Chinese Government Regulations Driving Adoption of Low-VOC Coatings

Perspective view of building in downtown hong kong city with light at night time.
Concerns over pollution in China have been increasing over the past decade. Significant attention to the problem was raised during the 2008 summer Olympics, which were held in the country. In response, the Chinese government in recent years has passed legislation mandating the reduction of volatile organic compound (VOC) emissions from manufacturing plants, including those that produce and those that...

Improved Durability through Reactive Dispersant Technology

Pouring red paint
Even though formulation additives comprise only a minor part of a coating formulation, they can have pronounced effects on the physical properties of the final coating. This is especially true for pigment dispersants, which can enter a coating formulation “under the radar” through, for example, pigment pastes.  As dispersants are often polar polymers with a low glass transition temperature, the...

Balancing Performance of Slip/Mar Additives Using a High Throughput Approach

Luxury modern white kitchen
Additives formulating can be resource intensive and time consuming to paint manufacturers due to the plethora of ingredient combinations and interactions that affect performance properties.  These challenges may inhibit the efficacy of selected additives, which are particularly important in low-VOC formulations to address foam control, water sensitivity, and general surface properties.  Silicone additives in particular are disproportionately influential in impacting...

The Demand for Coatings Raw Materials to 2022

Explosion of colorful powder, isolated on black background
Raw materials, in the form of individual chemical constituents that are incorporated into paints and coatings, represent an exceptionally diverse and vitally important sub-set of the overall specialty chemicals industry. They may either be added to a paint or coatings formulation during the product manufacturing process—or, in the case of multiple-component coatings systems (2K, 3K, etc.)—may be used to make...

Proteins and Peptides as Replacements for Traditional Organic Preservatives: Part I

Protein molecules
The utility of a high-throughput, spectrophotometric assay in screening over 23 enzyme and peptide-based additives against bacterial coating spoilage agents was evaluated. Candidate additives were then evaluated using ASTM D2574 for in-can coating spoilage challenges, and additives that may be used to substitute for traditional biocides were identified that eliminated recoverable bacterial growth.
