This tutorial will cover Connector Design Guidelines and
Processing for the Connector Sealant Pads.
Dow Corning® Connector Sealant Pads and Sealant Strips provide
sealing and corrosion protection for indoor and outdoor equipment, including
connectors and electrical components. The line of connector sealant pads is
designed primarily for sealing the individual pins, wires and contacts within
connectors. Sealant strips are intended for sealing and protection uses other
than connector pins, such as alternatives to wet dispensed coatings, pottants
and adhesives in protecting electronic equipment or providing low pressure
gasket seals. Dow Corning® Connector Sealant Pads have a drier surface on top
and bottom for easier handling during application. Dow Corning® Sealant
Strips are supplied with at least one side tacky for added adhesion to
surfaces.
There is a separate tutorial containing a general overview of this Connector Sealant Pad product line located
here.
Another tutorial presents a general overview of Dow Corning® Sealant Strips.
And finally, a tutorial on processing of Dow Corning® Sealant Strips.

The connector sealant pad consists of a three-layer laminate. The middle layer
is a soft silicone gel impregnated into an open-cell foam. This combination
of gel and foam provides excellent sealing capabilities under compression. The
silicone gel provides critical sealing and protection properties. The open
cell foam is used mainly as a carrier for the gel and helps to add strength
and dimensional stability. The thin top and bottom layers consist of a harder
gel. This harder outer surface allows easier handling of the pad during
assembly. The connector sealant pad is supplied on a Mylar ® release film to
permit easy indexing in automated processes.
