What is a Polyolefin Coating?

A Polyolefin Coating is a type of coating that is applied to a surface in order to protect it. This coating is typically applied to surfaces that are subject to wear and tear, such as floors and countertops. Another large application is in the field of industrial infrastructure. Polyolefin coatings are also used in a […]

What is the difference between shielding and non shielding pipeline coating failure?


The European Pipeline Research Group outlines that steel pipelines are best defended against external corrosion through a protective coating in addition to cathodic protection. The coating offers the initial—and primary—source of defense, while cathodic protection halts pitting or general corrosion where the pipe is exposed via damage to the coating. Its important to note that […]

Coating Composition and Properties

An understanding of the process is required to develop a coating is useful when considering the composition and properties of any coating. The following explanation is from the viewpoint of the coatings development chemist. It is a consideration of the types of basic raw materials available, required properties, formulation variables and finally, coatings performance.  Definition […]

Zinc Filled Coatings

What is a Zinc Filled Coating? The corrosion of steel or iron is an electrochemical phenomenon wherein the base metal reverses to a lower, more stable more energy state.  If the corrosive environment is water or brine, then the coating product formed is commonly known as rust.  In the case of other chemicals, such as […]

Generic Types of Atmospheric Coatings

Industrial paints and coatings are usually categorized by the major resin contained in the product.  We categorize paints and coatings so we will have some idea of what to expect when a coating is specified, applied, or repaired.  In general, the predominant physical characteristics and chemical resistance of a coating are determined by that resin […]

The development of Surface Tolerant Coatings

What is Surface Tolerant Epoxy Coating?  The history of Surface Tolerant Epoxy Coating The 1960’s and early 70’s In the 1960’s and early 1970’s, the predominant heavy duty protective coating system was inorganic zinc silicate primer with an epoxy topcoat.  Some well-known characteristics of zinc rich primers were that they were ideally suited to the […]

Thermoset vs.Thermoplastic Coatings

What is the difference between Thermosetting and Thermoplastic Coatings? Thermoset coatings are those that are applied in a liquid state and cure, in place, by means of a chemical reaction thereby becoming insoluble in solvents.  The chemical reaction, or crosslinking, converts lower molecular weight materials (small molecules) into high molecular weight materials (large molecules or […]

What is visco-elasticity?

This is a set of particles that due to their shape can temporarily connect to each other which causes elastic properties, and due to their flexibility, can easily slide along each other which causes the fluid properties. From our high-school lessons in physics, we learn that molecules are in a state that is considereds either […]

What is a visco-elastic coating?

The main characteristic of this coating material is the permanent visco-elastic behaviour. In other words it will stay in a high viscous fluid phase even after years of application. Due to this visco-elastic property, the system is able to self-healing small coating defects. Usually the basic raw material for a visco elastic coating is “PIB” […]

What are manufacturers of visco-elastic coatings (PIB)

SEAL FOR LIFE INDUSTRIES STOPAQ® The original inventor of visco elastic coatings based on polyisobutylene was the Dutch company called Frans Nooren Afdichtingssystemen BV, that later became famous as a company called STOPAQ® . It was around the 1980s, when the innovation driven Frans Nooren grew to be an expert in watertight sealing systems. At […]
