| Scope of application: | A four component high-performance polyurethane composite flooring material, which combines almost all the advantages of organic polymers and inorganic concrete, is particularly suitable for use in extreme industrial environments such as food hygiene, chemical corrosion, high temperature and humidity, water wet and slippery, low temperature freezing, and heavy load and strong impact. Water based green, low-carbon and environmentally friendly |
| Coating characteristics: | Strong impact resistance, high wear resistance, and a service life of up to 20-30 years |
| Resistant to high and low temperatures of -40~130 ° C |
| Excellent water vapor permeation function |
| Extremely low VOC emissions |
| Rapid curing performance |
| TECHNICAL INDEX | Drying time - Table drying：≤4H
|
Drying time - practical：≤24H
|
| Shore hardness：≥80d |
| impact resistance（500g steel ball）：通过g.cm |
| wear resistance（750g/500r）：≤0.01g |
| Compressive strength: ≤ Grade 2 |
| 24-hour compressive strength: ≥ 30mpa |
| 7-day compressive strength: ≥ 45mpa |
| Water resistance: No significant change after 7 days |
| Resistant to other chemicals: no significant changes within 7 days |
| Construction procedures | construction method | Main materials - auxiliary materials | Reference amount |
| Plain ground | Plain cutting seam (not less than 80 * 80) |
| The dosage is determined based on the thickness |
| undercoat | Scrape and apply polyurethane base oil | DS-609 |
| top coat | Add an appropriate amount of quartz sand and apply polyurethane mortar for the first layer of self leveling | DS-609 |
| Apply polyurethane mortar self leveling for the second time | DS-609 |
| After completion, the overall floor will be bright and clean, with uniform color and no hollowing |
|
| Construction procedures | Coating thickness: generally 1mm-3mm. If it exceeds 2mm, it needs to be sandblasted |
| Personnel can only enter after 24 hours of construction completion, and heavy pressure can only be applied after 72 hours. (Based on 25 * C, the low-temperature opening time needs to be moderately extended) |
