What is the application of calcium carbonate in paints?

Calcium carbonate

Calcium carbonate is a non-toxic, odorless, non-irritating white powder and one of the most versatile inorganic fillers. Calcium carbonate is neutral, substantially insoluble in water and soluble in acid. According to different calcium carbonate production methods, calcium carbonate can be divided into heavy calcium carbonate and light carbon. Calcium acid, colloidal calcium carbonate and crystalline calcium carbonate. Calcium carbonate is a common substance on the earth. It is found in rocks such as vermiculite, calcite, chalk, limestone, marble, travertine, etc.Read More …

What are the hazards of powder coatings?

powder coating spray

Most powder coating resins are less toxic, and the curing agent is significantly more toxic than the resin. However, when formulated into a powder coating, the toxicity of the curing agent becomes very small or almost non-toxic. Animal experiments have shown that there is no death and injury symptoms after inhalation of the powder coating, but there are different degrees of irritation to the eyes and skin. Although general powder coatings have no obvious harm to the human body, theyRead More …

Cleaning functions most importantly in maximizing powder coating results

cleaning sandblast

The highest quality powder coating will provide excellent results only if the pretreatment (cleaning, phosphatizing, conversion coating) is done correctly and the overall pretreatment system is maintained up to its potential. Powder coating brings pretreatment back to the basics of cleaning, rinsing, phosphatizing,and seal rinsing. To maximize the benefit derived from powder, the pretreatment system must provide a clean conversion coated product in a dry state to the powder booth. Surface preparation encompasses more than conditioning or improving a substrateRead More …

Economic advantages of powder coatings

powder coating spray

Energy and labor cost reduction, high operating efficiencies, and environmental safety are advantages of powder coating that attract more and more finishers. Great cost savings can be found in each of these areas. When compared with a liquid coating system, a powder coating system has several obvious significant economic advantages. There are also many advantages that may not appear significant by themselves but, when collectively considered, contribute substantial cost savings. Although this chapter will try to cover all cost advantagesRead More …

Advantages of Epoxy Polyester Hybrids

Smart Coatings market

Epoxy powder coatings based on newer technology are known as epoxy-polyester “hybrids” or “multipolymer” systems. This group of powder coatings could be considered simply part of the epoxy family, except that the high percentage of polyester utilized (often more than half the resin) makes that classification misleading. The properties of these hybrid coatings are more closely akin to epoxies than polyesters, with a few notable exceptions. They show similar flexibility in terms of impact and bend resistance, but produce slightlyRead More …

Four Basic Pieces of Equipment for Electrostatic Spray Systems

Most electrostatic powder spray coating systems are comprised of four basic pieces of equipment – the feed hopper, electrostatic powder spray gun, electrostatic power source, and powder recovery unit. A discussion of each piece, its interactions with other components, and the various styles available is necessary to understand the functional operation of this process. Powder is supplied to the spray gun from the powder feeder unit. Usually powder material stored in this unit is either fluidized or gravity-fed to aRead More …

Methods of Applying Powder – ELECTROSTATIC SPRAYING

Electrostatic Spray-Corona Powder Coating

Electrostatic spraying is the most widely used method of applying powder coating materials. Its growth is increasing at an impressive rate. Developed in the mid 60’s , this process is the most efficient means of applying coatings and finishes in a short time. However, acceptance of powder coating in general was initially very slow in the US. In Europe, the electrostatic powder spray concept was accepted more readily, and the technology moved much faster there than else-where in the world.Read More …

A summary of the key properties of each generic type of thermosetting powder coating

Industrial finishes are custom formulated to individual and end-user requirements. Successful selection depends on a close working relationship between users and suppliers. Selection should be strictly on a demonstrated film performance basis. This is because the film performance of a thermosetting powder coating is completely dependent on the bake it receives in a particular plant, on a particular substrate, with a particular degree of cleanliness, and type of metal pretreatment. Many specialties in the marketplace can cross over the guidelines.Read More …

Typical examples of thermoplastic powder coatings

thermoplastic powder coatings

A thermoplastic powder coating melts and flows on the application of heat, but continues to have the same chemical composition when it solidifies on cooling. Thermoplastic powder coatings are based on thermoplastic resins of high molecular weight. The properties of these coatings depend on the basic properties of the resin. These tough and resistant resins tend to be difficult, as well as expensive, to be ground into the very fine particles necessary for the spray application and fusing of thinRead More …
