The presence of moisture in concrete can be attributed to several factors, including trapped moisture, saturated sub-base soil, groundwater, and inadequate drainage. Moisture vapor permeates concrete slabs due to capillary pressure and temperature or pressure gradients between warm and cool surfaces.

This migration of moisture vapor can lead to floor failures, such as osmotic blistering, delamination, and damp flooring, resulting in significant annual repair and liability costs.

Preventing adhesive failure on concrete floors primarily involves minimizing moisture vapor transmission to an extremely low level. This can be achieved by applying a resin-rich barrier coating layer. Two-component epoxy coatings are commonly used for this purpose due to their strong adhesion to concrete and low moisture vapor transmission characteristics. However, they typically require the addition of plasticizers to achieve a high degree of conversion and complete property development. Our recent innovative technology provides a solution to reduce or eliminate the reliance on commonly used plasticizers, resulting in lower emissions while maintaining a high degree of curing.

This webinar will center on the development, advantages, and model formulations of our low-emission amine curing agent technology, which facilitates the creation of various systems with exceptional moisture vapor barrier properties in thin coatings. This new technology offers rapid property development and customizable curing rates and working times. The combination of low emissions and adjustable handling properties provides coating formulators with options to design new floor systems featuring ultra-thin coatings with moisture vapor barrier protection.

To the recording

Epoxy based paints are very well-established coating systems for metal protection in marine and protective applications. However, epoxy coating industry is faced with the constant challenge of providing solutions which can comply with emerging VOC regulations. To meet these challenges, the content of solvents and plasticizes in a paint formulation is reduced as much as possible.

These high solid formulations experience difficulties in offering good balance of pot-life, dry time, viscosity and flexibility. While, the use of plasticizers which slowly leach out of coatings can cause the coating to decrease in flexibility over time, thus changing the performance properties of the coating.

In order to overcome those challenges, Evonik developed new amine curing agent technology, which allows to design ultra-low emission epoxy paints without compromising in handling or performance properties of traditional solvent born systems. Smart designed new curing agents exhibit low viscosity and build up properties very fast at ambient and low temperature. It needs little or no plasticizer for full cure, so that the coating is more likely to maintain their performance throughout their service life. At the same time, it yields high barrier properties, excellent flexibility and very good adhesion on metal.

In scope of this webinar we will demonstrate the handling and performance attributes of a novel amine curing agent technology which can provide solutions to develop ultra-low emission epoxy paints with sustainable high performance.

With our brand-new VESTA eCO grades we’ve swapped virgin fossil raw materials for renewable ones to make your solvent, composite and coating systems much more sustainable.

As the pioneer in isophorone chemistry Evonik is currently the only company in the world offering a renewable I-Chain platform that includes isophorone, -diamine and -diisocyanate products.

During this webinar we’ll discuss our VESTA eCO product series and why there is no compromise in performance compared to virgin fossil-based grades. We will also explain what kind of renewable feedstocks we use and how the certified mass balance approach works so you can start passing these C02 emissions savings on to your customers.

Discover how we can help you to reach your sustainability goals.

Of all the current environmental, social and economic challenges, sustainability has emerged as one of the most important, but also one of the most complex drivers for the chemical industry. For Evonik as one of the leading specialty chemical companies in the world sustainability has become a central element in its purpose, “Leading Beyond Chemistry” to provide solutions that help to make everybody’s lives more sustainable, healthier and comfortable.

Positioned in the middle of many value chains Evonik is a solutions provider enabling others to achieve their sustainability objectives. With a versatile portfolio of epoxy curing agents, we not only support our customers in the development and production of structural adhesives with high performance and reliability, but also contribute to their sustainability.

In this regard, we offer a range of solutions within our portfolio that address many different sustainability aspects, including epoxy curing agents based on renewable raw materials, helping to improve the sustainability of processes and enabling sustainable technologies. Hence, the focus of this webinar will be on our different approaches to improving sustainability in the field of epoxy-based structural adhesives and will include a short outline of Evonik’s general sustainability strategy.

Maximizing productivity and enhancing performance are key drivers in concrete floor coatings. Even better is if such a coating meets the low emission requirement . In a typical two-coat floor system, cure speed of the primer is critical for applicators who want to apply both a primer and topcoat in the same work day. It is equally important, if not even more, to job specifiers or end-users who demand minimum downtime.

With the above drivers in mind, Anquamine® 728 a waterborne curing agent was developed to deliver exactly that: a primer with a recoat time less than four hours at 10 °C (50 °F); excellent adhesion to concrete, high aesthetics, and potential to meet low emission requirements. It is easy to install. In addition, Anquamine® 728 based coatings can be applied up to 20 mils (500 g/m2) wet film thickness without compromising cure speed. It provides fast cure speed under high humidity up to 85%. Anquamine® 728 is versatile: it can be used with both liquid epoxy resin and solid resin dispersion, formulated into 2K or 3K systems, in clear or pigmented coatings.

This webinar will introduce a portfolio of waterborne epoxy floor systems used in a wide range of applications with an emphasis on Anquamine® 728. The webinar will demonstrate the performance advantages of Anquamine® 728 and how it can be used to formulate a one-day floor system, and get business back in service fast.
