Despite the challenges of reformulating a coating from solvent‐based to waterborne and curing a low-molecularweight EPDM at ambient temperature, formulations have been successfully developed utilizing peroxide, oxidative and UV-curing systems.

New waterborne epoxy resins and amine curing agents offer traditional epoxy performance while meeting the market’s desire for higher performance, lower cost and lower solvent content.

Newer polymeric dispersants, which represent improved alternatives to the more traditional anionic dispersants, enable formulators to achieve good stability and color properties for dispersed pigments in waterborne paint systems.

Despite the differences in film formation, novel technology in polymers for water-based sealers gives an improved balance of properties that is commercially acceptable for today’s concrete sealers. The new type of polymer is compared to conventional concrete sealers for key performance properties.

A double first has been landed by AkzoNobel's Aerospace Coatings business after it supplied products for a new long-distance tanker aircraft commissioned by the French Air Force.

In recent years, the focus has been on the development of durable and sustainable coatings, looking for solutions that would support the transition from fossil to bio-based products with equivalent performance.

The introduction of energy-curable polyurethane dispersions (UV PUDs) to complement the traditional radiation curing technology profoundly changed the market landscape by bringing coating performance and sustainability to the next level of requirements.

Maxemul reactive surfactants act as efficient emulsifiers providing colloidal stability and are chemically bonded to the polymer particles during free radical polymerization. The enhanced stability and mitigation of surfactant leaching during and after film forming significantly improve water resistance and barrier properties of the latex binder as a replacement of conventional surfactants.

This article is a comparison study using an accelerated weathering method to test different wood types pretreated with and without Eversorb SB in different co-solvents.

As demonstrated by the real-world exposures presented in this article, use of a primer is very beneficial over even the most challenging substrates. In some cases, the lifetime of the topcoat can be extended by over three years when a primer is used.
