冷鍍鋅漆
The Cold Galvanizing Sealer is a single-component, high-performance coating composed of modified resin and metallic pigments.
It can be used in conjunction with Cold Galvanizing Primer and is applied as a sealer on the surfaces of newly constructed steel structures in harsh industrial corrosive environments.
Effectively seals the zinc particles in the Cold Galvanizing Primer, preventing oxidation and discoloration of the zinc, thereby extending the service life of the coating.
Exhibits excellent resistance to acids, alkalis, salt spray, and more, providing effective protection for metal surfaces against chemical and atmospheric corrosion.
Demonstrates strong adhesion, flexibility, and abrasion resistance, capable of withstanding certain degrees of mechanical impact and wear.
The coating boasts a high-gloss finish with superior decorative effects, imparting an aesthetically pleasing appearance to metal surfaces.

Surface Treatment：
The steel surface to be coated must be thoroughly cleaned of oil, scale, rust, and old coatings. This can be achieved through methods such as shot blasting or sandblasting, reaching the Swedish rust removal standard Sa2.5, with a roughness of 30~70μm. Alternatively, manual rust removal methods can be employed to achieve the Swedish rust removal standard St3, with a roughness of 30~70μm.
Safety Measures：
1、Avoid contact with skin and eyes.
2、If paint comes into contact with skin, wash with warm water or an appropriate cleaning agent. If paint comes into contact with eyes, rinse thoroughly with water and seek medical attention immediately.
3、Ensure adequate ventilation.
4、The paint contains flammable substances. Keep away from sparks and prohibit smoking in the vicinity.
5、Comply with 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).
