Inhibition Concerns

Although generally considered to be non-corrosive to most substrates, the oxime cure system may cause discoloration in the presence of copper or copper alloys. Note: Some bonding application may require the use of a primer. NuSil Technology SP-120 silicone primer is recommended.
