Chlorinated Rubber Primer

Chlorinated Rubber Primer

A versatile chlorinated rubber anti-corrosion primer composed of chlorinated rubber and anti-corrosive pigments.

Used for steel structure surfaces in both submerged and non-submerged areas.


Product Features


Excellent Chemical Resistance: Withstands corrosion from various chemical media, including acids, alkalis, salts, and oils.

Superior Water and Weather Resistance: Suitable for long-term outdoor use, resistant to sunlight, rain, and freeze-thaw cycles.

Strong Adhesion and Sealing Properties: Adheres firmly to various metal surfaces and effectively blocks contact between corrosive media and the substrate.

Surface Preparation:

    The steel surface to be coated must be thoroughly cleaned of oil, scale, rust, and old coatings. This can be achieved through shot blasting or sandblasting to meet the Swedish standard Sa2.5, with a roughness of 30~70 µm. Alternatively, manual cleaning methods can be used to achieve the Swedish standard St3, with a roughness of 30~70 µm.

 

Safety Measures:

    

1.Avoid contact with skin and eyes.

2.If paint comes into contact with skin, wash with warm water or an appropriate cleaner. If paint gets into the eyes, rinse immediately with plenty of water and seek medical attention.

3.Ensure proper ventilation.

4.The paint contains flammable substances. Keep away from sparks and prohibit smoking in the vicinity.

5.Follow all health and safety regulations on-site.

 

Storage:

    

Store in a dry and cool environment, away from heat sources and open flames. Keep the container tightly sealed.

Shelf life: 12 months from the date of production (at 25°C).
