Application Engineer FAQ
A structured brief from SCITEO covering physical properties, application standards, and related specifications.
Single or two-component?
The SC2620 series covers both: two-component (ambient or heat cure, with mixing and pot-life limits) and one-component (no mixing, heat-cure triggered). Select by line conditions.
What hard-to-bond substrates?
Military Cu plating and PTFE defeat most adhesives and then fail cold/thermal shock. SC2620 bonds PTFE when used with SCITEO's specified surface activation process, without creep or corrosion.
