Info

Bonding Bonding technology is a very efficient joining method which permits plastics to be permanently joined to themselves or other materials. The chemical joining (bonding) of components offers a range of benefits compared to other joining methods: ˌˌEven distribution of stress ˌˌNo damage to materials ˌˌNo warping of joined parts ˌˌDifferent material combinations can be joined ˌˌThe separating joint is sealed at the same time ˌˌA smaller number of components is required Decisive factors for a good bonded joint: ˌˌMaterial characteristics ˌˌAdhesive ˌˌAdhesive layer ˌˌSurface (preliminary treatment) ˌˌGeometric design of the bonded joint ˌˌApplication and load conditions To increase the strength of a bonded joint, it is advisable to pre-treat the surfaces when bonding plastics in order to enhance surface activity. ˌˌCleaning and degreasing the material surface ˌˌIncreasing the size of the mechanical surface by grinding or sand blasting (particularly recommended) ˌˌPhysical activation of the surface by flame, plasma or corona treatment ˌˌChemical etching for the formation of a defined boundary layer ˌˌPrimer application When bonding plastics, tension peaks should be avoided and a compressive, tensile or shear load should preferably be applied to the adhesive bond joint. Avoid flexural, peeling or plain tensile stresses. Where applicable, the design should be adjusted so that the bonded joint can be configured for suitable levels of stress. When bonding plastics, tensional load should be avoided and a compressive, tensile or shear load should preferably be applied to the adhesive bond joint. Avoid flexural, peeling or plain tensile stresses. Source: DELO Industrieklebstoffe 82
