Product Introduction
This product is composed of two components, AB, which are mixed and cross-linked with moisture in the air to form a polyurea protective film. After solidification, it has the characteristics of high strength, high toughness, high adhesion, aging resistance, corrosion resistance, and wear resistance, making it a new type of protective material.
Main performance characteristics
Long service life, low comprehensive cost, and high cost-effectiveness.
High strength, excellent waterproofing and wear resistance.
Weather resistant, oil resistant, acid alkali salt resistant, and can be directly exposed for use outdoors.
The material has good adhesion to cement base, stone, steel plate, color steel plate, polyurethane foam, etc.
Applications
Concrete anti-seepage, decoration, anti-corrosion, and carbonization prevention in hydraulic engineering, bridges, and other areas, as well as external protection of highway anti-collision piers

Construction technology
Base cleaning → Base repair → Interface agent → Spraying JX9083 polyurea → Inspection → Acceptance
Construction methods
Base cleaning: Polish the base surface until there are no hollows, dust, oil stains, or gaps.
Base layer repair: Scrape and apply the base layer repair agent, which can be applied in stages. Visually inspect the base layer for no holes.
Brush interface agent: Mix the interface agent with a weight ratio of A: B=2:1 evenly and apply it to the surface. The interface agent should be thin and uniform, and should not be missed. The interface agent should be coated with JX9083 two component polyurea after the surface is dry and not sticky. If the interface agent is applied for more than 24 hours, the special activator should be wiped first before applying polyurea.
The usage period of interface agent AB components after mixing is within 1 hour, and it should be based on the principle of less and more frequent mixing to avoid waste.
Polyurea construction: The weight ratio is A: B=2:1. Pour the B component into the A component barrel and stir evenly before construction. When roller coating or using an airless spraying machine for coating, spray in batches until the design thickness is achieved. The recoating time should not exceed 2 hours, as prolonged application may result in recoating failure. The recommended dosage is not less than 0.5kg/m2. After mixing the AB components, they should be sealed and stored until they are used up. They can continue to be used within 24 hours.
Note
Gloves should be worn during construction to avoid contact with eyes and skin. In contact with the skin, scrub with a diluent and then rinse with plenty of water. After coming into contact with eyes and washing them with water, they should be immediately sent to the hospital for treatment.
During construction, it is strictly prohibited for materials to come into contact with water. Before the curing of the coating, it is not allowed to rain, walk or perform other operations.
If dilution is required, please use special diluent, otherwise gel or non curing may be caused.
It is not recommended to construct under conditions where the surface and ambient temperature of the base layer are below 10 ℃ or above 40 ℃.
Ventilation is required at the construction site; Prohibit open flames and fireworks; Do not dispose of materials in the sewer, and keep them out of reach of children.
Packaging And Storage
Packaging: Component A 10kg/barrel, Component B 5kg/barrel
Storage: Can be stored for 12 months in an environment of 15 ℃~25 ℃, with component A stored with the lid down
