PFAS here. . .PFAS there. . .PFAS is everywhere we turn in the first few months of 2024. A buzzword in the global specialty chemicals industry, PFAS producers and users need to bring their finest and most dedicated R&D efforts to bear on various regulatory and sustainability issues if we are to move technology forward, not backward.

Covestro has introduced a waterborne and waterborne-UV family of high-performing resins for industrial coating applications such as wood furniture, cabinetry, and building products.  

Two of the more common 2K coatings systems are polyurethane and epoxy. Part two of this series concentrates on urethanes and 100%-solids systems. 

Nanotechnology is an emerging field that is enabling breakthroughs of new and effective tools in the coatings industry. The trends and developments mentioned in this article are a few hot bets expected to impact the coatings industry in the coming years.

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."
