Abrade - to provide a key, abrasion can enhance bond strength by up to 30%.
Clean - using a non-residual surface cleaner.
Prime - using a surface primer chemically alters the surface energy of the substrate to more readily accept adhesive and increases bond strength.
Application - apply bonding tape with the use of a roller, applying firm pressure. Remove liner, apply second substrate and again apply firm pressure to the bond with the roller.
Bond strength is dependant upon the degree of adhesive to surface contact therefore firm application pressure develops better contact and resulting bond strength is improved.
After application bond strength will increase with 60% strength achieved within 20 minutes, 90% after 24 hours and 100% bond strength achieved after 72 hours. Ultimate bond strength can be achieved sooner by exposing bond to high temperatures (i.e. +70oC for 1 hour).
Application Temperature: Ideal application range is +19oC to +25oC
Minimum Temperature: +10oC - Try to avoid applying to surfaces below this temperature as adhesive becomes firmer and condensation will form on substrates. High strength bonding tapes - plastic and crystal can be applied at lower temperatures but condensation must be removed immediately prior to bonding.
Surfaces requiring sealing - most porous surfaces i.e. concrete, wood etc., will require sealing to provide surface integrity. Some materials i.e. copper, brass, galvanised steel and plasticised vinyl may require priming to prevent interaction between adhesive and substrate. Prime glass for applications in areas of high humidity with surface primer.
