TYPES OF EPOXY COATINGS AND THEIR IMPORTANT FEATURES

The use of epoxy coating in residential, commercial, institutional and industrial arenas and transportation facilities is not new at all.

In fact, this coating has been found very frequently even in marine applications and in all these areas; they are used for giving an entirely transformed appearance to the area.

The companies involved in rendering these services use different solutions and agents to perform this task of epoxy coating.

This means that these companies can perform different kinds of epoxy coatings and it is the responsibility of the client to choose the best one.

However, the experts from companies that offer these services will help you by making you familiar with different kinds of epoxy coatings by defining them before you.

Some top types have been discussed here in this post.

Polyamide EpoxiesAccording to the experts of epoxy resin coatings Sydney, this type of coating is used as a curing agent and in this type, some very popular reactive polyamide resins are combined to compile a robust solution.

The best feature of these reactive polyamides is that they are actually the outcome of long fatty acid dimmers that react with multi-functional amines.

These amines are general terminal amines and they have really great molecular distance between them and this actually reduces the overall vapour pressure of the resin.

Another important thing to know about this version is that these epoxy coatings are used in primers for reliability, flexibility, adhesion, better wetting characteristics and enhance corrosion resistance.

This means that as compared to others, this kind of epoxy coating would stay more resistant to moisture, water and alkali conditions.

However, the drawback associated with this type of epoxy coating is that it has a really poor chalk resistance and only moderate resistance to acid.

Polyamine Epoxies: The next type of epoxy coating is given the name of polyamine epoxies and this type is generally used to firm hardness, abrasion resistance as well as chemical resistance.

In this regards, one thing that needs a mention here is that there are different types of amine categories present and the top names are aliphatic

amines, cycloaliphatic amines, aromatic amines, ketamine, and phenalkamines.

An interesting fact to know regarding these amines is that they can offer a wide range of chemical resistance related characteristics to the main epoxy coatings.

For example – there are polyamine epoxies that provide improved resistance to microbiologically induced corrosion.

However, remember that these polyamine epoxies are characterised by a shorter pot life and recoat windows as well.

Then, the top features are the chemical resistance and heat resistance and the main difference with this one and the one discussed above is that polyamide cured epoxies provide better flexibility, better abrasion resistance, improved corrosion resistance, etc.

On the other hand, there are polyamine epoxy coatings that are tough, more chemical resistant, brittle, and provide improved abrasion resistance.

There are two other types of epoxy coatings as well and a brief of both of them is presented underneath.

Phenolic Epoxies – These formulations is used for high chemically-resistant can and drum liners.

Novolac Epoxies – They are used in applications where there is a need for higher chemical and/or higher temperature resistance.
