TW331 Non-Exposed Oil Based Polyurethane Waterproof Coating is a premium, single-component waterproofing material formulated with high-solid polyurethane. Designed for heavy-duty outdoor and underground conditions, it cures into a tough, flexible, and continuous waterproof membrane that provides long-term protection against water intrusion. The coating bonds strongly to a wide range of construction substrates and is ideal for large-scale industrial and commercial waterproofing projects.
Base | Polyurethane |
Solid Content | 87.8% |
Skin Time | 6h |
Heavy traffic Time | 10h |
Tear Strength | 16N/mm |
Elongation at break % | 612% |
Tensile Strength | 2.17MPa |
Heating Shrinkage Rate | -1.1% |
Adhesive Strength | 1.2MPa |
Aging Test after Heating | PASS |
Water Absorption Rate | 2.0% |
Water-permeable test(120min,0.3MPa) | PASS |
TW331 offers outstanding elongation, high tensile strength, and superior tear resistance, enabling it to handle structural movement, vibration, and substrate cracking without losing integrity.
Upon curing, the coating forms a uniform, joint-free film that effectively prevents water penetration and delivers reliable long-term waterproofing performance.
The formula adheres firmly to various surfaces—including concrete, mortar, metal, and composite materials—often eliminating the need for a separate primer.
Available in standard colors or fully customizable shades based on customer requirements, offering great flexibility for project specifications.
Non-Exposed Oil Based Polyurethane Waterproof Coating is engineered for demanding construction environments where durable, non-exposed waterproofing is required:
Underground structures
Suitable for basements, underground garages, tunnels, shafts, and other below-grade construction.
Outdoor and large-area waterproofing
Ideal for roofing systems, bridge decks, parking structures, and other exposed engineering surfaces that require a robust waterproof membrane.
Store in the original sealed packaging at temperatures of between 0℃ and 30℃, kept in tightly closed packaging. The shelf life is about 18 months when stored in a cool and dry place.
Keep out of reach of children. In case of contact with eyes, please rinse eyes with plenty of water and seek medical advice as soon as possible.
