Datec Coating Inc. is "a Canadian technology company that specializes in heating solutions that enablemanufacturers to optimize the performance of their products". Their core business lies around their patentedunique thick film technology involving a processing temperature under 400°C that enables printing heatingelements directly onto a wide range of materials, including low melting point materials, such as aluminum, andmaterials where thermal expansion mismatch would be a severe issue with other processes, such as mica,giving its customers a unique design flexibility for a wide-range of application and products. While manypossible new applications of Datec thick film process are envisioned, the technology is limited by drifts in theresistance of their resistive heaters. While mostly benign for their present line of business, this drift, could bedetrimental to some of Datec's prospective customers' applications. During the Engage project with Datec thathas been recently completed, a thorough investigation on the nature of the resistance drift in Datec's printedheater was performed. Structural and chemical analysis of Datec's printed resistors, performed by X-raydiffractometry, Raman spectroscopy, and thermo-gravimetric analysis, lead to the development of a theoryinvolving the presence of metastable transition components and their hydration when exposed to atmospherichumidity. Once the cause of the resistance drift was identified, preliminary investigations on possible solutionswere performed and a limited number of viable solutions proposed. Initial results on the first two solutionsproposed revealed that these ideas lead to appreciable improvements in the resistor structure and performances.The objective of this continuing project is now to implement the various solutions proposed, investigate theirefficacy, as well as the ease with which the solutions could be integrated into Datec's manufacturing process.The success of both the Engage and the present Engage PLUS project is meant to consolidate the existingcollaboration in order to explore and develop together the rapidly rising opportunities for business developmentin the more general and very promising field of printing of functional ceramics.

Datec Coating Inc.是一家加拿大技术公司，专门从事加热解决方案，使制造商能够优化其产品性能。他们的核心业务在于其专利的独特厚膜技术，涉及400°C以下的加工温度，可以将加热元件直接打印到各种材料上，包括低熔点材料，如铝，以及热膨胀不匹配将成为其他工艺严重问题的材料，如云母，为客户提供独特的设计灵活性，适用于广泛的应用和产品。虽然Datec厚膜工艺的许多可能的新应用被设想，但该技术受到其电阻加热器电阻漂移的限制。虽然这对他们目前的业务来说是有利的，但这种转变可能对Datec的一些潜在客户的应用程序有害。在最近完成的与Datec的Engage项目中，对Datec印刷加热器中电阻漂移的性质进行了彻底的调查。通过x射线衍射、拉曼光谱和热重分析，对Datec印刷电阻器进行了结构和化学分析，形成了一种理论，涉及亚稳过渡成分的存在及其暴露于大气湿度时的水合作用。一旦确定了阻力漂移的原因，对可能的解决方案进行了初步调查，并提出了有限数量的可行解决方案。对提出的前两种解决方案的初步结果表明，这些想法导致电阻结构和性能的显着改进。这个持续项目的目标现在是实施提出的各种解决方案，调查其有效性，以及将这些解决方案集成到Datec制造过程中的难易程度。Engage和目前的Engage PLUS项目的成功旨在巩固现有的合作，以便共同探索和开发在功能陶瓷印刷这一更普遍和非常有前途的领域快速增长的商业发展机会。
