Paint and Coating Resins & Polymers

RSS

In this article, we report on the evaluation of microcapsule-based self-healing functionality in a range of organic zinc-rich primers with a view towards assessing potential synergies between the maintenance of the coating's adhesion to the substrate after damage afforded by the incorporation of the self-healing additive.

As a peelable resin for metal protection, this resin proves that it is possible to deliver a coating that provides the corrosion protection, scratch protection and chemical resistance of a paint, but with the easy removal of a peelable coating.

Salt spray corrosion resistance provided from powder coatings for ACE applications can be improved by new superdurable polyesters for ß-hydroxy-alkyl-amide, triglycidyl-isocyanurate and the blend of diglycidylterephthalate with triglycidyltrimellitate developed by Allnex.

Soybean oil, or its derivatives, primarily replaces petrochemicals, which often results in improved performance, lower VOCs, and in many cases a reduced economic cost.

Today, end users of smart coatings prefer those products that provide smart functionality, better weather resistance, high performance, improved productivity and increased service life of the component; reduce maintenance costs; along with ease of application and easy cleaning.

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.

Epoxy systems (resins) offer good adhesion, high mechanical and thermal properties, and good chemical resistance as industrial maintenance coatings.

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.

The unique hybrid chemistry of oxidizable phenolic urethanes combines the drying property of fast-drying oleoresinous vehicles, the chemical resistance of phenolics, and the toughness of urethanes.

Functional binders, when incorporated in low-VOC architectural coatings, offer a wide range of benefits in construction applications in terms of texture as well as durability.
