Paint and Coatings Additives

RSS

Whether decorative paints or industrial coatings, waterborne finishes need a perfect surface appearance and optimal mechanical properties. Leveling and substrate wetting agents can be a valuable aid for this purpose.

The article also addresses a specific limitation (tint viscosity retention) that occurs with NISATs, and how next generation tint viscosity stabilizers help alleviate this concern.

A modular chemistry platform has been successfully leveraged to generate a new class of high-performance polymeric pigment dispersants.

Additives are used in small quantities and can have the highest per unit cost of coatings raw materials. They facilitate production, or improve certain properties of the wet coating or the final film. Learn about rheology modifiers and suspension agents in Part 1 of this four-part series.

A new difunctional water-based crosslinker is used to crosslink acid or carboxyl functional coatings, inks and adhesives to increase adhesion, physical and chemical properties.

Recent research conducted at Iowa State University has developed an innovative coating additive made from amphiphilic Janus particles that can alter the surface properties of a waterborne coating system.

Branched surfactants show promising results as an effective replacement for APEs in white architectural paints and tinting systems.

The post-addition of different grades of fibrillated HDPE fiber has shown to positively affect film formation, tensile properties and wet track abrasion resistance of a commercially available asphalt emulsion driveway sealer/coating.

Unexpected failures may appear after paint application, drying and aging. Surfactant leaching is one such failure, and is discussed in detail in this article.

This work deals with the assessment of fungal deterioration on different anti-corrosive coatings using electrochemical techniques (corrosion potential and ionic resistance).
