Permabond Anaerobic Retaining Compound HH040 PURE - Colorless Potable Water Safe

Product Name

- Permabond Anaerobic Retaining Compound HH040 PURE - Colorless Potable Water Safe

Brief Description

- Permabond HH040 PURE is a single-component, colorless, anaerobic retaining compound and sealant. It is specifically formulated to cure in the absence of oxygen when in contact with metal surfaces, creating a strong, durable bond.- A key feature of this product is its NSF/ANSI Standard 61 certification, making it safe for use in drinking water system components.

Popular Applications & Uses

- Precision assembly of press-fitted and slip-fitted cylindrical components.- Retaining bearings, shafts, cylinder liners, and other mechanical parts.- Filling gaps between components to minimize movement, wear, erosion, and pitting.- Preventing corrosion of mated parts.- Bonding pipelines and components in drinking water systems.

Industries that Commonly Use It

- **Pool/Spa/Plumbing:** For sealing and retaining components in potable water systems and infrastructure.- **Construction/Building Services:** In the assembly and maintenance of water treatment facilities and plumbing systems.- **General Manufacturing:** For the assembly of various mechanical parts requiring high-strength retention and environmental resistance.- **Automotive Service/Repair & Transportation/Specialty Vehicle:** For bonding components in engines, transmissions, and other heavy machinery where high-load transmission and vibration resistance are critical.- **Metal Fabrication:** For bonding metal-to-metal assemblies.- **Engineering Services:** Utilized in the design and specification of robust mechanical assemblies.- **Energy:** For components within water treatment and other industrial processes.- **Government & Military:** For infrastructure projects and equipment where NSF-certified materials are required.

Special and Unique Features

- **NSF/ANSI Standard 61 Certified:** Approved for use in drinking water system components, ensuring health effects safety.- **Colorless Formulation:** Ideal for applications where aesthetics or discreet bonding is required. - **High Viscosity:** Allows for maximum gap-filling ability, accommodating less precise machining tolerances.- **Thixotropic Viscosity:** Enables easy and controlled dispensing.- **Single-Component System:** Simplifies application as no mixing is required.

Key Properties

- **Chemical Composition:** Methylacrylates (Anaerobic).- **Cure Mechanism:** Cures in the absence of oxygen when in contact with active metal surfaces.- **Strength:** Provides excellent shear strength and high load transmission.- **Temperature Resistance:** Offers superior environmental and temperature resistance, with a service temperature range typically from -55°C to +150°C.- **Corrosion Prevention:** Prevents fretting corrosion and oxidation of mated parts.

Surface Compatibility

- Primarily designed for bonding metal surfaces.- Best results are achieved on clean, dry, grease-free, and slightly roughened metal surfaces.- Can be used on inactive metals (e.g., zinc, aluminum, stainless steel) with the use of Permabond activators (e.g., A905 or ASC10) to accelerate cure speed.- Not recommended for use in contact with oxygen, oxygen-rich systems, or strong oxidizing materials.- Users should check compatibility with thermoplastics before use.

Known backups / known substitutes

- **Loctite Retaining Compounds:** Such as Loctite 641, Loctite 638, and Loctite 6300 (WRAS-approved for drinking water applications).- **Other Permabond Anaerobic Retaining Compounds:** Including Permabond HH040 (non-PURE version), HM161, MH196, LH050 PURE, MM115 PURE.- **Adhesive Systems (ASI) Anaerobic Adhesives:** Such as ASI 03RC, ASI 09RC, ASI 41RC.

Comparison Note

- While many anaerobic retaining compounds offer high strength and vibration resistance, Permabond HH040 PURE stands out due to its NSF/ANSI Standard 61 certification, making it uniquely suitable for applications involving potable water systems where health and safety standards are paramount. Its colorless and high-viscosity formulation also provides specific advantages for aesthetic and gap-filling requirements.
