One & Two Component Epoxy Systems
|
 Epoxies are the most widely used
polymeric materials for adhesives, sealants, coatings, pottings
and encapsulations and impregnants. They are available in both
one and two component systems. Two part systems can be cured
at either room temperature or elevated temperature. One part
systems must be cured at elevated temperatures (typically 250
- 300°F). One part systems curable by UV light are also available.
 Epoxies offer unique versatility
in application and performance. Their most desirable properties
include high bond strength to a wide variety of different substrates,
outstanding gap filling capabilities, excellent electrical insulation,
high chemical inertness and outstanding resistance to shock and
vibration. Special formulations are available including systems
with thermal conductivity (electrically insulating) for heat
dissipation, electrically conductive systems, systems for cryogenic
applications, as well as systems with high performance in the
most hostile environmental conditions. Viscosities and cure times
can be tailored to meet specific application requirements.

UV Curable Systems
|
 Master
Bond Inc. has available a fast growing family of one component
UV curable polymer systems for high performance coatings, adhesives,
sealants, potting and encapsulation. They include polyurethanes,
epoxies, polyesters and acrylics. They vary in thicknesses, hardness,
chemical resistance, strength, clarity, etc. When exposed to a
suitable UV light source, UV curable compounds usually cure in
a matter of seconds. The Master Bond products are not oxygen inhibited
and cure at ambient temperatures. Environmentally friendly, they
are 100% reactive liquids which do not contain any solvents or
other volatiles. Upon cure they exhibit minimal shrinkage. Additionally,
they are strong, durable, and offer superior temperature and chemical
resistance.  If
required, special formulations can be developed to best meet specific
product application and performance needs. One new "dual
cure" compound can be cured by exposure to either UV light
or heat.
Master Bond UV curable compounds are one component systems
and require no mixing. They have a long shelf life when stored
at ambient temperatures in the absence of UV light. They have
excellent bond strength to metals, ceramics, many plastics and
most rubbers. UV curable compounds are particularly suitable
for automated continuous manufacturing processes because of their
fast cure speeds. |
Anaerobic Adhesives/Sealants
|
 Master Bond’s anaerobic adhesives/sealants
are single component polymer compositions which harden at room
temperature between steel, aluminum, copper and most other metal
surfaces. They cure in the absence of air. The compounds are
available in a variety of thicknesses, cure speeds, strengths,
temperature and chemical resistance properties. They require
no mixing and contain no solvents.
 Master Bond anaerobics are primarily used
as threadlockers. They prevent screws, nuts, bolts and studs
from loosening due to vibration, impact or shock. Anaerobic systems
eliminate the use of lock washers and various other fastening
devices. These adhesive compositions also retain and seal bearings,
bushings, seals, keys and splines. Assemblies are securely and
permanently sealed against corrosion and leakage.

Cyanoacrylate Adhesives
|
 Cyanoacrylates are single
component “instant curing” solvent free adhesives.
They cure upon exposure to moisture at room temperature. These
adhesives are fast and easy to use. They do not need any mixing
or heat and require only contact pressure to obtain durable high
performance bonds. Cyanoacrylates perform best when applied as
a thin film between two surfaces.
Master Bond cyanoacrylates are available ethyl, methyl and
speciality grades. The different grades vary in viscosity, cure
speed, strength, etc. They will bond to almost any combination
of dissimilar and similar materials including metals, rubbers,
most plastics, glass and ceramics. Primers are available to further
enhance cure speed and adhesion to certain hard to bond plastics.
Master Bond cyanoacrylates are easily applied both manually and
automatically. Rapid cure and easy application make them particularly
suitable for high speed production applications. One pound of
adhesive properly applied can provide for as many as 30,000 bonds. |
One & Two
Component Silicone Systems
|
 Silicones are elastomeric systems
with the unique combination of flexibility and high temperature
resistance. They can be used as adhesives, sealants, coatings
and potting materials. Silicone systems are either one or two
part. One part systems cure by moisture in the air. Two part
systems are cured by the polymerization reaction that occurs
when a curing agent is added. Generally, the two part systems
can cure in thicker sections than the one part systems.
Aside from temperature resistance and inherent high flexibility,
other noteworthy properties of silicones include excellent resistance
to water, superb electrical insulation properties and sealing/adhesive
properties particularly to glass, plastics, metals and rubber
(including silicone rubber itself). Their inherent flexibility
allows for “repairability” when this property is needed.
Master Bond offers a number of specialty type systems including
one part conformal coatings, special fast curing systems, higher
temperature resistant specialty systems, thermal conductive systems
as well as transparent silicones. |
Film Adhesives & Preforms
|
 Master Bond Inc. manufacturers a line of epoxy
film adhesives and preforms. These newly developed formulations
include electrically conductive and thermally conductive compounds
as well as structural adhesive films. The cured epoxy products
offer excellent bond strength to both similar and dissimilar
substrates along with high moisture and chemical resistance.
They have fast cures at moderately elevated temperatures and
long storage stability even at ambient temperatures, although
refrigeration is preferred.
 Master Bond epoxy films and preforms are easy to use, enhance
productivity, simplify handling and reduce waste. They are applied
as a solid, have no pot life restrictions and are environmentally
friendly. When heated, the adhesive cures in place and squeeze
out is avoided. Films are available in thicknesses of 2 to 8 mils
and up to 16 inches square. Preforms can be laser or die cut to
the configuration of any part. Both performance and processing
characteristics are reproducible from lot to lot.
Master Bond’s experienced technical staff can custom formulate
