Polyurethane Waterproofing Coating (1K / 2K / Waterborne)
Seamless, high-elongation polyurethane liquid membrane for below-grade and wet areas. Choose one-component for speed, two-component (incl. graphene KS-911C) for thick films and tanks, or waterborne Aquacoat 590 for low-odour occupied buildings — all from Keshun AQUACOAT.
Keshun AQUACOAT Series — produced by Keshun Waterproof Technologies (SZSE: 300737)
System Selector
| System | Best For | Notes |
|---|---|---|
| 1K moisture-cure | Quick jobs, details and repairs | Brush/roller straight from the tin |
| 2K (e.g. KS-911C graphene, KS-939) | Basements, tanks, thick films | High build in fewer coats; potable-water grades on request |
| Waterborne (Aquacoat 590) | Occupied buildings, low VOC spec | Low odour, easy clean-up |
| Exposed-grade (HW-680) | Exposed roofs & pedestrian decks | UV-stable topcoat system |
QA & Application Notes
Primer on porous substrates; detail reinforcement with polyester fleece at corners and joints; film-build verified by wet-film gauge; water test (ponding) after full cure before handover. Elongation and tensile data per datasheet — copies of SGS reports provided with offers.
