Descriptions | The special primer for polyurea uses high-performance polyurethane resin prepolymer and polymer materials as the main film-forming materials. The main function is to penetrate the substrate and close the pores on the base surface to increase the adhesion between the polyurea and the substrate. |
Features and advantages | 1.Significantly improve the adhesion between the base surface and the coating. 2. Low viscosity and excellent fluidity. 3.Excellent sealing and high permeability. 4. Excellent water resistance, heat and humidity resistance, and corrosion resistance. |
Application scopes | Surface anticorrosive coating of concrete, iron-based, marble, wood and other substrates. |
Product information | Component A: light yellow liquid Component B: transparent liquid |
Physical properties | Bonding strength (MPa): dry base surface ≥ 2.5 (concrete) dry base surface ≥ 4.5 (iron base) retention rate after immersion ≥ 95% |
Corrosion performance | It can withstand the erosion of water, sea water, acid, alkali, salt and other media. |
Packing | Component A: 18KG/barrel Component B: 12KG/barrel |
Construction environment | Ambient temperature ≥5ºC, air humidity ≤85% |
Construction Notes | 1. During construction, the temperature of the substrate must be 3°C higher than the dew point temperature. 2. Before the product is used, component B should be fully stirred. 3.It is strictly forbidden to add any thinner. 4. When constructing in a confined space, maintain good ventilation. 5. When using this product, you need to wear work clothes, goggles, gas masks, gloves and other protective equipment. |
The corresponding curing time | At 25ºC, 4H |
Shelf life | 12 months |
Caution information for transportation and storage | 1. The storage temperature should be 5-35ºC. 2. Store in a cool and ventilated environment, avoid direct sunlight, prohibit close to fire sources, and prevent collisions. |
Integrity statement | The primer product series complies with the building materials industry standard JC/T 2252-2014 (primer coating); all the data listed are obtained in the relevant laboratory in accordance with the corresponding standard test. The relevant data during the test will be slightly different due to the different test environment and methods. Significant difference.
