Surface preparation/priming

  • Materials to be bonded should be clean and free from dust, grease and other contaminants.
  • Metals shouldbe stored in a warm environment, prior to bonding,toavoid chilling of the glue-line (whichcanlead to extended cure times).

Note: Most pre-finished metals have backing coats which are well-suited to adhesive bonding (sufficient adhesion can be achieved with no primer required in most cases). However, certain grades of Aluminium, Galvanised Steel and Plastics may require the use of a primer; atrialpanel should be prepared in all cases when new materials are to be used in order to determine compatibility levels.


  • The adhesive should be applied evenly over one side of each glue-line usingamechanical roller coater, hand-roller or notched trowel. The amount applied will vary according to the porosity of the substrates,but will normally be in the range of 100-125gsm.
  • After application of the adhesive,a fine mist of atomised water must be applied to the adhesive. The amount required being approximately 10% of the weight of adhesive. The surfaces to be bonded should theninterfaceas quickly as possible to minimise water evaporation, and placed under pressure within the open-time of the adhesive. The pressure required will depend on the nature of the substrates being bonded –but is usually in the range of 0.5 to 0.9bar.
  • Pressure should be maintained,until the adhesive is sufficiently cured to permit handling of the bonded item. Full cure of the adhesive is not obtained for 24 hours and handling within this period should be kept to a minimum.
