Faster curing agents for rapid return to service     

Wet-on-Wet epoxy coating refers to a method of applying an epoxy coating where additional coats are applied before the previous coats have cured. Epoxy systems can be used as primer or as an intermediate coat. The functional primer coat provides corrosion and barrier protection to the steel and facilitates the intercoat adhesion of subsequent intermediate coat. It is essential that epoxy primer develop its functional properties like hardness, cross link density, Glass transition temperature (Tg) and provide sufficient recoat window for the intermediate layer. The recent and trends and drivers in epoxy coatings market suggests that unique characteristics of epoxy curing agents can be capitalized by significantly lowering the cure time thus enhancing the productivity and throughput in both factory and field applied epoxy systems. In this presentation we demonstrate the performance attributes of a novel polycyclic-aliphatic amine accelerator which can provide rapid through cure and enables wet-on-wet epoxy applications. Glass transition (Tg), IR cure profile, Intercoat adhesion, corrosion resistance, data will be presented.

New Waterborne Systems Bring Fast Return-to-Service and Excellent Aesthetics

Coating industry is constantly facing the challenges of meeting more stringent low emission requirement and fulfilling the need to improve productivity and reduce costs while maintaining high coating performance. Technology advancements equipped the industry with new waterborne epoxy systems that deliver fast cure speed, improved coating robustness and better aesthetics over the service life. Thanks to the low volatile organic content (VOC) and excellent coating properties, waterborne epoxy coatings have become a commercially important technology and gained wide acceptance as environmentally friendly alternatives for solvent borne and solvent free epoxy systems The paper will highlight the development of a new waterborne epoxy curing agent based on novel amine technology. The product provides an extremely fast cure speed even under the adverse condition such as low temperature and high humidity, and superior adhesion to substrates when used as a primer, in particularly on damp concrete. When used as a topcoat it provides an excellent surface aesthetics. This enables coating formulators to design new coating concepts, such as a 1-day floor system, consisting of a primer and topcoat that could be applied on the same day and deliver walk-on readiness the next morning. The paper will discuss model formulations based on the new curing agent, key features and benefits of the new waterborne system.

Polyamine Curing Agents Meeting the Industry Need for Enhanced Productivity

In the challenging world of industrial, protective and marine coatings, two component epoxy systems are established as the benchmark technologies due to the combined offerings of excellent corrosion protection while being compliant with regional VOC standards. Today, productivity has emerged as a major driver and innovation focuses on developing epoxy coatings that have greater application versatility while providing enhanced performance properties, such as dry speed, rapid recoat and through cure. For Marine and Protective, the need is for faster cure and blush resistant coatings when applied under adverse, low temperatures conditions. In the OEM sector, the wet on wet application process means there is a requirement for epoxy systems to provide rapid overcoatability with polyurethane and/or polycarbamide topcoats within minutes after initial application of the primer. In the OEM sector, the drivers are to increase overall productivity with faster application of multiple layers coupled with lower bake temperatures, which can provide energy savings. This paper will focus on the performance attributes of a novel polycyclic- aliphatic amine and its use in the development of new epoxy curing agents designed to provide benefit in the above markets. The supporting data includes the functional properties; thermal analysis, glass transition (Tg), IR cure profile, confirming the rapid through cure and cross-linking capabilities in epoxy systems. In addition, a review of model coating formulations and their key performance attributes, including the rapid recoat times, improved intercoat adhesion, excellent corrosion protection properties will be discussed.

Silyl-Polyurethane Crosslinkers for Ambient Cure Topcoats with Fast Return-to-Service Times 

Two-component polyurethanes are the performance benchmark of the coating industry for weather-stable, chemically resistant topcoats. While their performances are difficult to surpass, their return to service times can require a full day at ambient temperatures and the handling of isocyanates requires careful regard to PPE. Evonik has developed silyl-polyurethane (NISO) technology that exceeds performance of 2K polyurethanes with regard to scratch resistance and anti-graffiti characteristics and can be formulated both as 1K and in 2K coatings with hydroxyl-functional polyols. This presentation will show new binder systems developed in the last two years that have superior performances compared to 2K polyurethanes and dry-through times within two hours.

Win The Race, Ultra-Fast Curing Agents for One Day Flooring 

In concrete coatings and flooring systems, a rapid return to service is a highly desired attribute, but remains elusive without negatively impacting other performance characteristics. Delivering the speed while maintaining a balance of good handling properties in conjunction with quality physical properties has been the subject of significant R&D over the past several decades by coating manufacturers and raw material suppliers.
The main objective of this presentation will be to illustrate how it is possible to achieve these highly desirable attributes through a combination of advanced thermoset technologies (epoxy and polycarbamide/polyaspartic). The thermoset resin technology covered within the scope of this presentation consists of waterborne or high solids epoxy technologies for primer/basecoat applications used in conjunction with polycarbamide technology for topcoats. By leveraging the unique attributes of these technologies, flooring systems with low VOCs, good UV resistance, rapid hardness development, and good physical and mechanical properties are attainable.


We are looking forward to share our knowledge with you!
