Ashland is transforming its technical and analytical services for the paint and coatings industry by adding a dedicated laboratory to its campus in Wilmington, DE.
During the annual R&D 100 Awards event held on November 12 and 13, R&D Magazine honored Dow Coating Materials (DCM), a business unit of The Dow Chemical Co., with an R&D 100 Award.
The new rheological additive (RA) produces strong initial anti-sag results, even under these very low-energy mixing conditions with no added heat. The stability following accelerated aging is also greatly improved relative to the commercial RAs. The new RA activates quickly and does not require a lengthy heat up period during paint or adhesive manufacturing.
These suppliers share their perspectives on the current market, industry drivers, steps they take when developing new products and challenges that formulators face.
Excellent clarity through control of the particle size and balance of flow and leveling through thixotropic behavior can be achieved with these rheology control agents.
Additives belong to a broad and diffuse category of key components in a coating formulation. The following is a brief description of many coating additives, along with some examples.
Part one of this article discusses the theory of optimizing applied hiding and new techniques used to characterize applied paint films to determine the influence of rheology on application.
