Figure 6. Effect of coat weight on adhesive properties of pressure-sensitive adhesives (PSAs) using different backing membranes. (a) Probe tack test with

stainless steel (SS) probes with pressure-sensitive adhesive (PSA)-4302 coating (5, 10, and 15 mg/cm ) on glass and backing membranes 9733, 9723, and
2
9735. (b) Probe tack test with polypropylene (PP) probes with PSA-4302 coating (5 and 10 mg/cm ) on glass and backing membranes 9733 and 9735. (c)
2
Probe tack test with SS probes with PSA-4501 coating (5, 10, and 15 mg/cm ) on glass and backing membranes 9733, 9723, and 9735. (d) Probe tack test
2
with PP probes with PSA-4501 coating (5 and 10 mg/cm ) on glass and backing membranes 9733 and 9735. Results are expressed as mean ± standard
deviation (n = 5). ****p < 0.0001; ***p < 0.001; **p < 0.01; *p < 0.05.

Figure 7. Effect of Pressure sensitive adhesive’s (PSA) viscosity on adhesion. (a) Amine-compatible PSA-4102 displays significantly lower peak adhesive
force compared to PSA-4202 and PSA-4302. (b) Non-amine compatible PSAs (PSA-4501, PSA-4502, and PSA-4602) display no significant difference in
peak adhesive force. Results are expressed as mean ± standard deviation (n = 5). ****p < 0.0001; ***p < 0.001.
