描述
Outdoor non-expandive steel structure fire retardant coating -3.0
Product introduction:
Outdoor non-expandive steel structure fire retardant coating-3.0 is a steel structure fire retardant protective coating composed of modified inorganic high temperature adhesive agent, fire retardant, heat insulation, heat absorption and reinforcing materials and chemical additives. Protected by heat insulation, the strength of its steel structure will not cause the building to collapse due to a sharp drop in fire temperature. It has been tested by the National Fireproof Building Materials Quality Supervision and Inspection Center and all performance indicators meet the requirements of national standards. It is a fire-resistant Ideal product for fire protection with good performance and physical and mechanical properties.

Application areas:
This coating is suitable for load-bearing steel structures in various types of buildings such as high-rise buildings, petrochemical industry, electric power, metallurgy, machinery, light textile industry, transportation and warehouses.
Main features:
The coating is non-toxic, does not contain asbestos, has high strength, is moisture-resistant, and is frost-resistant. The coating provides reliable fire protection for building structures.
Construction method:
1. Before construction, the surface of the steel structure must be derusted and coated with anti-rust paint.
2. Ingredients: The ratio of paint is: powder: liquid = 3:2. Mix it evenly and use it up within 1 hour.
3. Construction of base coating: Dust and oil on the surface should be removed before construction. The first coat should be sprayed to a thickness of 3-5mm.
4. In the future, spray 5-8mm thick each time, spray once every 12 hours, and apply to the required thickness.
5. During the construction process and before the coating is dried, the ambient temperature should be above 5°C. Construction should not be carried out on rainy days or when there is frost on the surface of the object or the air humidity exceeds 90%.
Packaging and storage:
Pack and store in accordance with national regulations. The storage environment should be dry, cool, well ventilated, avoid high temperatures, and keep away from fire sources. Packaging containers must be kept tightly closed. The effective storage period is 6 months.
Packing specifications: 25kg/group
Precautions:
1. The slurry should be used together, and the mixing time should be controlled within 30 minutes.
2. The newly sprayed (smeared) coating should be protected from rain before it dries.
3. The paint cannot be stored outdoors or exposed to the sun. Once the bagged powder is opened, it must be used immediately. It must not be used if it is damp or agglomerated. During construction, the prepared paint must be used once to prevent it from drying and solidifying.
4. When the coating surface is required to be flat and smooth, the last spraying process is used for smoothing. When there are requirements for the coating, topcoat can be applied to the surface.

Health and Safety:
Please pay attention to the warning labels on the packaging containers. Use in a well-ventilated environment. Do not inhale paint mist and avoid skin contact. If paint is spilled on skin, wash away immediately with suitable detergent, soap and water. If it splashes into your eyes, rinse them thoroughly with water and seek medical treatment immediately.
