How to apply PSA

Step 1: To bond optimum adhesion, the bonding surface must be clean, dry and well unified. Typical surface cleaning solvents are isopropyl alcohol/water mixture(rubbing alcohol) or heptane. Note : Be sure to follow solvent manufacturers’precautions and directions for use when using solvents. 
Step 2: Use roller or scraper to press tape laminated on the dry substrate surface with15 psi pressure, and let it be well bonded.
Step 3:  For hand lamination, use a plastic squeegee, with firm, uniform pressure and keeping the adhesive off the substrate until pressure contact is made to prevent
entrapment of air.
Step 4: Remove the liner and then laminate the applied material on the tape, and apply 15 psi pressure on the material to be well bonding. If making sure removing
airtrap, add more pressure can be done, under not destroying the adherent. The recommended parameters are 15psi pressure for 15 seconds.
Step 5 : After application, the bond strength will increase as the adhesive flows onto the surface. At room temperature approximately 50% of the ultimate strength will be achieved after 20 minutes, 90% after 24 hours and 100% 72 hours. In some cases bond strength can be increased and ultimate bond strength can be achieved more quickly by exposure of the bond to elevated temperature ( e.g.150F (66℃) for 1 hour ). This provides better adhesive wetout onto the substrate. 
Step 6 : Suggest operation temperature is between 15℃ and 38℃, and not under 10℃.
Step 7: For serving high quality tapes, the storage condition is recommended 21℃ and 50% related humidity.
Step 8: In ATT, it is necessary to avoid the shaped tape contacted with each other in their profiles of the adhesives
