observes three main trends. “A continuous improvement in the achievable mechanical-technological resistance, e.g. weather-/ UV-resistance, chemical resistance for furniture coatings, block resistance and corrosion protection for metal coatings (up to C5 high). Another trend is the improvement of application properties and enlargement of the application window, such as extended open time and better early rain resistance. The third trend is to improve sustainability, e.g. further VOC reduction, use of renewable raw materials.”

Bernhofer观察到涂料行业发展的三个主要趋势.“不断提高可达到的机械-技术阻力,例如耐气候/紫外线,家具涂层的耐化学腐蚀性,金属涂层的抗阻塞性和耐腐蚀性(高达C5级).另一个趋势是应用性能的提高和应用窗口的扩大,如延长开放时间和更好的抗早雨性.第三个趋势是提高可持续性,例如进一步减少VOC,使用可再生原材料.”
