Uv treatment, % ≥ 150 65
5 low temperature flexible, pure Φ 10 mm rod - 10 ℃ - no crack
6 is impermeable, 0. 3Mpa, 30min impervious to water
7. Bond strength of wet substrate, Mpa≥ 0. 5 to 1. 0
8. Impermeability (back water surface), Mpa≥ -- 0. 6
Note: 1) if the product is used in underground engineering, the project may not be tested.
2) if the product is used in underground waterproof works, the project must be tested.
2. Material preservation: liquid materials should be stored in a cool place above 5℃, and powder materials should be stored in a dry place. Shelf life is 6 months.
3, construction conditions: can not be under 0℃ or rain construction. Otherwise, it doesn't film very well.
4, scope of application: the coating can be in a dry or slightly damp masonry, mortar, concrete, metal, wood, hard plastic, glass, gypsum board, foam board, asphalt, rubber and SBS, APP, polyurethane waterproof materials such as base construction, for the old and new buildings (building, underground engineering, tunnels, Bridges, pool, reservoir, etc.) can be used. At the same time, it can also be used as binder and exterior decoration paint.
5, usable time: in the liquid: powder: water = 10:7:2, the ambient temperature is 20℃, the usable time of coating is about 1 hour. The site environment temperature is low, the usable time is longer; Or shorter. When the material is thick and hard, it should not be reused with water.
6, dry curing time: in the liquid: powder: water = 10:7:2, the ambient temperature is 20℃ in the open air, paint dry curing time is about 3 hours. The site environment temperature is low, the humidity is large, the ventilation is poor, the dry solidification time is longer; Or shorter.
7, coating color: the natural color of the coating is white, add 5% to 10% of liquid weight of inorganic pigment, can be made into a variety of color coating.
