1.  Product characteristics.
Chloro-sulfonated polyethylene primer is composed of chloro-sulfonated polyethylene rubber, modified resin, pigment, solvent and so on. It has good adhesion to steel substrate and concrete cement layer. Excellent water resistance and resistance to acid, alkali, salt and other chemical media. Can withstand alternating hot and cold shock (-50℃~120℃), convenient construction, drying very fast. It can cure normally at low temperatures and high humidity.

2. Usage instructions.
(1) Uses.
Chloro-sulfonated polyethylene primer is used for steel structure and equipment surface in the presence of acid, alkali, salt and other strong corrosive media environment, and can also be used for various buildings in the chemical atmosphere corrosion environment as anti-corrosion coating.
（2）Construction requirements.
Thickness of paint film  Primer: Wet film 70μm  Dry film 25μm
Surface treatment: The coated steel surface must be thoroughly cleared of oil, oxidation, rust, old coating, etc. It can be shot or sandblasted to achieve rust removal standard sa2.5 grade ; or manual rust removal method can be used to achieve rust removal standard ST3 grade .
Supporting coatings: chloro-sulfonated polyethylene intermediate paint, chloro-sulfonated polyethylene top paint, chloro-sulfonated polyethylene varnish, etc.

Construction conditions: The ambient temperature must be more than 3℃ higher than the dew point temperature. The relative humidity is not more than 85%.

2.  Caution.
Store at 25 ° C for at least 12 months.
