Eugénie Charrière, global marketing and strategy director at Vencorex, highlights new developments, trends and challenges in plastic coatings. Interview by Kirsten Wrede

Vencorex全球市场营销和战略总监eugsamunnie charri接受克尔斯滕·弗雷德采访时,强调了塑胶涂料的新发展、趋势和挑战。

What are the most exciting applications for plastic coatings today?

Eugénie Charrière: In today’s dynamic landscape, plastic coatings have evolved significantly, particularly in critical end-use sectors like automotive and electronics. Within vehicle interiors and across consumer electronics, the demand for coatings that exhibit resilience against scratches, perspiration, sun-tan lotion, and offer enhanced aesthetic and tactile sensations is crucial. Vencorex has developed solutions to meet these complex requirements, like a crosslinker tailored for 2K waterborne polyurethane matte finishes, delivering enhancements in both scratch and chemical resistance.

在如今动态环境下,塑胶涂层在汽车和电子等关键终端用途领域变化显著.在汽车内饰及消费性电子产品领域,要求美学和手感的同时,也要求抗刮擦/防汗/防美黑剂等属性. Vencorex开发了满足这些复杂要求的解决方案,例如为2K水性聚氨酯哑光饰面定制的交联剂,可增强划伤和耐化学性。

How prevalent have plastic coatings based on renewable raw materials become?

Charrière: As new bio-based and biodegradable plastics are becoming commercially available, plastic coatings from renewable sources are rapidly gaining traction. A considerable research effort is ongoing in the industry reflecting a heightened emphasis on the replacement of fossil-based materials.

In the shorter term, plastic manufacturers are looking for energy efficiency for the painting lines, driven by cost-effectiveness and CO₂ emission reduction. We address this concern with a fast-drying crosslinker enabling stoving at lower temperatures of 2K polyurethane coatings.

随着新型生物基和可生物降解塑料的商业化,可再生资源的塑胶涂层正在迅速获得吸引力.大家十分重视其对传统石化材料的替代,纷纷大量开展相关的研究.

短期内,基于成本效益和二氧化碳减低排放的需求,塑胶涂装生产商寻求的是能源效率.这个问题,可通过快干型交联剂解决,该交联剂能让2K聚氨酯涂料在较低温下烘烤。

What are the general challenges of coating plastic substrates, and how can they be overcome?

Charrière: Addressing the challenges inherent in coating plastic substrates requires a nuanced approach informed by industry expertise. Foremost among these challenges is the recycling of coated plastic components, a topic that has garnered significant attention within the research community. Notably, the European-founded project DECOAT leads the charge, pioneering smart additives for seamless integration into coating formulations. These additives facilitate controlled disbonding under specific trigger conditions, enhancing recycling efficacy. DECOAT and similar initiatives underscore the industry’s commitment to sustainability and innovation, leveraging advanced materials and cutting-edge technologies.

塑胶涂料目前最大的挑战,是已涂装塑胶部件的回收问题,这个问题引起了专家们极大的关注.而解决这个问题,需要的是基于专业知识上的细致研究.而欧洲成立的DECOAT项目引领了这一潮流,通过开发智能添加剂,无缝整合进涂料配方,在特定条件下帮助涂料触发可控性剥离,从而提高回收效率. DECOAT及同类研究举措,在先进材料和尖端技术之间找到平衡点,强调了涂料行业对可持续发展和创新的承诺.
