Paint and Coating Resins & Polymers

RSS

As one of the world’s biggest polluters, the textiles industry needs an urgent sustainability transformation. To make circularity a reality, the coated textiles value chain needs to work together on end-to-end solutions – from more sustainable raw materials to textile recycling technologies.

Polycaprolactone (PCL) polyols can be used to enhance coatings that feature other polymer chemistries in both 1K and 2K coatings. This article explores the performance benefits achieved when low-molecular-weight PCL tri- and tetra-functional polyols are blended with other hydroxyl-functional polymers in 2K coatings.

Two of the more common 2K coatings systems are polyurethane and epoxy. This and next month’s Formulating with Mike column will concentrate on urethanes, with this issue focusing on polyurethane polymers. 

PCI’s “Did You Know” column has published a wealth of information about redox chemistries for use in emulsion polymerizations. This edition focuses on its use in aqueous-based polymer dispersions. 

This article examines the physical properties of polyurethanes and polyureas, their differences, and a technology review with benefits and drawbacks of sub-coating classes.

"We are proud to be a global leader in the energy curing industry," Wilfrid Gambade, iGM Resins CEO, said. "Our team will continue to focus on protecting our products and processes for our customers."

The coating and adhesive resins business line expects the additional production capacity to be ready as early as the second quarter of 2024, following the double-digit million-euro investment.

This month’s Formulating with Mike column continues the discussion on resins, with a focus on epoxy curing agents. When it comes to great adhesion, chemical resistance, and corrosion resistance, an epoxy is hard to beat. There are different epoxy curing agents, and each one provides different properties that can be suited for a wide variety of end-use applications. 

The recent Western Coatings Show in Las Vegas featured an exhibit hall packed with new technology for coatings formulators. This article offers a sampling of some of the raw materials and services showcased.

Through the incorporation of such unique benefits as leak-free operation and line-stripping capabilities, the eccentric-disc principle makes the pump extremely flexible, allowing the pumping of low-viscosity, high-viscosity, and highly abrasive materials within a single process — all with the same pump.
