Paint and Coatings Additives

RSS

Specialty chemicals are used throughout many industries, including coatings. PCI recently asked Jonathan Craig, Vice President Specialty Chemicals at Ascend Performance Materials, to discuss these performance products and the current state of the market.

These new dispersion additives provide excellent outdoor protection for all water-based polymeric binders used in exterior applications such as coatings, grouts and plasters.

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.

Green building is rapidly starting to scale up, bringing to light emerging issues such as the nexus between sustainable building design and fire safety - a challenge addressed by Perstorp's bio-based pentaerythritol for intumescent coatings.

Newer polymeric dispersants, which represent improved alternatives to the more traditional anionic dispersants, enable formulators to achieve good stability and color properties for dispersed pigments in waterborne paint systems.

With multiple major coatings suppliers now turning to Selektope to enhance the hard fouling prevention offered by their anti-fouling products, ship owners are encouraged to check whether this unique active agent is present in the anti-fouling systems being considered during their coating selection process.

It is essential to use an anti-foaming agent that allows optimal control of foam formation during production stages and keeps its properties during storage.

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.

By employing a bottom-up approach that includes the appropriate choice of wax chemistry (and therefore target physical properties), consideration of the migration ability of the wax (usually related to particle density), and proper testing to prove important surface properties such as scratch resistance, one can indeed successfully use waxes for cost efficiency and targeted performance in coatings.

The global coatings additives market is witnessing increasing demand from various industries. Coatings additives are a specialized group of chemically engineered materials that find application in a number of industries. They impart excellent chemical properties to the formulation, including improved wettability, dispersion, rheology, UV protection, chemical resistance and high-temperature stability.
