TEGO® Wet 288

In this webinar, we’ll explore how wetting additives helps to reduce surface tension and aids the wetting of a variety of different substrates. Different types of wetting agents will be introduced, which each provide a distinct profile. Recently the elimination of PFAS containing additives has created a lot of additional attention to this topic. We’ll also discuss how to make the right additive choice when recoatability or glueability is essential. Get a look at our latest developments, including TEGO® Wet 288.

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

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

This webcast shows you various factors that lead to blocking defects in printing inks, and more importantly demonstrate 3 different formulating approaches. Lab videos and pictures are illustrated to show you how additives could help you achieve flawless finish.

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.

This is an interactive video that showcase different service offerings to support printing inks customers thru innovations and efficiency. Come explore to take advantage of our competencies in regulatory guidance, sustainability, technical expertise and trainings.

Discover how innovative Evonik silica particles can enhance ink performance in our webinar.

Join us to learn how cutting-edge materials can boost the quality and efficiency of your applications.

The ability to effectively wet challenging surfaces has emerged as a significant hurdle in the formulation of inks and coatings. With the ongoing advancements in packaging materials, including low-density polyethylene, oriented polypropylene, metallic films, and aluminum foil, formulators face increasing complexities. Furthermore, evolving regulatory standards necessitate that products not only perform optimally during printing but also comply with consumer safety regulations. Additionally, issues related to hydrolytic stability of surfactants have led to variations in ink wetting properties over the product's shelf life.

In this presentation, an expert from Evonik had discussed the relationship between surface tension and substrate wetting, as well as the distinct roles of dynamic and static surface tension in both water-based and energy-cured systems. While a one-size-fits-all solution is not feasible, the diverse range of products offered by Evonik Coating Additives provides effective strategies to tackle these wetting challenges.

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: Siloxane-based additives show unique effects in waterborne, radiation-curing and also solventborne inks and varnishes. This webinar related structural motives to effects in inks and varnishes. It had displayed how to improve ink performance by the use of highly active siloxane-based additives, but also mentioned possible limitations. Can they potentially replace fluorosurfactants?

Recorded Webinar: Staying compliant with regulations is becoming more crucial than ever when it comes to creating new printing inks. This webinar is designed to offer advanced knowledge and comprehensive insights on key compliance matters.

Recorded Webinar: It is essential to have a basic understanding of regulations when creating a new printing ink. While the term "regulatory" may evoke negative connotations for some, this webinar aimed to provide fundamental knowledge on the topic in a relaxed manner.

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.

Keeping pace with product compliance in an increasingly complex regulatory environment is a challenge. In this webinar, we had summarized current changes and comprehensive insights on key compliance matters and sustainability topics. Digital tools were shown which help you to get the updated data you need.

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.
