["r brand new and high qualityr 638 Retaining Compound - high strength. General purpose. Fast curing.r r 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.r r Technical Specifications:r Model: 638r Part No.: 31001r Material: Polyethylene dimethacrylater Color: Greenr Capacity: 50MLr Viscosity: 500 Mpa.sr Density: 1.25r Service temperature range: -50 to +100Cr Product Type: Retaining Compound.r Generic Dimensions: -Locks cylindrical assemblies up to .010' (0.38mm)diameter clearance.r r Features:r High temperature resistancer Tolerates minor contaminants, including industrial oilsr High strength on all metals, including passive substrates (e.g. stainless steel)r Great for shafts, gears, pulleys and similar cylindrical partsr Quantity: 1 pcr Note:r Transition: 1cm=10mm=0.39inchr No retail package.r Please allow 1-2cm error due to manual measurement. pls make sure you do not mind before you bid.r Due to the difference between different monitors, the picture may not reflect the actual color of the item.
