Application of Adhesive Tape

 

it is important to appreciate there are 3 factors that can affect the performance of the Bond,and they are,

 

a) The pressure applied to the Surface - all Tapes with an adhesive are classified as '' Pressure Sensitive '' and so any pressure you can apply to the Tape once it has been adhered,will speed up the bond. The Pressure applied may just be in the form of rubbing you hand along the Tape after it has been adhered

 

b) the ambient Temperature and Environmental conditions when the Tape is applied - most Pressure sensitive Tapes need a Temperature in excess of 15 Deg C to begin to bond - Temperatures below this means the adhesive will become more firm and so,will be difficult to bond - warming the Tape in some way will '' soften '' the adhesive and this will assist greatly in establishing the Bond . In relation to the Environmental conditions,typically moisture as a result of high Humidity can also be a potential problem. In instances where moisture appears on the surface of the substrate to which to are going to adhere the Tape,it is vitally important to wipe the surface with a lint free clean cloth in one direction so it is completely dry before applying the Tape

 

c) Clean Surfaces - it is vital that the surface to which the Tape is being applied is dry and free from contaminates. These surface contaminates ( ie Grease,Mould,Rust,Dirt,Dust etc ) will '' deaden ''  the adhesive and greatly affect the bond strength. Often,wiping over the surface in one direction  ( so as to not cross contaminate ) with a lint free clean cloth will suffice . Where the contaminate requires more Robust cleaning,Acetone on a lint free clean cloth would be appropriate - where '' scale or rust  '' needs to be removed from a particularly dirty surface,abrade the surface with a sanding disc,then wipe clean with Acetone a lint free cloth in one direction ( do not use Methylated Spirits )
