["Description: and 638 Retaining Compound - high strength. General purpose. Fast curing. 638 is designed for the bonding of cylindrical fitting parts, particularly where bond gaps can approach 0.38mm. The product cures when confined in the absence of air between close-fitting metal surfaces and prevents loosening and leakage due to shock and vibration. It not only works on active metals but also on passive substrates, exhibiting robust cure performance. The product offers high-temperature performance and good oil tolerance, and tolerates minor surface contaminants. Technical Specifications: Model: 638 Part No.: 31001 Material: Polyethylene dimethacrylate Color: Green Capacity: 50ML Viscosity: 500 Mpa.s Density: 1.25 Service temperature range: -50 to and100°C Product Type: Retaining Compound. Generic Dimensions: -Locks cylindrical assemblies up to .010'' (0.38mm)diameter clearance. Features: High temperature resistance Tolerates minor contaminants, including industrial oils High strength on all metals, including passive substrates (e.g. stainless steel) Great for shafts, gears, pulleys and similar cylindrical parts Quantity: 1 pc Note: Transition: 1cm=10mm=0.39inch No retail package.
