Main purpose: asphalt polyurethane paint applied to severe corrosive environments underground, underwater and other long-term protection of steel structures. The main advantages: 1, the film tough, abrasion, acid, alkali, salt and other chemical corrosion. 2, good solvent resistance and adhesion, excellent wet heat resistance and impermeability. 3, the construction temperature can be as low as 0 ℃, low temperature curing, winter can replace epoxy asphalt paint. Technical parameters: Color: brown or black composition mode: Two-component solid content: 50% Dry film thickness: 75 microns Theoretical spreading rate: 5.88 m2 / kg mixing ratio; A: B = 17: 3 (WT) Thinner : C004 paint equipment cleaning agents: C004 Drying time: surface dry Hard dry 0.5h 16h (substrate temperature 35 ℃) Surface dry 1 h Hard dry 24 h (Substrate temperature 25 ℃) recoat: minimum time maximum time 8h Without limiting (the substrate temperature 35 ℃) minimum time does not limit the maximum time 24h (substrate temperature of 25 ℃) Flash Point: greater than 30 ℃ (main agent, curing agent mixture) specific gravity: 1.25 Kg / L [1] the technical requirements : 1, the steel surface needs to be blasted up Sa2.5 level, clean and dry. 2, can be used alone, but also supporting the epoxy rust. Construction recommendations: 1, 2 airless spray is recommended for brush or roller 3, does not recommend the use of conventional spray Storage and Management: Store in a cool dry place, storage period of one year security measures: 1, this paint is flammable and containing volatile flammable solvents, it must be away from sparks and open flames. 2, smoking is prohibited in the workplace, and should take effective measures to prevent Mars (such as using explosion-proof electrical equipment, to prevent accumulation of static electricity, avoid metal impact, etc.). 3, construction sites should be kept well ventilated. In order to eliminate any danger of explosion during use, should ensure adequate ventilation in order to maintain the gas / air ratio does not exceed 10% of the lower explosive limit, usually need 200 cubic meters per kilogram solvent ventilation, (associated with the solvent) is able to maintain lower explosive limit of 10% of the working environment. 4, to take effective measures to prevent direct contact with skin and eyes coatings (such as the use overalls, gloves, goggles, face masks, barrier creams). If your skin is accidentally brought into contact with the product, wash thoroughly with water and soap or a suitable industrial cleaners; If the eye is contaminated, please immediately flush with water for at least 10 minutes, and seek immediate medical attention. 5, at the time of construction, it is recommended to wear a mask to prevent inhalation of mist and harmful gases, especially in poorly ventilated environment, but also to pay attention to. Finally, please be handled carefully so as not to pollute the environment of waste paint bucket.
