What is the difference between addition potting adhesive and condensation potting adhesive?

The biggest difference between addition potting adhesive and condensation potting adhesive is that condensation potting adhesive has small molecular substances, while addition potting adhesive does not. This determines their performance differences.
The addition molding room temperature potting adhesive is gelled by the addition reaction of silicon hydrogen bond and ethylene double bond under the action of platinum catalyst, and no small molecules are produced during the reaction; The condensation room temperature potting adhesive is a kind of gelled curing adhesive, which uses silica gel and curing agent in the presence of catalyst to condense the active group to remove small molecules.
