Bonding plastics now easier for manufacturers
Bonding plastics now easier for manufacturers
Keywords: Symonds Cableform, Adhesives, Plastics, Metals, Composites
Symonds Cableform of Welwyn Garden City has introduced a new structural adhesive for bonding plastics - coded 5420. The company says that the adhesive, a flexible structural methacrylate, can give bond strengths on ABS which will produce substrate failure - not bond failure. Gap filling is up to 3mm.
In addition to ABS, 5420 can bond PVC, polyurethane, acrylics and fibreglass as well as a wide variety of common plastics and composites. Typical applications include bonding parts, large and small, in automotive manufacture and aircraft components.
An additional benefit claimed is that most applications do not require primers or surface preparation.
As well as plastics and composites, 5420 will bond aluminium, steel and galvanised metals.
5420 is said to be a solvent free, two-part adhesive with a 1:1 mix ratio for application direct from cartridges or automated systems and will, claim Symonds, retain its bond strength in boiling water, salt water, salt fog, all common fuels, antifreeze and hydraulic oils and cutting oils.
