Printed in Paints & Coatings Industry (PCI) Magazine and shared with permission. Epoxy powder coatings are known for their excellent protective characteristics in applications such as pipeline coatings, electrical insulation coatings, appliance primers, automotive parts, and rebar coatings. The high crosslink density of epoxies is a double-edged sword, as it imparts high resistance to corrosion and chemicals, but also tends to make the coating somewhat brittle and susceptible to damage, for instance during pipe installation. The use of Hypro® reactive liquid polymers is demonstrated to help correct this and dramatically improve the overall durability and flexibility of coatings.
