It is up to the creative minds of the industry to make use of polysulfide polymer self-healing properties to create uncontested market environments for polysulfide-based sealants, adhesives and coatings, and priceless added value to their customers.

This article provides further insight in how PLA polyols expand the formulator'’s toolbox for the development of coatings with improved key properties such as hardness, adhesion, solvent resistance and fracture toughness.

In this work, mini-emulsion polymerization was used to prepare formulations containing various sizes of ZnO nanoparticles in order to increase photostabilization of exterior clear coatings for wood.

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.

WACKER has developed a dispersible polymer powder that allows manufacturers to formulate interior wall paints in powder form. The technology does not require the addition of biocides and offers key advantages when it comes to storing and transporting paints.

Sustainability has been a hot topic for many years, but it seems to be experiencing a resurgence in recent months. PCI recently reached out to Helen Mets, President DSM Resins & Functional Materials, to get her thoughts on the topic.

In this experiment, NaSS showed the best performance in terms of mechanical stability, foaming and water absorption. This was attributed to the good polymerizability and surface activity of NaSS. But there is still room for improvement, especially water resistance.

Because of their versatility, methylene malonate monomers have shown potential in a wide variety of applications, such as one- and two-component clear coatings for automotive and industrial use, adhesives for packaging and industrial use, waterborne coatings and adhesives, pressure-sensitive adhesives, encapsulated pigments, and composite binders.

In this article, we discuss the design of self-healing functionality into silicone-based protective materials to improve their ability to maintain adhesion after damage.
