Operating our own modern production facilities with decades of specialized formulation experience, we utilize only top-quality raw materials and maintain strict quality management systems. Supported by reliable production capacity and professional technical assistance, we deliver high-performance PTFE adhesive products that fully comply with national and international industry quality benchmarks.
This PTFE adhesives is an advanced two-component epoxy adhesive system. While maintaining the universal bonding properties of 504 all-purpose adhesive, it is specifically engineered to overcome the inherent difficulties of bonding PTFE to stainless steel and other hard-to-adhere materials. It creates exceptionally strong and durable bonds between PTFE and stainless steel, as well as various other metal substrates.
With ambient temperature curing, non-toxic formulation, superior bond strength, easy application and customizable color options, it forms a tough, flexible bond line that resists cracking and delamination even under long-term service conditions. It is the optimal bonding solution for PTFE components and stainless steel assemblies in chemical processing, electronics manufacturing, machinery production and industrial sealing applications.
We exercise complete control over every aspect of production—from raw material sourcing and formula development to manufacturing mixing and final quality testing. By selling directly from our factory with no intermediary markups, we offer competitive pricing while supporting both small-batch sample testing and large-volume continuous supply, ensuring consistent product quality and on-time delivery.
| Performance Parameter | Standard Requirement |
| Component A Appearance | Milky white viscous paste |
| Component B Appearance | Light yellow viscous liquid |
| Complete Curing Time | Maximum 24 hours |
| Tensile Strength (A3 Steel, Steel-to-Steel) | Minimum 25 MPa |
| Shear Strength (A3 Steel, Steel-to-Steel) | Minimum 18 MPa |
Specifically developed for bonding PTFE to stainless steel and other notoriously difficult substrates, it creates robust, long-lasting bonds that eliminate the common issues of weak adhesion and premature bond failure experienced with conventional adhesives. It also retains the versatile bonding capabilities of 504 all-purpose adhesive for general industrial use.
We strictly enforce enterprise quality standards throughout the manufacturing process. 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 reliable, consistent bonding performance batch after batch.
The simple 2:1 mixing ratio allows for easy preparation, and curing occurs naturally at room temperature without the need for heating, pressurization or specialized equipment. 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 meet specific product design, branding and identification needs, providing both functional bonding and visual integration for high-end products and specialized applications.
The cured adhesive does not stain, corrode or damage PTFE or stainless steel surfaces. It maintains PTFE's essential properties of electrical insulation, non-stick characteristics and chemical resistance, while preserving stainless steel's corrosion resistance and clean appearance, ensuring the complete functional integrity of the finished product.
Changshu Jiangnan Adhesive Co., Ltd. implements comprehensive quality management across all operations. Every production batch undergoes thorough testing for appearance, mixing ratio accuracy, curing time, tensile strength and shear strength to ensure 100% compliance before shipment. We support both sample evaluation and bulk production with reliable delivery schedules.
A1: This is a two-component adhesive system. Component A is a milky white viscous paste, and Component B is a light yellow viscous liquid. They must be mixed thoroughly in a 2:1 weight ratio before use.
A2: Full curing is achieved within 24 hours at standard room temperature. It provides excellent mechanical performance with tensile strength ≥25MPa and shear strength ≥18MPa on A3 steel substrates, creating strong, durable bonds that can withstand demanding operating conditions.
A3: It is specifically engineered for bonding PTFE (Polytetrafluoroethylene) to stainless steel and other difficult-to-adhere materials, while also offering the versatile bonding capabilities of 504 all-purpose adhesive for general industrial applications.
