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的性能”。他们的核心业务是其专利的独特厚膜技术，涉及400°C以下的加工温度，使印刷加热元件直接到各种材料，包括低熔点材料，如铝，和材料的热膨胀不匹配将是一个严重的问题，与其他工艺，如云母，给客户一个独特的设计灵活性，为广泛的应用和产品。虽然Datec厚膜工艺有许多可能的新应用，但该技术受到电阻加热器电阻漂移的限制。虽然大多数情况下对他们目前的业务线是良性的，但这种漂移可能对Datec的一些潜在客户的应用程序不利。在最近完成的与Datec的Engage项目中，对Datec打印加热器的电阻漂移性质进行了彻底的调查。通过X射线衍射法、拉曼光谱法和热重分析法对Datec的印刷电阻器进行了结构和化学分析，得出了一种理论，该理论涉及亚稳过渡组分的存在及其在暴露于大气湿度时的水合作用。一旦确定了电阻漂移的原因，就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。前两个方案的初步结果表明，这些想法导致电阻器结构和性能的明显改善。这个持续项目的目标是实施所提出的各种解决方案，研究其有效性，以及解决方案可以轻松集成到Datec的制造过程中。Engage和目前Engage PLUS项目的成功意味着巩固现有的合作，以探索和共同发展的业务发展迅速上升的机会，在更普遍和非常有前途的领域印刷的功能陶瓷。
