With self-owned production facilities and proven formulation expertise developed over years of industry practice, we source only premium-grade raw materials and implement comprehensive quality control systems. Backed by reliable supply capabilities and dedicated technical support, we provide high-performance Stainless steel adhesives products that fully comply with national and international industry quality standards.
This Stainless steel adhesives is a two-component epoxy adhesive that retains the versatile bonding properties of 504 all-purpose adhesive while being specifically engineered to address the unique challenges of bonding stainless steel to PTFE. It also effectively bonds a wide range of other difficult-to-adhere materials, creating strong, durable bonds between stainless steel and PTFE, as well as various metal substrates. Featuring room-temperature curing, non-toxic formulation, exceptional bond strength, user-friendly application and customizable color options, it forms a tough, resilient bond line that resists cracking and delamination over extended service life. It is the ideal bonding solution for stainless steel and PTFE components in the chemical, electronics, machinery and sealing industries.
We maintain complete control over the entire production lifecycle—from raw material qualification and formula optimization to manufacturing mixing and final quality inspection. By eliminating middleman markups, 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 |
| Component A Appearance | Milky white viscous paste |
| Component B Appearance | Light yellow viscous liquid |
| Curing Time | ≤ 24 hours |
| Tensile Strength (A3 Steel, Steel-to-Steel) | ≥ 25 MPa |
| Shear Strength (A3 Steel, Steel-to-Steel) | ≥ 18 MPa |
Specifically developed for bonding stainless steel to PTFE and other challenging substrates, it creates robust, long-lasting bonds that solve the persistent industry problems of poor adhesion and premature bond failure associated with conventional adhesives. It also retains the versatile bonding capabilities of 504 all-purpose adhesive for multi-scenario applications.
We strictly enforce enterprise quality standards throughout manufacturing. Component A is a uniform milky white paste, while Component B is a clear light yellow liquid. With curing time ≤24 hours, tensile strength ≥25MPa and shear strength ≥18MPa on A3 steel substrates, it delivers consistent, dependable bonding performance batch after batch.
The 2:1 mixing ratio allows for easy preparation, and curing occurs naturally at ambient temperatures without requiring heating or pressurization. The non-toxic formulation ensures safe handling, and it is compatible with both manual brushing and automated dispensing equipment, reducing application costs and complexity.
We can formulate the adhesive in a wide range of colors including red, yellow, green, black and purple to match specific product designs, providing both functional bonding and aesthetic integration for high-end stainless steel products and specialized applications.
The cured adhesive does not stain or damage stainless steel or PTFE surfaces. It maintains stainless steel's inherent corrosion resistance and easy-to-clean properties, while preserving PTFE's critical insulation, non-stick and chemical resistance characteristics, ensuring complete functional integrity of the finished product.
Changshu Jiangnan Adhesive Co., Ltd. implements comprehensive quality management across all operations. Every production batch undergoes rigorous testing for appearance, mixing ratio, curing time, tensile strength and shear strength to ensure 100% compliance before shipment. We support both sample orders and bulk supply with reliable delivery schedules.
