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"

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 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.

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.

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.

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.

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

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: Evonik coating additive portfolio for high solid, ultra high solid and solvent-free systems.

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.

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: Printing processes are getting faster and faster, substrates more and more diverse and global regulatory requirements more and more stringent. In this webinar, you will learn how Coating Additives copes with these requirements and proactively builds a portfolio of suitable high performance additives. Trends, star products and latest developments has been discussed along with practical examples and recommendations.

Recorded Webinar: Coating defects can cause severe headaches in wood coating applications. We have several options of additives in our portfolio to get rid of these defects or solve challenges like wetting of difficult substrates easily. In this webinar we had provided you with recommendations for water based, solvent based & UV coatings.

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.

Recorded webinar: This recorded webinar presents Evonik’s special silica products and explains the main benefits of each product in waterborne matt coating systems.  The webinar covers fumed silica, matting agent and spherical silica products.

Recorded Webinar: This webinar focuses on solutions to eliminate reaction foam in WB 2K PU systems. It also covers the topic of matting of waterbased wood coatings.

Recorded Webinar: Fluorosurfactants are well established in the wood coatings world, but are facing increased regulatory challenges. This webinar highlighted future proof additive alternatives without compromising technical properties.

Recorded Webinar: The Importance of Sustainable Solutions: Defoaming, Anti-Corrosion, and Anti-Fouling effect for Marine & Protective Coatings. During this live webinar we had focused on various sustainable topics for Marine & Protective Coatings.  

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.
