One-component Polyurethane Waterproof Coating For Tunnel And Utility Tunnel Municipal Project
Product Introduction
One‑component polyurethane waterproof coating is moisture‑curing reactive polymer waterproof material, manufactured from polyether polyol, isocyanate, fillers and functional additives. Ready‑to‑use out of drum. It cures by chemical reaction with moisture from ambient air to form continuous, dense, rubber‑like seamless waterproof film at room temperature. No on‑site proportioning required to avoid mixing errors. Widely applied for non‑exposed civil, industrial and municipal waterproof projects.
Product Features
Key Construction Points
| No. | Item | Precautions |
| 1 | Substrate | Substrate must be solid & dry, free of standing water, dust and oil; interface treatment required for damp surface |
| 2 | Mixing Ratio | Weigh A & B strictly by weight ratio; wrong ratio causes uncured sticky or brittle film |
| 3 | Stirring | Electrically stir 3-5min until uniform; poor mixing causes partial curing failure |
| 4 | Pot-life | Use up within pot-life after mixing; discard gelled material, do not dilute with water |
| 5 | Coating Layers | Apply thin multi-coats in cross directions; avoid heavy coat to prevent blistering & sagging |
| 6 | Temperature/Humidity | Construct at 5℃-35℃; low temp slows curing; avoid rainy and dewy days |
| 7 | Ventilation | Keep ventilated, avoid inhaling volatile gas, wear protective equipment |
| 8 | Details | Apply extra reinforcement layer on corners, pipe roots and floor drains first |
| 9 | No Direct Exposure | Film is not UV-resistant; mortar protective layer mandatory for exposed areas |
| 10 | Tool Cleaning | Clean tools with special cleaner before curing; hard to clean after curing |
| 11 | Curing Protection | Avoid rain, ponding, treading and sharp-object damage during curing |
| 12 | Moisture Content | Standing water reduces adhesion and causes blistering; moisture content must meet requirement |
