This optimization results in a high tolerance to oily surfaces, improved thermal resistance (up to 180 ° C), passive surfaces and improved polymerization speed.
These new formulas of anaerobic adhesives developed by Henkel are the guarantee of a product whose performance is not affected on the surfaces poorly cleaned, thus resolving a recurring problem in the manufacturing processes. They provide excellent curing on all metals including passive supports such as stainless steel. This allows for more flexibility in the choice of substrates and parts designs.
These fastening adhesives of course retain their initial properties of polymerization rate, bond strength, polymerization on passive surfaces, chemical resistance and service life.
Particularly suitable for fixing cylindrical assemblies, studs and bearings, the LOCTITE 638 and LOCTITE 648 fastening adhesives allow a very good load capacity and a uniform stress distribution while eliminating galvanic corrosion. Unlike conventional assemblies where machine maintenance operations are expensive, the use of the LOCTITE 638 and LOCTITE 648 ensures a more reliable and less costly assembly.
LOCTITE 638 is a high strength, high viscosity fastener recommended for applications with diameters up to 0.25 mm.
LOCTITE 648 is a high strength, low viscosity fastener suitable for applications with diameters up to 0.15 mm.
