In less than 7 minutes we would like to tell you about our latest investment for Inkjet applications, what it can do for us and what we could do for you. 
Belief in the potential that inkjet represents for the printing industry is reflected in our continued efforts to provide our customers with specific recommendations, custom solutions and even specifically developed products. Find out more about the technical capabilities of our drop watcher and print station, and about modes of collaboration we offer that may assist you on your path of developing inkjet inks.

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.

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: We discuss different defects generally happening in Automotive application layer wise and suggest our CAD additives to rectify those defects.

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: 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.

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.
