Polyurethane coatings: Traditional market changing

聚氨酯涂料:传统市场变化
Tense situation: Supply problems and regulation are a challenge in the polyurethane coatings market. However, this current challenging development in the industry is also encouraging a shift to more sustainable products.
紧张局势:供应问题和监管是聚氨酯涂料市场的一个挑战.然而,目前该行业的挑战也鼓励了行业转向更可持续的产品.
The positive environmental and regulatory profile of water-borne solutions such as polyurethane dispersions is a major factor in this technology gaining market share.
In 2020, polyurethane coatings accounted for 5.9 million tonnes sold globally, which was around 11 % of the total paints and coatings market (53.6 million tonnes) and valued at EUR 28 billion according to José Bottino at market research company IRL. This is predicted to grow to 7.6 million metric tonnes and 11.7 % of the market by 2025.
对水性涂料的有利环境和监管优势,使得水性产品(如聚氨酯分散体)在市场份额上比利增加的主要原因.
根据市场研究公司IRL的José Bottino的数据,2020年,聚氨酯涂料在全球销售了590万吨,约占涂料市场总量(5360万吨)的11%,价值280亿欧元.预计到2025年,这一数字将增长到760万吨,占市场份额的11.7%.
In terms of end use application, the largest share of PU coating sales in 2020 was in the protective coatings segment, with 32.1 % of the market. The industrial wood coatings segment made up 24.7 % of sales. These segments have been gaining share from alkyds recently and are set to grow further. IRL attributes investments in infrastructure as driving the protective coatings market and growing construction for driving industrial wood coatings in some regions despite overall volumes declining.
就终端应用而言,2020年PU涂料销售的最大份额是防护涂料领域,占市场份额的32.1%.其中工业木器涂料部分占销售额的24.7%.
这些领域最近从醇酸中获得了份额,并将进一步增长.IRL认为,尽管总体销量下降,但基础设施投资推动了保护涂料市场的发展,并且在一些地区推动了工业木器涂料的建设.
Protective performance trends
防护性能趋势
Miriam Peralta at Lubrizol, says that the main trends for protective coatings are to “keep improving performance with more optimised systems (fewer coats), improve emissions (reduce the amount of solvents and increase the solid content), and improve the carbon footprint of the products (without reducing performance) by using bio-solvents, systems with better curing profiles (to reduce the amount of energy used), etc.”
Lubrizol的Miriam Peralta表示,保护涂料的主要趋势是“通过更优化的系统(更少的涂层)不断提高性能,改善排放(减少溶剂量,增加固含),并通过使用生物溶剂、具有更好固化性能的系统(减少能源使用量)等来改善产品的碳足迹(在不降低性能的情况下).”
PU coatings is still largely a traditional market
聚氨酯涂料在很大程度上仍是一个传统市场
Currently, solvent-based, two-component (2K) systems and high-solids PU systems represent the highest proportion of the total PU resin type for highly demanding applications such as protective coatings, according to Lubrizol. PU coatings is still largely a traditional market that relies heavily on solvent-borne chemistry, which makes up 82 % of the volume and 76 % of sales according to Mike Growney at market research company KNG. There is a gradual shift towards more water-borne coatings, which Growney predicts are growing nearly twice as fast as the 3 % rate he forecasts for global market growth.
目前,溶剂型双组分(2K)系统和高固体PU系统在高要求应用(如防护涂料)中所占比例最高.据市场研究公司KNG的Mike Growney称,聚氨酯涂料在很大程度上仍然是一个严重依赖溶剂化学的传统市场,占总量的82%和销售额的76%.人们逐渐转向更多的水性涂料, Growney预测, 他预测的水性涂料全球市场增长速度3%,但现在实际的增长速度几乎是预估的两倍.
IRL rates the market share of solvent-borne chemistry more conservatively at 66.5 % of total sales and predicts this will decrease to 63.9 % by 2025 in favour of increases in the water-borne, radiation curing and powder PU coating sectors.
IRL较为保守地估计,溶剂型化学产品的市场份额为总销售额的66.5%,并预测到2025年这一份额将下降至63.9%,而水性、辐射固化和粉末PU涂料行业将有所增长.
The positive environmental and regulatory profile of water-borne solutions such as polyurethane dispersions is a major factor in this technology gaining market share. Peralta say that significant performance improvements have been made in polyurethane dispersions in recent years, making them comparable, for instance, to some commonly used 2K systems. She adds that “some new polyol technologies in the market (i.e. polyamide polyols) or polyurethane dispersions with higher solid contents are making the gap in performance between 1K and 2K smaller and smaller.”
水性解决方案(如聚氨酯分散体)的积极环境和监管概况是该技术获得市场份额的主要因素.Peralta表示,近年来聚氨酯分散体的性能有了显著提高,例如,可以与一些常用的2K系统相媲美.她补充说:“市场上一些新的多元醇技术(即聚酰胺多元醇)或具有更高固体含量的聚氨酯分散体,正在使1K和2K之间的性能差距越来越小.”
