This advanced adhesive effectively transfers and evenly distributes loads, thereby eliminating stress concentration and preventing corrosion at the assembly interface. Applied in liquid form, ESKONKE retaining adhesive ensures 100% bonding coverage on two metal surfaces. This not only reduces the costs associated with improving part processing accuracy but also significantly enhances assembly process efficiency. ESKONKE Retaining Compound: Key Benefits Filling gaps for seamless fits Locking components to prevent loosening Preventing abrasion and corrosion Improving fit accuracy and reducing design complexity Isolating oxygen to prolong product life Creating leak-proof seals Distributing loads evenly to enhance durability Repairing minor part defects Ideal for industrial applications, ESKONKE simplifies processes, cuts costs, and extends product lifespan. Curing Conditions and Usage Guidelines for ESKONKE Retaining Compound Curing Conditions : Suitable for metal materials; requires air isolation. Ensure the bonding gap is below the maximum specified limit. Components must be at room temperature, dry, and clean. Surface Preparation : Clean surfaces using solvents like trichloroethane, trichloroethylene, methyl ethyl ketone, or methanol. Avoid gasoline, kerosene, or hydrocarbon solvents, as they may leave an oil film. Grinding the metal surface enhances bonding strength. Material Compatibility : Not suitable for pure oxygen or oxygen-rich environments, or for sealing chlorine/oxidizing substances. Avoid use on porous materials (e.g., plastic, wood, paper). Bonds well with active metals (e.g., steel, copper, alloys), offering fast curing and high strength. For inert metals (e.g., stainless steel, zinc, cadmium), curing is slower with lower strength. Verify compatibility before use. Dismantling : Use mechanical tools or heat components to 200–300°C (392–572°F). Alternatively, soak in a specialized scavenger for extended periods. Storage and Handling : Seal immediately after use to prevent evaporation of active ingredients. Do not return unused adhesive to the original container to avoid contamination. Retain the original storage container; do not transfer. To prevent curing during transit, bottles are filled to only half capacity. Store in a cool, dry place (8–21°C/46–70°F), away from direct sunlight. By following these guidelines, ESKONKE retaining adhesive ensures optimal performance, durability, and safety in industrial applications. ## Features - Ideal glue for the installation of smooth/unthreaded cylindrical metal assemblies: 1,Fill the voids and reduce the precision requirements of design, production and installation; 2,Prevent assembly from loosening, wear and corrosion; 3,Evenly distribute loads and stresses during assembly; 4,Sealed from oxygen and other contaminants.

It's not typically used for applications where torque or radial forces are applied. It's used most often for cylinder sleeve installation or other sleeve type applications or when one needs a thread lock that is beyond red level thread lock. I've seen repairs for the outer ring on harmonic balancers being made with epoxy like binary adhesion compounds, i.e. JB Weld **Q: What is required to disassemble the parts? Is heat required?** A: Dear customer, thanks for the question, When dismantling, it can cooperate with mechanical auxiliary equipment and heat the components to 200~300°C (392~572°F), or it can be dismantled after soaking with special scavenger for a long time **Q: Can this be used inside an automatic transmission on pressed in bushings?** A: Will definitely help retain them in place. Get the primer to speed up the cure time. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Review *by J***C on March 10, 2026* ### ⭐⭐⭐⭐⭐ Review *by P***K on April 24, 2026* ### ⭐⭐⭐⭐⭐ Review *by R***G on April 14, 2026* ## Frequently Bought Together - ESKONKE Retaining Compound Green 638 Sleeve Retainer High Strength Cylindrical Metal Components Assemblies Locking and Sealing Anaerobic Glue 1.69 Oz/50 ml - Permatex 85080 Ultra Black Maximum Oil Resistance RTV Silicone Gasket Maker, Sensor Safe And Non-Corrosive, For High Flex And Oil Resistant Applications 9.5 oz - Loctite 1329467 243 Blue Medium Strength Threadlockers, 1.69 Ounces, 50 mL, 3/4" Thread --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.us/products/437377680-green-638](https://www.desertcart.us/products/437377680-green-638) --- *Product available on Desertcart United States of America* *Store origin: US* *Last updated: 2026-05-11*
