What are the important physico chemical parameters when formulating inks and how to characterize and optimize them. Recording kindly provided by Krüss.

This webinar was organised by UL prospector in November 2021 and discusses the typical defects found in architectural coatings and offers product recommendations to solve these issues.

This is a re-recording of the paper given at Inkjet Congress 2019. "Promoting Curing Speed: Ideal Surfactants for LED Curing Inkjet Inks"

Wall paints are a very important application within Architectural Coatings - and renewing them is quite laborious. Optimizing the resistance to damage and wear leads to more economical and sustainable paint formulations, as it makes renovation of e.g. façades with the costly installation of scaffolding redundant. One particular headache for freshly painted façades can be the formation of so called snail trails causing an uneven appearance when there is high humidity or rain. New specialty fillers help to prevent these problems and allow to formulate very long-lasting beautiful films when formulated e.g. with optimized hydrophobing agents. For interior coatings, innovative fillers also play a major role for optimization of mechanical resistance e.g., burnish phenomena - in addition, the use of suitable surface-active agents facilitates the optimization of scuff and chemical resistance. Studies of film formation help to understand and optimize both interior and exterior formulations.

Analytical methods to describe the performance of silicone based surface control additives in waterborne wood and furniture coatings. Learn more about current trends in wood coatings, performance profile of surface control additives based on silicone chemistry in waterborne wood coatings, the results based on analytical methods and capability of spherical precipitated silica particles to enhance the mechanical resistance of coating surfaces.

This course provides some insights on the different types of wood coating technologies. For each technology, we will describe its advantages, disadvantages and key functionalities.

Deep insight to global vehicle production and OEM market perspective.

Siloxane-based additives are critical tools in coating applications because their structures can be varied in order to provide a broad range of performance benefits in many types of formulations and chemistries. An attempt is made to clarify the general structure-property relationships that drive the performance attributes of siloxane additives and detail the continuum that exists between wetting, leveling, defoaming and slip within this chemistry class.

Why certain wetting agents spread over certain substrates, and fail at wetting out other? What are the specifics of packaging substrates, and how do these differ from those made of natural polymers used to make porous materials such as paper, corrugated board and textiles? How are surfaces functionalized to improve their wettability? How important is the process dynamics for the selection of wetting agent? Answers to these and many more questions are provided as the topic of substrate wetting gets revisited from the ‘inkjet’ perspective.

Recorded Webinar: This webinar shows you how to enhance the beauty of your floor with a range of coating additives from Evonik.

Wetting challenging substrates has become a major hurdle in ink and coating development due to the varying wetting and absorption properties of materials used. Regulatory changes demand not only exceptional performance on the printing press but also strict compliance with consumer safety standards. This webinar had highlighted practical solutions from Evonik to optimize ink spreading through innovative particles and surfactants tailored to specific applications.

Recorded Webinar: This webinar had introduced the know-how related the structure-property relationship of substrate wetting agents and their impact on the quality of the printed image as an integral part in enabling hight throughput digital printing.

It had explored regulatory trends and innovative digital solutions that address the increasing communication needs across the value chain.

Recorded Webinar: UV inkjet inks develop fast in recent years in the application of label, tobacco packaging and PCB etc. In this webinar we had shared our additive solutions for UV inkjet ink application, we had introduced our high performance dispersants for different type of pigments dispersing, surface control additives especially crosslinkable product series which can help to improve substrate wetting, slip property and scratch resistance etc, and our Co-binders which can help to boost the curing speed, improve adhesion and pigment wetting etc.

Recorded Webinar: Inks are often produced from semi-finished to address the application complexity and reduce the final production step to a blending operation. Semi-finished must not only be intermixable and compatible but also stable over the time. In this mini webinar series, challenges and solutions are presented. The first part presented solutions for pigment preparations and particle stabilization, so how to control the color and appearance of an ink. Part 2, will be related to foam, slip, release and substrate wetting - so control of the physical parameters of an ink.

Additionally, we have discussed the film formation process and common surface defects that can impact performance.

This webinar was part of the Surface Weeks.

The aspect of a coated surface is positively enhanced by the use of additives for surface control. Using the example of automotive coatings the different aspects of leveling, wetting and haptic effects has been shown on three substrates.

This webinar was part of the Surface Weeks.

Substrate wetting agents modify the static surface tension profile of fluids, thus impacting the rate of coverage and the final coverage ratio of the fluid. Process dynamics and the character of the surface being printed on call for quite a specific set of surface active wetting agents. To prevent the formulators from going through a pitfall of testing numerous substrate wetters, the selection had been narrowed down to a handful of additives to address the needs of all ink technologies met in the inkjet space, selected according to the most important criteria in the industry: functionality, health and safety, and compliance to relevant regulatory regulations.

Beside a basic introduction of automotive OEM coatings and certain coating layers, optimum products are recommended.
