With fully owned production facilities and decades of formulation expertise, we source only premium-grade raw materials and implement ISO-aligned quality management systems. This vertical integration allows us to consistently manufacture high-performance EPDM waterproof membrane adhesives that meet both national and international industry standards, backed by reliable supply chains and dedicated technical support.
This EPDM waterproof membrane adhesive is a premium rubber-based bonding agent specifically formulated to address the unique challenges of bonding low-surface-energy EPDM rubber materials. It is designed for lap jointing, seam sealing and full-surface bonding in EPDM membrane installations, providing durable adhesion between EPDM membranes, EPDM and concrete substrates, EPDM and metal surfaces, and EPDM and masonry structures.
It features exceptional initial tack, accelerated curing profile, high ultimate bond strength, excellent water resistance, superior acid and alkali resistance, outstanding weatherability and flexible cured properties. Ideal for roofs, basements, tunnels, water tanks and chemical containment facilities, it creates permanent, watertight bonds that resist glue failure, delamination and seal degradation over time. It is the preferred adhesive for professional EPDM waterproofing installations.
We maintain complete control over the entire manufacturing process—from raw material inspection and formulation optimization to batch production and final quality testing. By operating as a direct factory with no middleman markup, we offer competitive pricing while supporting both small-batch sample evaluations and large-volume continuous supply, ensuring consistent product quality and on-time delivery.
| Performance Index | Requirement |
| Appearance | Uniform liquid, free of stratification and visible mechanical impurities |
| Peel Strength (EPDM Membrane to Substrate/Membrane) | ≥1.2~1.5 N/mm |
| Water Resistance (168 Hours Immersion) | Bond strength retention rate ≥80%, no bond failure or delamination |
| Heat Aging Resistance (168 Hours Hot Air Aging) | Bond strength retention rate ≥70% |
We enforce rigorous enterprise quality standards throughout production. Our products feature uniform consistency, optimal solid content and verified shear strength, delivering batch-to-batch stability and dependable bonding performance that exceeds the requirements of most commercial and industrial waterproofing projects.
Developed exclusively for EPDM rubber waterproof membranes, this adhesive demonstrates exceptional chemical affinity for EPDM materials, causing no corrosion, swelling or discoloration. It creates airtight, watertight lap joints that maintain their structural integrity even under extreme environmental conditions.
With high initial grab and minimal open time, it allows for immediate membrane positioning and alignment, significantly reducing construction downtime. This makes it particularly efficient for large-scale roofing and industrial waterproofing applications.
It offers outstanding resistance to water immersion, acid and alkali exposure, UV radiation and environmental weathering. It performs reliably in harsh industrial environments, outdoor exposure, sub-zero conditions and continuous water contact, matching the 50+ year service life of premium EPDM membranes.
The fully cured adhesive forms a highly flexible, elastic bond line that absorbs stress from building substrate thermal expansion/contraction, structural settlement and vibration. This inherent flexibility prevents cracking, peeling and bond failure under dynamic loading conditions.
Changshu Jiangnan Adhesive Co., Ltd. implements comprehensive quality management across all operations. Every production batch undergoes rigorous testing for appearance, solid content, shear strength and storage stability to ensure 100% compliance with specifications before shipment.
A1: Our EPDM waterproof membrane adhesive is a uniform, viscous liquid with balanced fluidity, making it easy to apply via brush, roller or spray methods on various substrate surfaces.
A2: Non-volatile content ≥25%, shear strength ≥2.0MPa (EPDM-to-EPDM bonding), providing durable, long-lasting adhesion under all service conditions.
A3: It is exclusively formulated for lap jointing, full-surface bonding and edge sealing of EPDM (Ethylene Propylene Diene Monomer) rubber waterproof membranes in all types of waterproofing construction, including chemical containment facilities and wastewater treatment plants.
