KOPATCH PC270
AMINE CURED EPOXY COATING FOR REPAIRING
KOPATCH PC270 is two components, amine cured epoxy based coating with excellent adhesion,
anticorrosion resistance, high build, solvent free coating for use on steel substrate. Widely used as a repair
for protection of internal and external pipelines.
(Maximum Operation Temperature : 150℃)

Color Grey
Thickness 1 Coat System : Min. 600㎛
Solids Content 98±2% (by Volume)
Theoretical Coverage Rate 1.7m2 @ 25oC (600㎛)
2. SURFACE & SUBSTRATE PREPARATION
• Surfaces must be clean and dry. Employ adequate methods to remove dirt, dust, oil and all other
contaminants that could interfere with adhesion of the coating.
• Roughen or grind the surrounding area to reach out to the steel substrate.
• Feathered out the parent coating one centimeter around the area that requires to be repaired.

16oC 20 hours 2 days 1.5 hours 4 hours 96 hours
24oC 3 hours 1 day 1 hour 2.5 hours 36 hours

48oC 1.5 hours 12 hours 1/2 hours 1 hour 18 hours
60oC 1 hour 8 hours 1/3 hours 2/3 hours 12 hours
These times are based on a DFT 600㎛. Higher film thickness, insufficient ventilation or cooler temperatures
will require longer cure times. Condensation on the surface or humidity above 25% during application and curing
will result in a surface haze or blush. Any haze or blush must be removed by water washing before recoating.
During high humidity conditions, it is recommended that the application be done while temperatures are
increasing. If the maximum recoat time is exceeded, the surface must be washed with solvent, then abraded
by sweep blasting prior to the application of additional coats.
All data are based on laboratory testing and practical experience.

Minimum 10oC 10oC 10oC 0%
Maximum 50oC 60oC 60oC 90%
Application Conditions
This product simply requires the substrate temperature to be above the
dew point. Condensation due to substrate temperature below the dew
point can cause flash rusting on prepared steel and interfere with proper
adhesion to the substrate. Special application techniques may be
required above or below normal application conditions.
① Thoroughly mix combined parts into a uniform color
② Thinning - Not recommended
Mixing & Thinning ③ Pot life : Approx. 10 min. @ 24oC
Pot life ends when material begins to thicken and starts to heat up.
Pot life times will be less at higher temperatures
Storage Store indoors
Storage temp. & Humidity 4~40oC (0~100% Relative Humidity)
Packaging 50 and 400ml Cartridge
Shelf life 18 months
