Adhesives, Resins, and Solvents for Repair of
Armor. The following paragraphs explain adhesives,
resins, and solvents used for repair of armor.
(1)
Adhesives.
For
adhesives,
follow
manufacturer instructions concerning storage, agitation,
mixing, thinning, temperature, range, fire and health
hazards, plus contamination by moisture and dust. The
adhesive used for repair can be applied to the fraying
surfaces by any convenient means that will give a
smooth, uniform spread of the adhesive Use methods
such as a brush, a hand roller, an extrusion gun and
squeegee Clean all tools Immediately after each use with
Toluol, TT-T-548. Do not let adhesive polymerize (cure)
before cleaning.
NOTE
Use Polysulfide Sealing Compound,
MIL-S-8802, Class A-2 or B-2 for
adhesive Pro-Seal 890 (FSCM 83527) is
a
qualified
product
meeting
or
exceeding the requirements of MIL-S-
8802. Use Pro-Seal 890, Class B-2 for
application by squeegee or extrusion
gun. Use Pro-Seal 890BT, Class A-2
for application by brush or hand roller.
(2)
Resins. Many tertiary amines, phenolic
materials, alcohols and water catalysts accelerate the
reaction between the Diethylene Triamine (DTA) curing
agent and EPON resin. Although catalysts are used to
control the curing rate of resins, they reduce the pot life
of a mixture formulation, such as DTA and EPON Do not
use any curing agent accelerators Since water is an
accelerator, avoid any contact of the mixture formulation
with water.
NOTE
As
the
room
temperature
decreases the resin curing rate
time falls rapid. The DTA curing
agent may be applied at a
temperature as low as 55°F
(13°C), although the time to reach
a given stage of cure is at least
double that required at normal
room temperature.
The viscosity of the resin may be
too high for some methods of
application. Add methyl ethyl
ketone,
TT-M-261,
up
to
a
maximum of five percent by
weight
of
the
total
solution
content, to lower viscosity.
(3)
Solvents. For solvents and cleaning
solutions, observe all of the usual precautions for
ventilation to prevent the accumulation of toxic vapors
and to avoid a fire hazard.
(4)
Instructions
for
Pro-Seal
890
sealant.
Instructions are as follows:
NOTE
Bonding material Pro-Seal 890
consists of two parts: Pro-Seal
890 Sealant and Pro-Seal 890A
Curing Agent
Both Pro-Seal 890 and its curing
Agent Pro-Seal 890A should be
used as received. Do not thin
with solvent.
Curing
agent
Pro-Seal
890A
contains no solvent to assure a
minimum amount of shrinkage
when mixed with Pro-Seal 890
Sealant. Pro-Seal 890A contains
an
oxidizing
compound,
therefore
avoid
prolonged
contact with the skin. Wash
hands thoroughly before eating
or smoking.
