    Use of epoxy coating

    Epoxy coatings are mainly used for steel anticorrosive topcoats and concrete surfaces.

    Scope of application: underground parking lot floor, various acid-base ponds, inner walls of desulfurization towers, sewage treatment ponds, etc.


    Advantages of epoxy coatings

    01 Excellent adhesion

    Epoxy coatings have excellent adhesion to the coating of steel structure substrates and concrete surfaces, and the adhesion is very firm during coating, and the paint is not easy to fall off.

    02 Excellent mechanical properties, wear resistance, impact resistance

    Epoxy paint film is tough, impact resistance, wear resistance, toughness and bending resistance.


    It is suitable for the coating of mining machinery and engineering facilities that are frequently rubbed, impacted, and stoned, and it is not easy to cause cracks due to temperature changes and other factors.


    03 Excellent corrosion resistance and impermeability

    The epoxy resin has a stable structure, which makes the coating resistant to acid, alkali, and organic solvents.
    After the epoxy paint is cured, the structure is dense, which makes it difficult for corrosive substances to penetrate and has strong impermeability.

    Disadvantages of epoxy coatings

    Epoxy coatings are not suitable for outdoor anti-corrosion, but they can also exert excellent effects if applied to other fields.
