Gluing Tests - DIPTEM Genova - Adhesives

Shear tests with four different adhesive types:

Adhesive tape

NITTO DENKO 30 µm thick

Adhesive tape

3M 9461P – 30 µm thick

Liquid glue

Araldite 2020

Adhesive film

FastelFilm 30 µm thick

• Polyester film double coated by acrylic adhesive

• Polyester = 0.13-0.15 W/m K

Acrilyc = 0.2 W/m K

• 3M Adhesive 100 (Acrylic adhesive)

• 3M Adhesive 100 = 0.178 W/m K

• Two components epoxy liquid glue

• Epoxy = 0.188 W/m K

• EVA (Ethylene - vinyl Acetate) adhesive film

• EVA = 0.34 W/m K
