Color clear (high solids)
V.O.C <52% monomer
Weight per gallon 8.6 lbs/gal
FEATURES
GEL TIME EXTENSION
Slightly slow the catalyzed pot life
by adding COOLSHOT at at 3:1
blend.
COMPATIBLE CHEMISTRY
Designed to work along with the
DuraKote gelcoats and Duratec
polyester primers.
STAY C HILL
Longer gel time makes it easier to
use the gelcoats or primers in
higher temperatures or where
large
amounts will be mixed at one time.
TACK FREE FINISH
COOLSHOT enables gelcoat to
form a smooth, hard surface film.
COLOR NOTE:
Adding 39COOLSHOT to an opaque
coating will reduce the opacity of the
coating. This may cause an apparent
color change.
Before any repair test the mixture to
determine if there is enough opacity to
achieve a satisfactory repair.

S A FE
TY & H ANDL I NG
Duratec COOL
SHOT is extremely flammable. Do not apply near sparks, open flames or
heat. Keep area ventilated. D
o not smoke. Avoid continuous breathing of vapor. Duratec
COOLSHOT contains ingredients
which coul d be harmful if mishandled. Contact with skin
a
nd eyes should be avoided and necessary protective equipment and clothing should be
worn. Individuals
should wash with soap and water before eating or drinking. All containers
should be properly labeled t
o prevent accidental ingestion or improper disposal. Individuals
should reseal any partly
used material back in the container. S tore under cool, dry
conditions
and away from open flames and high temperatures.

more detailed instructions on storage, please see the MSDS sheet.
DE S
CRIPTION
A
n additive designed to accelerate the s urface cure of and overcome the
oxygen
inhibition of the Durakote gelcoat series or other
polyester gelcoats.
I
t can also be used to slow gel time in Duratec polyester primers.
COOLSHOT will increase the gel and cure time by ~1
0% and enables
gelcoat to form a smooth, hard s
urface film.

APPLICATION INSTRUCTIONS
5.Spray pressures should be 35-50 PSI. If pressure pot is used, provided 10-15 psi
pot
pressure.
6.Spray the entire surface
to be repaired with a fine mist coat, and wai 2 minutes
for t
he solvents to fl off.
7.Fol
low with wet coats, overlapping the surroundi
ng area to ensure complete
coverage. When re-spraying large areas, keep a wet edge with a sta
ndard
gelcoat spray technique.
8.When the material has cured (~1 hour), lightly sand with
320-800 grit wet or dry
sandpaper. Allow coating to breathe
for at least another hour after sanding.
9.After open breathi
ng period, buff surface to desired finish. AquaBuff 1000F
Fast-Cut Compound and
AquaBuff 2000 Polish is recommended.

1.39COOLSHOT is ready to use as received.
2.Thoroughly sand the area to
be repaired to a 120 or 180 grit finish. Ensure
surface is cleaned well to remove a
ny contaminating substances. Select a high
quality gelcoat of the appropriate color. We recommend a small gel time
mixture be done to determine specific gel time for existing shop conditions.
3.Add COOLSHOT R

gelcoat
prior to use. Thoroughly mix before using.
4.Catalyze the combined mixture as recommended, at 2% by weight with MEKP
(Norox 925 is a good choice.) Mix thoroughly.
*39COOLShot will reduce the gel coat or Duratec. If additional thinning is needed, thi n 5% by weight with
Duratec 39UCE, MEK,
or virgin acetone.

World Class Coatings
Technology 12% COBALT OCTOATE
____________________________________________________________________________________________
DURA TECHNOLOGIES, INC. 12% Cobalt Octoate is a primary drier. It is an
oxidation catalyst and acts as a surface drier. It accelerates the catalytic action of Methyl Ethyl
Ketone Peroxide to polymerize unsaturated polyester resin.
The shelf life is 60 months from the date of manufacture.
Additive Characteristics:
Appearance: Redish purple liquid
weight per gallon: 8.3 lbs
V.O.C. 309 grams/liter
Application:
1. 39COBALT is ready to use as received.
2. Use up to 1 percent by weight to the adjust the gel and cure of unsaturated polyester
resins. The amount required will vary with the age and type of resin
3. Add to the resin while mixing and continue to mix at low speed for 30 minutes.
4. METHYL ETHYL KETONE PEROXIDE (M EKP) is the recommended catalyst
although other peroxides will work.
WARNING:
DO NOT ALLOW THE PEROXIDE TO COME INTO DIRECT CONTACT WITH
THE COBALT. THE TWO MATERIAL WILL REACT VIOLENTLY AND WILL
EXPLODE.
