The pure polyurea engineering of pipe was sprayed in June, 2018. It is located in Rizhao city, Shandong province and the total spray area is 1750 square meters. We sprayed our Qtech-404 polyurea product to the pipe. Our pure polyurea coating has achieved very good corrosion resistance, waterproof and appearance effects.
The construction process is as followed:
1. Clean the substrate. Surface must be properly prepared. Remove all oil, dust, grease, dirt etc to ensure adequate adhesion.
2. Fill the crack with polyurea joint filler.
3. Primer application.
4. First we need to block the thing not needing spraying to avoid spraying contamination on its surface. Then we can spray pure polyurea.
The physical properties of Qtech-404:
Tensile Strength/MPa | >20MPa |
Tear Strength(N/M) | >70 |
Elongation/% | >400 |
Shore Hardness | >A85 |
Abraision Resistance/(GB/T 1689-1998, cm3/1.61km) | <0.20 |
Adhesion/(Pull off, MPa) | >10(Steel), >3(Concrete) |
Chemical Resistant/(2000hours): | No blister, No Corrosion, No Spalling |
Gel Time/s | <16 |
Tack free/s | 20~30s |
Spraying polyurea elastomer coating is a kind of high performance coatings without solvent and pollution. It’s performance can be widely adjusted to suit different spray environment and the performance requirements. The pure polyurea is no-solvent but can cure quickly. Furthermore, pure polyurea can be sprayed in any surface.
ANY PLACES CAN USE POLYUREA COATING FOR ANTICORROSION, ANTIABRASION, ANTI IMPACT, ANTI SLIP.
