Additives for the Coatings Industry | CoatingPaint.com
Coating additives enhance and improve coating quality. At its most simplified, a paint or coating is the combination of a pigment, a binder (or resin), and optionally, a solvent and additives.The pigment is the substance which provides the coating with its color, the binder provides both adhesion and cohesion, holding the paint together as well as binding it to the substrate, finally, the

Specially formulated for aqueous fluoropolymer coatings, NANOMYTE ® PC-10 is easily incorporated into commercial coating formulations for thermoset coatings (e.g., polyurethane, nitrocellulose and epoxy) to improve abrasion resistance and scratch resistance. Even just small additions of PC-10 leads to a dramatic improvement in desirable mechanical properties (up to 50%) without affecting the
Improvement of Flowability of Fine Cohesive Powders
In recent decades, one of the most frequently used solutions to this problem has been to add small amounts of flow additives that improve the flowability of these fine cohesive powders. This paper provides an overview of the physico‐chemically active principles of flow additives, model approaches and useful flowability evaluation methods.
Powder Handling: Make the Most of Flow Additives
Indeed, making the optimum choice requires fully determining how an additive will affect the manufacturing process and influence critical quality attributes of the final product. While most flow additives are selected on the basis of their ability to improve flow, the question remains as to what constitutes "improved flow" in a given process.
Additives for Coatings | Wiley Online Books
Additives are the key to success in achieving these characteristics, even though the amounts used in coating formulations are small. It is not trivial at all to select the best additives. In practice, many series of tests are often necessary, and the results do not explain, why a certain additive improves the quality of a coating and another
Additives - Coatings World
Additives - There are a wide variety of additives that are incorporated into paint formulations to alleviate or eliminate problems that can arise, improve product quality, or prevent problems from occurring during manufacture, storage, or application. Some of the many types of additives include: adhesion promoters; antiblocking agents; anti-foams; anti-freezes; antioxidants; antifouling agents
Improved surface of additive manufactured products by coating
The additive manufactured coated sand products had obvious staircases on the surface and lots of small holes inside. The alcohol based refractory coating and the water based refractory coating were applied to improve the surface of the samples. The polygonal samples were used to check the effects of the coatings on reducing the surface roughness.
