ADHESIVES

GC Electronics offers three basic types of adhesives:

1. EPOXY CEMENTS: Among the strongest and most universal of all bonding materials. They consist of two parts which must be mixed
before applications. Epoxies dry without heat or pressure at room temperature through catalytic action.

2. CYANOACRYLATE ADHESIVES: Do not require the use of an added catalyst, nor heat or pressure. Dries within seconds through
the process of polymerization.

3. SOLVENT-RELEASE ADHESIVES: Resins or polymers in solution. This general category also includes welding type adhesives which
create a bond of exceptional strength.

Two-component, solventless cements which form an exceptionally strong bond (up to 4,000 psi) and they do not shrink on curing.
May be used to cement porous and non-porous substances including all metals, glass, ceramics, most plastics, cardboard, wood, rub­ber, and fiber. They resist moisture, most solvents, acid, and alkalis. The consistency of epoxy is that of semi-fluid or putty. They have
a tendency to “fill-in” and will produce strong bonds even if the parts to be cemented do not match perfectly. Epoxy cures at room
temperature, but elevated temperatures (up to 80°C) may be employed to speed up the curing time. All GC epoxy cements are easy
to prepare as they require a 50/50 composition to be mixed. This can be judged when squeezing out the tube, for the exact ratio is
not critical. The working life, often called “pott life” of the mixture, is the time span from mixing the two parts until the chemical
reaction starts to harden the compound. A product with short working, and correspondingly short curing time, is indicated where a
single repair is to be made and the mixture can be applied immediately after preparation. For production purposes, a type with long
pott life should be selected.

Quik Stik

5 Minutes Set

Clear, fast curing epoxy adhesive. In view of its
short pott life, use is recommended when a
single repair must be made and the mixed
adhesives can be used within one or two
minutes. Cemented items can be safely
handled within eight to twelve minutes, with
full hardness obtained after several hours.

This
cement is relatively thin in consistency and
should be used to cement closely matching
surfaces. The glue line is usually invisible.

Part No. 10-114 Pkg. of two 1/2 fl. oz. Tubes
Part No. 19-822 Double Syringe .0105 oz.

2 Part Epoxy Super Glue

5–6 Hour Set

Versatile epoxy cement particularly suit-
able for cementing non-porous materials.
Cures at room temperature. Bond strength
of over 3000 psi. Will not shrink through
curing. Resistant to water, solvents, heat,
cold and fungus. Excellent dielectric prop-
erties. Mix in equal parts from two tubes.

Part No. 10-100 Pkg. of two 3/4 oz.

Tubes

2 Part Epoxy Glue

5 Hours Set

Provides an exceptionally hard and
strong bond. Good dielectric proper-
ties. Gray-white in color with fillers
added to increase viscosity and make it
thixotropic (non-running). May be used
to fill gaps or to replace broken sec-
tions. Bonds may be over-filled and
filed or sanded after curing.
