The Science

Read below for an insight into the science behind the coatings produced by Coating Kings

Covalent Bonding

Covalent Bonding

The interatomic linkage that results from the sharing of an electron pair between two atoms. The binding arises from the electrostatic attraction of their nuclei for the same electrons. This means that the molecules that make up our coating are chemically reacting (bonding) with the surface molecules they come into contact with. A covalent bond is the most durable and strong bond. When a covalent bond happens, a form of new surface is created. Our coatings covalently bond with the surface that they treat, making very difficult for the coating to be removed from the surface.

Bond Dissociation Energy

Bond dissociation energy is the energy required to break a bond and form two atomic or molecular fragments, each with one electron of the original shared pair. A very stable bond has a large bond dissociation energy—more energy must be added to break the bond. In the case of the range of coatings from Coating Kings, they all have a very strong covalent bond and therefore have a very high bond dissociation energy.

Surface Energy

In simple terms, surface tension is what determines whether a liquid beads on a surface (hydrophobic and / or oleophobic) or sheets on a surface (hydrophilic / oleophilic). When a droplet forms a bead, cohesive forces are at play meaning the molecule would rather bond to itself than it would the surface. When liquid sits flat on a surface then adhesion is at play and the liquid would rather bond with the surface than itself. Once a surface is coated we then talk about surface energy. What Coating Kings aims to do with its coatings it to create a surface energy that is lower than both that of oil and water meaning that it becomes hydrophobic and oleophobic allowing for the easy clean of water based and oil based substances from surfaces.
