In this study, polyurethane-acrylic resins with UV functionality have been evaluated according to industry specifications for both interior and exterior industrial wood applications.
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.
