Although solvent-borne coatings have their place in the market, the percentage of water-borne coatings in the global paint and coatings market should hold stable or grow in the coming years as performance improves and the need for more sustainable products continues.

尽管溶剂型涂料在市场上占有一席之地，但随着性能提高和对更可持续产品的需求不断增加,水性涂料在全球油漆和涂料市场中的比例将在未来几年保持稳定或增长。

Global overview

Water-borne coatings are estimated to be just 50 % of the volume of the global paint and coatings market. Of the estimated 48 billion litres of paint coatings sold globally, 24.4 billion is estimated to be water-borne. In value terms, we estimate the global market for water-borne coatings to be EUR 82.1 billion of the estimated EUR 178 billion global paint and coatings market.

Most of the market for water-borne coatings is in the decorative market. Of the 24.4 billion litres of global water-borne coatings we estimate that 88 % of it or 21.5 billion litres is in the decorative market. Within the non-decorative industrial coatings market, water-borne coatings are spread out among various segments.  Some of the major ones include automotive and transportation, wood, and traffic marking paints.

全球概览

据估计,水性涂料仅占全球油漆和涂料市场的50%.全球估计480亿升油漆涂料的销售额中,估计有244亿升是水性涂料.在价值方面,全球油漆和涂料市场营业额估值为1780亿欧元,其中水性涂料市场为821亿欧元.

水性涂料的大部分市场是在装饰涂.在全球244亿升水性涂料中,估计其中88%/215亿升用于装饰涂料市场.在非装饰工业涂料市场中,水性涂料也在包括汽车和运输、木材和交通标志涂料等各个领域发挥作用。

On a regional basis, Asia is the largest market for water-borne products. That is not a surprise since Asia comprises an estimated 57 % of the volume of the global paint and coatings markets.  All the major markets in Asia including China, India, Japan, Korea, Southeast Asia, Australia and New Zealand, and Central Asia have significant decorative coatings markets and thus have significant water-borne markets.

The chemistries of water-borne coatings include acrylic-based formulations (including 100 % acrylics, styrene acrylics, and vinyl acrylics) as well as latex chemistries like poly-vinyl acetates.  Additionally, polyurethane dispersions or PUDs have seen lots of growth over the years. PUDs still make up a relatively small percentage of the water-borne market at an estimated 1.5 % but they find their use in wood, flexible packaging, transportation, and other coatings segments.  Finally, water-borne epoxy is another large chemistry segment of the market. Water-borne epoxies are mainly used in automotive, transportation, and general industrial segments of the market.

从区域来看,亚洲是水性产品的最大市场,鉴于亚洲约占全球油漆和涂料市场总量的57%,这一情况并不奇怪.包括中国、印度、日本、韩国、东南亚、澳大利亚和新西兰以及中亚在内的亚洲所有主要市场.都有众多装饰涂料市场,因此水性涂料市场众多.

水性涂料主要包括丙烯酸基配方（包括100%丙烯酸,苯乙烯丙烯酸和乙烯丙烯酸）及乳胶配方(如聚醋酸乙烯酯);此外,聚氨酯分散体（pud）近年来也有很大增长,目前pud在水性涂料市场中占比相对较小,约为1.5%,但在木材、软包装、运输和其他涂料领域都有应用.最后,主要用于汽车、运输和普通工业市场的水性环氧树脂市场也很巨大.

Advantages and disadvantages of water-borne products

Water-borne coatings are favoured for their low volatile organic compound (VOC) content, which makes them favoured by paint and coatings companies trying to promote more sustainable products. As governments around the world implement more stringent VOC requirements, this has resulted in a shift towards more water-borne products.

One interesting trend occurring in various markets is that while the gram per litre of the paint and coatings is still important, some regulatory authorities are becoming more concerned about the total site emissions; meaning the total VOC emissions of a factory or building site. This is especially true in urban areas where there is more of a concern about the adverse effects of air pollution.

水性涂料产品的优缺点

随着世界各国政府实施更严格的VOC要求,水性涂料因其挥发性有机化合物（VOC）含量低,受到有更可持续产品解决方案需求的公司的青睐.市场也更向水性转变.

虽然油漆和涂料的每升克数仍然很重要,但人们越来越在意空气污染,监管机构们越来越关注现场排放总量,既工厂或建筑工地的总VOC排放量,越是城市,关注越多.

Despite the benefits of water-borne paint and coatings, there are some drawbacks. In some cases, water-borne products are more expensive than the corresponding solvent-borne products. Also, the water-borne products sometimes do not perform as well as the corresponding solvent-borne products. Durability, adhesion, and drying time can be worse with water-borne products.

Another issue is that some water-borne products can have a larger carbon footprint. The energy to dry or cure a water-borne can be more than that of a solvent-borne product. As we all know, carbon footprint issues are becoming more and more important factor in the paint and coatings industry.

Some other drawbacks of water-borne coatings is that their cure time can be humidity and temperature sensitive, moisture sensitivity (until fully cured, water-borne products are more sensitive to rain, dew, and condensation), and there are shelf-life and storage concerns (damage upon freezing).

水性油漆和涂料有好处,但也有些缺点.有时候,水性产品比对应溶剂型产品更贵;有些水性产品不如溶剂型产品性能好,在耐久性、附着力和干燥时间方面表现更差;而且有些水性产品可能会产生更大的碳足迹,干燥,固化水性产品比溶剂型产品更费能量,而碳足迹问题正在成为油漆和涂料行业的阻碍;此外,水性涂料固化时,可能对湿度/温度/水分更敏感（完全固化前,水性产品对雨,露水和冷凝更敏感）,且存在保质期和储存问题（冻结时损坏）.

Most of the above concerns are being worked on by the raw material suppliers and paint and coatings companies. Recent advancements in water-borne paints and coatings have focused on enhancing sustainability advantage and performance attributes of the paint and coatings.

·         Continued use of WB for current paint and coatings systems: When we interview users of paint and coatings, there is continued demand for water-borne products. Applicators and end users of paint and coatings like water-borne paint and coatings since they provide better and safer working conditions for the contractors and factory workers.

·         Continued improvements in sustainability: Paint and coatings companies as well as raw material suppliers continue to look for ways to remove or eliminate toxic or non-environmentally friendly products from water-borne paints. For example, using less harmful biocides is a major focus area.

·         Faster curing systems: Paint and coatings companies continue to look for opportunities to speed up the curing process for water-borne products. Also, some work is being done on reducing the temperature for curing. Temperature reduction also helps reduce the carbon footprint of a coating solution. Some of this work is related to the curing agents that are used.

·         Durability: To address the durability concerns, more water-borne 2K epoxies and urethanes are being developed. Also, some hybrid systems like alkyd-acrylics and silicone-acrylics are being developed, which improve durability.

·         Better adhesion: New formulations are being developed with better adhesion to less than ideal prepped surfaces.

原材料供应商和油漆涂料公司正在解决上述大部分问题.他们最新进展集中在提高涂料的可持续性优势和性能属性上。

• 继续使用WB: 油漆和涂料的用户对水性产品的需求持续存在.涂料的操作者和终端用户们更喜欢水性涂料,因为它们为承包商和工厂工人提供了更好更安全的工作条件。


• 对可持续发展的持续改进:涂料公司及原材料供应商继续从水性涂料中去除或减低有毒/非环保产品。例如,使用危害较小的杀菌剂是个主要研究方向。


• 更快的固化系统:继续寻找加快水性产品固化过程的方法,并努力降低固化温度.挑选合适固化剂降低固化温度也有助于减少涂料的碳足迹.


• 耐久性:开发更多水性2K环氧树脂和聚氨酯以提升持久性,同时开发混合涂料系统,例如醇酸-丙烯酸和硅-丙烯酸等,以提高耐久性。


• 更好的附着力:为不太理想的已处理表面,开发附着力更好的新配方

Also, there are raw materials that use bio-based products, and thus further enhance the sustainability advantages of water borne products. The paint and coatings industry needs to continue pushing these advances forward, so that water-borne products can continue to grow, and applicators and end-users can continue to reap the benefits of using water-borne products. 此外,可选用生物基原材料,以进一步增强水性产品的可持续性优势.油漆和涂料行业需要继续推动这些进步,以便水性产品能够继续增长,让施工人员和终端用户也能持久享受水性产品的好处.

Conclusion

Water-borne coatings are an important part of the global paint and coating industry. They continue to be mostly used in decorative coatings but are also growing in the non-decorative industrial coatings segments. Cost, performance, and application issues have resulted in less use of water-borne products in the non-decorative industrial coatings segments. But advances in chemistries and formulations are results in more and more use. As the technology improves, we expect more use of water-borne coatings dues to their inherent sustainability advantages.

结论

水性涂料是全球油漆和涂料行业的重要组成部分,将继续主要用于装饰涂料,但在非装饰工业涂料领域也在增长.成本、性能和应用问题导致水性产品在非装饰工业涂料领域的用处减少.但化学和配方的进步增加了水性涂料的应用潜力.随着技术的进步,基于水性涂料固有的可持续性优势,我们期望更多地使用水性涂料.
