Innovating to Meet Demand for Performance, Sustainability, Cost Reduction

THURSDAY, JUNE 13, 2019

Resins found in coating systems serve markets from hi-tech aerospace to residential design and everything in between. The chemistries behind these resins are equally as diverse. The opportunity and challenge for coatings manufacturers lie in harnessing and maximizing the strengths of the different chemistries to meet the growing demands of the marketplace.

As these markets evolve, there is consistent and clear demand for coatings that demonstrate better performance and increased sustainability while supporting cost-saving initiatives. This makes it essential for manufacturers to provide environmentally sustainable products with performance properties that exceed long-time standards and lower consumer costs.

To be viable in today’s coatings business, manufacturers must focus on continuous improvement, developing innovative solutions that meet the ever-demanding needs of their markets and position them to lead customers into the future.

Cost-in-Use Products: Doing More with Less


Direct-to-metal coatings are a useful tool in cost-saving initiatives.

As consumer demands grow, the emerging mantra in the coatings business is “Do more with less.” Consumers need increased performance at a lower cost.

For example, direct-to-metal (DTM) coatings replace traditional multiple-layer systems that include primers and topcoats with a single layer that provides the same function and performance. This means less product used, less time needed to apply it and less opportunity for application error.

The result is a cost savings without a decrease in performance. Ultimately, DTM coatings provide an efficient solution for savings in material, time and money.

BASF is addressing these needs through the development of additive technologies that complement resins by increasing formulation latitude and performance without sacrifice to sustainability or cost. Corrosion resistance, chemical resistance, long-term weatherability and adhesion to difficult substrates are all performance areas that are benefiting from these technologies.

BEST OF BOTH WORLDS: Solventborne Characteristics in a Waterborne System

JONCRYL OH 8314 is a waterborne system with solventborne characteristics.

One technology seeing growth in the coatings market combines high-performance waterborne resins with anticorrosive performance. Waterborne resins are considered more sustainable technologies, primarily because they have little-to-no VOC emissions. Low-VOC resins are not only wanted by consumers but specified in certain regulations.

To strike a balance between maximum performance and sustainability, BASF has developed a technology that combines the strengths of solventborne systems with the increased sustainability of waterborne technologies. One benefit of solventborne technologies that is typically missing in waterborne technologies is an indicator at the end of viable use through viscosity increase (pot-life indication). The pot-life indication ensures consistent performance and protects against application errors. Traditional waterborne, two-component polyurethane systems, compared to their solventborne counterparts, suffer from lack of an identifiable end-of-pot-life marker as well as reduced performance.

BASF has developed a solution to these challenges with the Joncryl OH 8314 waterborne system. It behaves like a solventborne system in which a viscosity increase serves as an easy indicator to stop application. The product is a hydroxyl functional epoxy/acrylic hybrid dispersion for two-component polyurethane coatings, utilizing a unique synthesis that produces performance and characteristics comparable to solventborne systems.

Coatings formulated with the product have exhibited good durability and feature a low-viscosity, low-isocyanate demand with excellent flow and leveling. Innovative processing provides a clean-water phase, which results in a surfactant-free, low-foaming and water-insensitive product with broad application utility, including DTM.

The product provides a new solution to the market need for waterborne systems that support sustainable initiatives, reduce the use of harsh solvents in equipment cleaning and reduce cost in use.
