This article describes an alkali copper aluminoborophosphosilicate glass ceramic material that acts as a sustainable delivery system for Cu+1 ions with high antimicrobial efficacy.

With RHEOBYK-7610, BYK has succeeded in developing a rheology additive which, in addition to the familiar properties, generates a specific viscosity profile.

The use of barites is a proven method for accurate control of gloss in the high- to medium-gloss range. ATH is the product of choice for gloss control when the relatively high density of barite is undesired, or in applications where improved resistance to water spotting is an issue.

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.
