Fire Retardant Polyurea

Fire Retardant Polyurea

Two component,100% solids,elastomeric pure polyurea membrane developed for applications requiring a fire rated coating. It is designed for situations where the coating should have excellent fire retardant and flame-resistant properties.

Product Details

Fire Retardant Polyurea


PS500B is a kind of material with high crosslinking density and certain elasticity, excellent wear resistance. This polyurea material is a high performance material with 100% solid content, double group, fast curing and field spraying molding. The product is mainly composed of isocyanate semi-prepolymer, terminal amino polyether, polyether polyol, Chain extender, pigment, with high strength, good performance, quick construction of a single molding without seams and other advantages.

Construction method:

1) Spray equipment: Spray polyurea materials must be constructed using a dedicated (1:1) two-component spray equipment. Such as Graco's H-XP3 and so on. 

2) Construction environment requirements: In order to achieve the best coating effect, the site requires ventilation, the ambient temperature should not be lower than 10 °C, the substrate temperature is higher than the dew point of 5 °C, and the air humidity is less than 80%. 

3) Surface treatment of the substrate: 

a. Leveling the cement surface: leveling the substrate with cement mortar. 

b. Grinding of the substrate: the substrate requires fine pitting (to be flat), the surface of the substrate is polished, the scar and the floating slurry are removed, and the position of the negative angle of the yin angle is treated with emphasis, and the yin angle is straight and yang. The corner suggests eight-point angle processing.

c. Cleaning: The dirt on the surface of the substrate cleaned with oil-free, water-free compressed air will clean up the debris that affects the construction of polyurea. 

4) Brush primer: brush the EP1304 or HP6303K concrete special primer, evenly brushed, no leakage coating, no defects. 

5) Scrape putty: Apply putty to seal the trachoma and micropores on the concrete surface. 

6) Spray polyurea: Spray with special polyurea spraying equipment and polyurea spray gun. Use cross method to repair leak spray and reduce stress. 

7) Spraying aliphatic polyurea topcoat: Spraying with special polyurea spraying equipment and polyurea spray gun, spraying evenly without defects and leaking spray. 

Package: Two-component, A component 220KG / 200L barrel, B component 200KG / 200L barrel. 

Color: Spray polyurea material standard color is gray, can also provide other colors according to user requirements.

Safety: Spraying polyurea materials should be equipped with basic labor protection measures during it was be used. It is recommended that operators be equipped with protective clothing, goggles, plastic gloves, masks and other protective equipment. 

Storage/Shelf Life: Ideal storage condition is 0-35 ℃ in cool and dry place, avoid direct sunlight. / One year.
