COMPARATIVE TESTS between silicon adhesives and non-silicone adhesives applied with the GEAR System – SIL method
indicate a greater tenacity of adhesion on silicon, for the adhesives applied with the GEAR System-SIL method, compared to the standard silicone adhesives applied with the traditional pressure method
TENACITY INCREASE with GEAR System-SIL method
from +47% to +91% depending on the type of adhesive

Test method :
test: “T Peel Adhesion ASTM D 1876-01” on silicone rubber samples after 14 days from coupling with 7 different types of adhesives
sample: silicone rubber hardness 70 shore A, section 12×3 mm.
tested adhesive types: silicone – rubber based – modified acrylic – acrylic foam
adhesive height: 10 mm.
elapsed time between adhesivization and testing: 14 days
