Polyurethane anti-corrosion paint

First, composition
     Modified polyurethane heat-resisting resin polymerized with hydroxyl-containing resin and polyisocyanate as main film-forming substance
Auxiliaries, hardeners, etc., composed of primer and top coat, two-component packaging.
Second, performance:
     With a sudden change in heat and temperature resistance, long-term heat resistance 300 °C, and has excellent heat and corrosion resistance, acid and alkali resistance, resistance
Brine, resistant to various types of chemical atmosphere, etc., curing at room temperature, fast drying, good adhesion of bottom and topcoat.
Third, use:
     Suitable for metallurgy, chemical, electromechanical, mechanical and other industries, metal surface heat and corrosion, in the blast furnace hot blast furnace inner and outer walls, flue, exhaust
Tubes, furnaces, heat exchangers, and other high-temperature surfaces of metals are widely used, with significant results.
 Fourth, performance indicators:
No Items Indicators
1 Appearance of paint film Smooth and smooth paint film
2 Viscosity (Coated - 4 cups) S      ≥ 40
3 Drying time h Dry ≤ 2
Hard work ≤ 24
4 Adhesion level    ≤ 2
5 Impact strength kg·cm 50
6 Heat resistance °C 300
7 Acid resistance(5%H2S04)    h 72h is not blistering, does not fall off
8 Alkali resistance(5%Na0H)    h 72h is not blistering, does not fall off
9 Salt tolerance(3%NaCL)    h 72h is not blistering, does not fall off
Fifth, surface treatment:
    The metal surface must be cleaned mechanically or manually to remove surface impurities such as rust, oxide scale, oil, etc. up to St2 level.
Sandblasting Sa2.5 level, better.
Six, packaging and ratio:
Bottom and topcoat two component packaging, Group A: paint 20kg, Group B: curing agent 5kg, 4 to 1 (weight ratio) mixing and mixing
Use after curing for 20 minutes.
Seven, it is recommended that the number of coating channels: a primer, topcoat two to three, depending on the need for coating thickness.
Eight, storage period: 12 months.
Nine, safety precautions:
(1) The paint should be placed in a ventilated and dry place away from the fire and avoid direct sunlight.
(2) No open flame is allowed on the construction site.
(3) In the construction of enclosed places, ventilation must be emphasized. Painters and constructors should wear protective equipment to avoid poisoning.
 (4) Before the paint film is completely dry or the paint film is solidified, protective measures should be taken to avoid rain showering and trampling.
