What is coal tar epoxy used for?
Coal tar epoxy is a black surface protection polymer for use on extremely corrosive environment surfaces. It is simply a blend of various epoxy resins and coal tar. Many commonly use the epoxy to make high solids coatings or paints to provide moisture protection for underground systems.
What is coal tar coating?
Coal tar epoxy is a protective coating consisting of tar, fillers, a gelling agent, and a curing agent. The substance wards off corrosion on equipment used in or near fresh or salt water. It is also resistant to some mild chemicals, acids, and alkali solutions in extreme environments.
How do you mix coal tar epoxy?
Power mix base component before adding activator, then combine at a 4:1 ratio by volume and power mix together. Thoroughly mix for at least two minutes. Note: both components will thicken in viscosity when cold. The material should be warmed to room temperature before mixing for best results.
Why do we use epoxy primer?
It is an airtight sealer that protects the primer before the walls are ready for paint. It also acts as a binding ingredient between the concrete, and the topcoat of the paint. Epoxy primer paint protects the walls from extreme weather conditions.
Can epoxy paint be sprayed?
In general epoxies are a great protective coating that can be sprayed. In order to be able to spray them it is important to consider the pot life, thickness, and target you will be spraying as well as consider the equipment settings you will need to use for best results spraying your epoxy coating.
What is bituminous paint?
What are Bituminous Paints? Bituminous paints, as their name suggests, are bitumen-based coating products designed to be applied in a liquid or semi-liquid form. These paints consist primarily of hydrocarbon materials dissolved in another solvent—such as mineral spirits or naphtha.
