SPECIFICATIONS
Protecto-Coat 900/905
shall be 30-40 mils thick, flake filled novolac vinyl
ester coatings, consisting of a basecoat and topcoat of
15-20 mils each, as manufactured by Dudick, Inc. Materials
shall be brush, roller or spray applied in accordance
with the manufacturer’s recommended practices.
PROTECTO-COAT 900 COATINGS AVAILABLE
Protecto-Coat 900 is a higher cross-link
density coating and offers the best solvent and acid resistance.
Protecto-Coat 905 provides improved protection
against fluorides and higher caustic concentrations. Graphite
fillers also provide conductive properties when required
or specified.
|
PROTECTO-COAT 800/805 SYSTEM
Protecto-Coat 900/905
uses two layers of thermosetting, flake filled novolac
vinyl ester resin to build up the protection that steel
and concrete need in chemical manufacturing or processing
operations. When fully cured, the separate elements
lose their individual identity and become a single,
monolithic coating.
Primer 27 is designed to prevent abrasive¬
blasted steel from developing rust bloom prior to the
application of a Protecto Coat 900/905 systems. For
maximum performance, all metal surfaces should be primed,
but primer may not be needed for mild, non immersion
service. Concrete must be primed to aid in the “wetting
out” required for good bonding.
Primer 27C is designed for applications on concrete
where spark testing is required or specified.
Basecoat/Topcoat: Protecto-Coat
900/905 systems are filled with flakes or graphite
flakes to reduce the coefficient of expansion, and provide
a chemical resistant barrier. The overlapping leaf arrangement
of flakes reduces water vapor permeation and permits
chemical exposure at higher temperatures without increasing
the thickness of the coating.

Metal: Metal surfaces
must be abrasive blasted to an appropriate finish.
Immersion and heavy spillage service: White Metal, SSPC
SP-5 or NACE #1, minimum 3.0 mil profile. Heavy non immersion
service (i.e. fumes and spillage): Near white, SSPC SP-10
or NACE #2, minimum 2.0 mil profile. Atmospheric service:
Commercial SSPC SP-6 or NACE #3, minimum 2.0 mil profile.
Concrete: Concrete must be prepared mechanically
to remove surface laitance. Oils, grease or other contaminate
must be removed prior to surface preparation. Concrete
must be free of curing compounds and form release agents.
Surface texture should be similar to 40-60 grit sandpaper
or the visual standard, CSP-5 from the International Concrete
Repair Institute with pea gravel exposed.
The prepared surface should have a nominal tensile
strength of 250 PSI per ASTM D-4541.
All concrete substrates must be checked for moisture
prior to product application using the Plastic Sheet
Test, ASTM D-4263.
Additional surface preparation will be required if a
40-60 grit texture with exposed pea gravel is not achieved
and the surface laitance not completely removed with
the first mechanical preparation.
Mechanical preparation removes laitance, exposing honeycombs
or voids beneath the surface which must be filled with
Scratch Coat 800. (Refer to separate product bulletin)
|
Substrate temperature for both
concrete and metal must be between 50ºF and 110ºF.
Relative humidity must not exceed 90%.
Substrate temperature must be 5ºF above the Dew Point.

Pot life of the mixed Protecto-Coat 900/905
will depend on the temperature. To prevent material
waste and avoid damage to equipment, do not mix more
material than can be used according to the following

Do not attempt to store mixed material. Residual material
should be properly disposed of at the end of each work
period. |
Metal: For maximum performance,
prime all metal surfaces with Primer 27,
mixed with the correct amount of PH-1 Hardener.
Apply at 3-4 mils WFT with a brush, spray or roller.
For mild non immersion service, priming of metal may
be omitted. The basecoat must be applied before rust
bloom occurs.
Concrete surfaces must be thoroughly
dry before the application of the primer. All concrete
must be primed with either Primer 27 or 27C
at 3 4mils WFT. Do not allow the primer to puddle.
Primer 27C must be mechanically mixed
for 1-2 minutes prior to adding the correct amount
of PH-1 Hardener; apply using roller
only. Use brush application for touch up or repair.
|
Mix the Protecto-Coat
900/905 separately to redisperse pigments and
fillers, which have settled. Then, add the correct amount
of PH-1 Hardener to the Protecto-Coat
900/905 and mix thoroughly until a uniform
color is achieved.
Apply at 15-20 mils WFT using a brush, spray or roller
to an even, smooth finish. Allow the basecoat to cure
until “firm” or slightly “tacky”
before applying the topcoat.
In order to prevent curing problems with styrenated
products, air movement and/or ventilation must be maintained
not only during application but also after application
until the system has totally cured. This will prevent
high concentration of styrene inhibiting/retarding the
cure of the system.
|
Standard Formulation:
Use conventional air spray equipment with a pressure
pot: Binks #18 spray gun with #68 fluid nozzle and #68
air nozzle, or Binks #62 spray gun with #68 fluid nozzle
and #68 air nozzle are recommended.
Plural Component: Use a Binks 8 to
1 Pump, and Binks Model 18 NC spray gun #59 BSSX9 47
with a 102 3430 ACI valve. Catalyst should be supplied
by a 101 5202 catalyst tank; 1/2” ID material
supply hose is recommended.
Brush or roller application may require additional coats
to meet the specified dry film thickness.

Protecto-Coat 900/905 must be recoated within 6
hours when exposed to direct sunlight.
If these recoat times are exceeded, consult a Dudick
representative; sanding or abrasive blasting may be
required before the next coat. Recoat times are dramatically
reduced when the coating is exposed to direct sunlight.
Application of Protecto-Coat 900/905
in direct sunlight may lead to blistering, pinholes,
or wrinkling due to out-gassing of air in the concrete
and high substrate temperatures. Double priming, shading,
or evening application may be required. Consult a Dudick
representative.
|
Where immersion service is required, spark
test the coating with a 5000 volt AC spark tester. Mark
and repair all pinholes, using Protecto-Coat 900.
Retest only the repairs.
Protecto-Coat 905 cannot be spark tested.

CLEANING
Use S-10 Cleaning Solvent to
clean tools and equipment. DO NOT USE ACETONE.
