Detailed introduction
| Scope of application: | Waterborne polyurethane floor paint is suitable for badminton courts, basketball courts, outdoor colored road surfaces, asphalt road surface color modification, metal rust prevention, etc | ||
| Coating characteristics: | Good environmental performance, low VOC, and low odor | ||
| Strong breathability, especially suitable for construction on damp floors | |||
| Has good UV resistance | |||
| Excellent physical properties, wear resistance, and chemical corrosion resistance | |||
| TECHNICAL INDEX | Drying time - surface drying: ≤ 1H | ||
| Drying time - practical: ≤ 14H | |||
| Pencil hardness: ≥ 1H | |||
| Impact resistance (500g steel ball): through cm | |||
| Impact resistance (500g steel ball): through cm | |||
| Adhesive strength: ≥ Level 2 | |||
| Resistant to 3% saline solution: no significant change for 7 days | |||
| Water resistance: No significant change after 7 days | |||
| Resistant to 20% sodium oxide gas: no significant change after 7 days | |||
| Resistant to gasoline 120 #: No significant change after 7 days | |||
| Construction procedures | construction method | Main materials - auxiliary materials | Reference amount |
| Plain ground | Do a good job in waterproofing treatment | ||
| undercoat | Roll coated acrylic base oil | DS-F04 | About 0.15kg/m ² |
| screed | Add quartz sand to scrape and apply acrylic intermediate coating | DS-F05- Quartz sand | 0.25-0.6kg/m² |
| Putty layer | Scrape and apply acrylic putty | DS-F05 | 0.5kg/m2 once |
| top coat | Rolling or spraying water-based acrylic topcoat layer | DS-F03 | 0.15kg-0.18/m2 |
| 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) | |||
