Coating Type
Epoxy / Urethane
|
| |
Description
Used for coating of girth welds, as well
as valves, fittings, pipe, ballast tanks,
ships and marine structures. Ideally suited
for coating of pipe to be used for slip
bore/directional drilling due to its superior
abrasion, impact and gouge resistance properties.
Also for exterior coatings of pipelines
in buried or immersed services. Advantage:
excellent adhesion to grit blasted steel
surfaces, Fusion Bond Epoxy and Fiber Reinforced
Plastic.

PRODUCT
DATA SHEET SP-2888. R.G.
DESCRIPTION: SP-2888. R.G.
is a range of surface coatings based on "State
of the Art"
epoxy / urethane chemistry. The urethane polymer
is pre-bonded to the epoxy resin
rendering the coating "isocyanate free".
The synergistic effect of co-polymerizing
epoxy and urethane produces a coating with
the superior adhesion and permeability of
epoxy along with the added toughness and abrasion
resistance of urethane.
SP-2888. R.G. is available
in Brush Grade and Spray Grade. SP-2888.
R.G. is also
available in Cartridges for coating repairs

Council)
Profile : 2.5 mils minimum

RE-COAT INTERVAL: @ 25°C (77°F)
- Maximum: 4 Hours
@ 100°C (212°F) - Maximum: 20 Minutes
Sweep blasting of the surface is required
if the maximum re-coat interval is exceeded.
Small areas = 316 sq. cm. (= 49 sq. in.) may
be sanded using a medium grit (80-100) carborundum
cloth. All dust from the sanding or blast
roughening must be removed from the surface
prior to the application of the coating |

The
acceptable substrate (metal surface)
temperature range for the application
of SP-2888® R.G. is 10°C (50°F)
to 100°C (212°F). Preheating
of the substrate is required if the
surface to be coated is below 10°C
(50°F). The substrate temperature
must be a minimum of 3°C (5°F)
above the dew point temperature before
proceeding with the coating operation. |
