## 4 Results and Discussion  
### Viscoelastic Adhesion Strength  
(1) VG-1 Specimen  
The measurement result of the peeling load (N) of the VG-1 specimen is shown in Table 5, by 10 points (30, 40, 50, 60, 70, 80, 90, 100, 110, 120 mm points) for 3 samples. The peeling load (N) and their average load of 204.3 N were derived. The viscoelastic adhesive strength obtained by dividing the average peeling load value by the attachment width of 10 mm was calculated as 2.04 N/mm. (2) VG-2 Specimen  
The measurement results of the peeling load (N) of the VG-2 specimen are shown in Table 6, by 10 points (30, 40, 50, 60, 70, 80, 90, 100, 110, 120 mm points) for 3 samples. The peeling load (N) and their average load of 204.3 N were derived. The viscoelastic adhesive strength obtained by dividing the average peeling load value by the attachment width of 10 mm was calculated as 2.64 N/mm. (3) VG-3 Specimen  
The measurement results of the peeling load (N) of the VG-3 specimen are shown in Table 7, by 10 points (30, 40, 50, 60, 70, 80, 90, 100, 110, 120 mm points) for 3 samples. The peeling load (N) and their average load of 204.3 N were derived. The viscoelastic adhesive strength obtained by dividing the average peeling load value by the attachment width of 10 mm was calculated as 2.34 N/mm. \begin{table}

The measurement results of the peeling load (N) of the VG-4 specimen are shown in Table 8, by 10 points (30, 40, 50, 60, 70, 80, 90, 100, 110, 120 mm points) for 3 samples. The peeling load (N) and their average load of 204.3 N were derived. The viscoelastic adhesive strength obtained by dividing the average peeling load value by the attachment width of 10 mm was calculated as 0.95 N/mm. (5) Consideration of viscoelastic adhesive strength of NHV-SPRG  
The measurement result of viscoelastic adhesive strength showed highest values in the order of VG-2 > VG-3 > VG-1 > VG-4 from a quantitative point of view. Through this experiment, the viscoelastic adhesive strength of the four materials showed adhesive strength of VG-4 was lower than that of the other three materials, but the average strength was 1.99 N/mm.
