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.

It is therefore important to evaluate different crosslinkers and understand their benefits and drawbacks in a given system to enable the formulation of a high-performance wood coating.

This study reviewed analysis of several formulations based on an FEVE emulsion and an FEVE dispersion.
