JX3310 Non-bituminous Non-curing Rubber Waterproof Coating is a "non-asphalt based" waterproof coating made of rubber, resin and various additives. It contains no asphalt and delivers stable and reliable performance as a new type of eco-friendly waterproof material. It will not cure after long-term exposure to air and is insoluble in water with ultra-high bonding strength, adapting to the complex construction surfaces. It can automatically locate water leakage points and repair damaged waterproof layers. It provides permanent waterproofing and is solvent-free, complying with the national safety and environmental protection purpose. Featuring outstanding creep property, excellent waterproof performance and aging resistance, it can be applied via brushing, spraying, grouting for leak stoppage and other construction methods. It can work together with waterproof membranes to form a composite waterproofing system.

Scope of Application

• Suitable for substrates with large undulations and high stress, as well as areas with predictable or frequent deformation.

• Especially suitable for the projects where open-flame construction is prohibited.

• Applicable to waterproofing works for roofs, underground structures and other projects.

Product Classification

Classified into Type Ⅰ and Type Ⅱ based on basic performance. Type Ⅱ is more suitable for vertical walls.

Reference Dosage

1.2kg~1.5kg/㎡ per mm thickness

Performance Standard

《Non-asphalt Non-curing Rubber Waterproof Coating》Q/JX0300-2023

Product Features

• Unique red non-asphalt polymer resin, more eco-friendly than asphalt-based products. No obvious smoke during application with stronger adhesion.

• Excellent creep property and elongation, great substrate adaptability. When the substrate cracks and stretches the waterproof layer, the non-curing rubber layer absorbs stress to maintain long-term integrity of the whole waterproof system.

• Great chemical corrosion resistance, aging resistance and remarkable self-healing capacity. If the waterproof layer is punctured by external force, the damaged area will not expand. The creep property of the material can self-repair minor leakage.

• Superior composite waterproof performance: Forms "skin-type" bonding when combined with waterproof membranes for better integrity and an upgraded waterproofing grade.

• Outstanding high & low temperature resistance and ultra-strong bonding force. Suitable for both hot and cold climate zones. Bonds well to various substrates and maintains good adhesion even on damp bases.

• Good workability. Solid content over 99%. It can be pumped for continuous construction and applied to designed thickness in one pass for fast construction speed.

Construction Process

JX3310 Non-asphalt Non-curing Rubber Waterproof Coating can be applied by spraying or troweling.

• Select construction method according to site conditions. Before construction, inspect the integrity of spraying equipment, clean the spray gun, raw material pipelines, filter screens and valves, and test the sprayer for normal operation.

• Detail treatment: Pre-treat details such as internal/external corners and transitions between horizontal and vertical surfaces by troweling to a thickness of 2mm, then cut membranes to matching the shapes and apply. Carry out full-area construction after the additional layer is finished to guarantee uniform coating thickness.

• Large-area spraying: After substrate cleaning, open the heating tank and fill with pre-melted material. Heat until the coating reaches sprayable temperature (160℃). Apply evenly with dedicated spraying equipment. Different spray nozzles can be selected according to designed thickness. The waterproof layer can be formed in one pass to meet design requirements.

• After spraying a certain area, test the coating thickness with needle gauge before membrane installation. If thickness is insufficient or local reinforcement is needed, supplement by manual troweling. Spraying shall be completed by sections.

• Lay waterproof membrane promptly after spraying to prevent excessive dust from adhering to coating surface and weakening bonding. Apply the coating within membrane overlap area, then roll the overlapped seams with roller. Foot traffic is allowed right after membrane laying, marking the completion of construction.

Notes

• Construction ambient temperature: 0~35℃. Construction is forbidden in rain, snow or when wind force reaches Grade 5 or above.

• Heat and stir the coating thoroughly before use. Recommended troweling temperature: 130 to 140℃; spraying temperature: 160 to 170℃. The heating temperature must not exceed 180℃; otherwise, material performance will be impaired.

• The construction involves heating, spraying, mechanical and electrical operations. On-site supervision by professional technicians is required.

• Take precautions against electric hazard, fire and scald at site. Workers shall wear PPE and prepare corresponding first-aid supplies.

• For vertical wall application, fix or build protective walls after waterproofing to prevent membrane sliding.

• The non-curing coating is fully compatible with TPO, EPDM, butyl polymer membranes (except EPDM) and asphalt membranes for direct membrane lap joint.

Transportation & Storage

• Sealed iron drum packaging, store in dry place and stack by category.

• Keep away from fire sources, avoid direct sunbeam and rain, prevent collision and ensure ventilation.

• Storage temperature ≤40℃.
