What is Epoxy Primer?
Areas of use and suitable primers and topcoats
Recommended Uses It can be used as the first coat in epoxy coating systems on concrete surfaces or as a pigment-free epoxy clear coat in multi-layer clear coat systems. Suitable Primers Epoxy Sealer
Application Details
Surface preparation All oil, grease, dirt and other contaminants must be removed from the surface. Mixing Instructions After thoroughly mixing component A with a suitable mixer, gradually add component B and mix thoroughly for 5 minutes. Let the mixture sit for an additional 5 minutes before diluting to allow for pre-reaction time. Do not dilute each component separately. Theoretical Consumption 120 gr/m² – 30 Micron KFFT Pot life 2 hours at 25°C
Properties of epoxy primer
Epoxy primer is the most basic layer applied to the surface. There are different types of this primer, including the following.
- Solvent-based epoxy primer: This primer is diluted using solvent and dries quickly.
- Solvent-free epoxy primer: This type of primer is made without using solvents and has less odor.
- Colored epoxy primer: This type of primer is available in different colors and can be used for different surfaces.
You should choose the appropriate epoxy primer according to the type of surface to be primed. It is also necessary to pay attention to environmental conditions such as humidity, temperature and UV radiation. The selected primer should also be compatible with polyamine epoxy paint.
Epoxy primer applications
Epoxy primer has wide application in various industries due to its high adhesion to various surfaces, excellent chemical resistance and anti-corrosion properties. Some of the most important uses of this primer are as follows.
Substructure for epoxy coatings:
This primer helps improve the adhesion of epoxy coatings to a variety of surfaces, including concrete, steel, wood and stone, as a first coat. This increases the durability and overall strength of the epoxy coating.
Epoxy floors:
This primer is used as a base layer for epoxy floors and can create a smooth and solid surface. Epoxy floors containing this primer are used in various places such as factories, warehouses, garages, as well as commercial and residential areas.
Other applications:
Besides the mentioned situations, this primer is also used in coating of pipes and tanks, coating of pipelines, electrical insulation in the aerospace and composite industries.
Protection of metal surfaces against corrosion:
Due to its excellent anti-corrosion properties, this primer can protect metal surfaces against rust and other types of corrosion.
Moisture insulation:
Epoxy primer can be used as a moisture barrier on various surfaces such as concrete, stone and metal due to its high resistance to water and moisture. This primer prevents water and moisture from penetrating the surfaces and causing damage.
Advantages of using epoxy primer
The use of two-component epoxy primer is associated with many advantages, among which are the following.
- Increases adhesion: Increases the adhesion between the paint and the surface.
- Pore filling: It creates a smooth and even surface for the paint by filling the pores on the surface.
- Metal protection: Protects metal against corrosion and rust.
- Moisture resistance: Increases the resistance of the surface to moisture.
Safety tips
Epoxy primer can cause skin and eye irritation; therefore, direct contact with skin or eyes should be avoided. This material can release harmful fumes. Therefore, it is better to use it in a well-ventilated area. Finally, it is mandatory to use gloves, goggles and protective clothing when working with this primer.
Storage conditions
Epoxy primer should be stored in a dry and cool environment, away from sunlight. The storage environment should be equipped with a suitable ventilation system.
