Papua New Guinea Indoor Expansive Fire-resistant Coating for Steel Structure (Water-based rough Surface)

Product Characteristics

• China first people-oriented, green and environment-friendly fire-resistant coating product that has passed China Environmental Labeling Product Certification
• It is characterized by early operation time, mature technique, advanced technology and reasonable formula.
• It is also characterized by excellent durability and reliable fatigue resistance. 
• After undergoing 1.2 million times (equal to 30 years) of stress fatigue tests and atmospheric aging resistant tests (equal to 30 years), no pulverization, cracks, scaling-off or peeling-off phenomena occurred to the coating, and the coat adhered to steel members well. This test achievement is pioneering in China. 
• It is applicable to fire protection of supporting steel structures in construction engineering, such as steel structural members, spherical net rack, etc. 

Product information

Basic Compositions ：
Ammonium polyphosphate, melamine, pentaerythritol, chlorcosane, Refractory fiber 

Binder ：
Acrylic emulsion and polyvinyl acetate emulsion do not contain volatile hazardous substances such as asbestos, formaldehyde, benzene, etc.

Base treatment and construction method 

1. Construction should be performed in the form of spraying. Dead-weight spraying gun should be used. The pressure of the air pump for spraying should be 0.4-0.6 Mpa. 
2.Pay attention to the consistency of the paint. It is appropriate when there is no flow of coating during spraying. 
3. Spraying should be performed for 2-3 times according to the refractory grade. The second time of spraying should be performed after the coat is basically cured. 
4. Top coating should be performed after the base layer is total dry. 

Performance indicators 

• Fireproof performance: conform to GB14907-2018 Fire-resistant Coating for Steel Structure 

Storage and Transportation 

• This coating should be stored under 5℃. The shelf life is six months. 
• Anti-freeze and anti-collision measures should be taken for packaging and transportation.
