Benefits/Advantages To Customer
Improved porosity: 3M
™
Venting Tapes offer good porosity for out gassing.
Unique construction: Non-woven backing conforms well, providing an
effective seal. This unique backing has high air and gas permeability, allowing
minimal foaming voids. The backing has good burst strength, which helps
reduce clean-up.
