WACKER SilGel^® 612 EH A/B

All surfaces must be clean and free of contaminants
that will inhibit the cure of WACKER SilGel® 627 A/B.
Examples of inhibiting contaminants are sulfur
containing materials, plasticizers, urethanes, amine
containing materials and organometallic compounds –
especially organotin compounds.
If a substrate’s ability to inhibit cure is unknown, a
small-scale test should be run to determine
compatibility.

Caution
Only components A and B with the same lot number
may be processed together!

Component B of WACKER SilGel® 627 contains
the platinum catalyst, component A the crosslinker.
Even traces of the platinum catalyst may cause gelling
of the component containing the crosslinker.
To eliminate any air introduced during dispensing or
trapped under components or devices a vacuum encapsulation
is recommended.
