Main Reasons Insulation is Used
• Protect personnel• Reduce energy cost – ROI• Added benefits
– Control condensation– Improve process control – Improve facility lifecycle costs– Improve work environment
3
Why Insulation is Often Overlooked
• Insulation can create added problems– Corrosion Under Insulation (CUI) is one of the biggest
maintenance issues in facilities
• Poor communication within facility• Unaware of cost saving potential
4
Insulation Found in Most Plant Operations
– Removable/Reusable Blankets
– Calcium Silicate– Perlite– Fiberglass– Closed Cell Foam– Urethane Foam– Ceramic Fiber– Cellular Glass– Insulating Coatings
5
Conventional Insulation – The Good & Bad
Pros• Good thermal capability• Works at high temperatures (> 500°F)• Provides good absorptive type energy
retention
6
Conventional Insulation – The Good & Bad
Cons• Most absorb moisture,
promoting CUI and mold growth
• Requires substantial fabrication (2, 3 & 4 part systems)
• Shorter lifespan• Consistent maintenance issues• Safety aspects• Diminished performance over
time
7
NOTE! Facts About Moisture & Insulation
• Moisture severely limits performance of conventional insulation
• Units running under 316°F (157°C) promote CUI
• Conventional insulation systems may require a separate moisture barrier, which degrades over time
• Between 10% and 30% of insulation in facilities is missing or damaged*
* National Insulation Association

TODAY, NEW TECHNOLOGY SOLVES AGE OLD PROBLEMS
9
Insulating Coatings
• Long lifespan with little maintenance needed
• Rapid application with minimal man hours
• No chance of CUI occurring
• Reflects heat back into source, keeping products and processes more manageable
• May be applied without shutting down operations

LIMITATIONS• Maximum continuing
operating temp of 375°F

SPECIFICS ABOUT INSULATING COATINGS
19
Industrial Coatings
Mascoat
Industrial-DTI – Personnel protection, energy retention, process stability
Industrial-AC – Anti-condensation applications
Industrial-HR – Radiant heat gain applications
Sound Control-dB – Vibration and noise reduction
WeatherBloc – Insulation on buildings and commercial structures
Envirotrol
CC100 – Personal protection, energy retention, process stability
CCX – Similar to CC100, but with maximum operating tempurature of 450°F
20
How the Coatings Work
Combination of irregular & sphere shaped particles
that encapsulate air
Conducted heat is transferred across entiresurface and throughout the particles
Reduced temperature with low heat flux
Radiant heat (Reflected)
Radiant heat (Reflected)
Heat Flux Transmissions (Emissivity + Absorptance +
Transmittance) - Power of the heat (amperage – voltage) is reduced
compared to other insulators.
ConductiveThe coating system blocks all aspects
of heat transmission, not just the conductive aspect found in most
conventional insulators.
ReflectiveMascoat uses all of the blocking
agents to reflect heat. Cross section of Heatand Coating

How Does Heat Transfer?
• Conduction– Anti-conduction
• Convection– Emissivity– Absorption
• Radiation– Transmittance– Reflectivity

HOW CAN THERMAL INSULATING COATINGS BENEFIT PAPER MILL OPERATIONS?
25
Personnel Protection
• Thermal insulating coatings can reduce recordable injuries:– Burns– Slip and fall accidents– Hearing loss– Unacceptable working conditions (heat)
• This also reduces a facility’s:– Paid time-off for injured employees– Medical costs for injuries on the job– Fines levied by OSHA– Meetings about injuries that have occurred
26
Personnel Protection
Through a NACE accredited study authored by a independent coatings expert, we have documentation that has shown that
thermal insulating coating meets and exceeds the ASTM C1055 & ISO 13732-1 standards, i.e. the “5 second/140˚F rule”

New World Benefits
• Insulation reduces a facility’s CO2 and other polluting emissions output.
• When a facility takes steps towards reducing their energy needs, an added advantage is that the facility also lowers the CO2 emissions.
30
Reducing CO2 Emissions• A 3rd party test revealed a 35% increase in energy savings
when 145 mils (3.25 mm) of Mascoat Industrial-DTI was applied to a test unit compared to an uncoated unit.
• This resulted in a 35% reduction in CO2 emissions.

Paper Mills
• Application– No down time due to shut
down
– Smaller crews and less time to complete the application
– Applicable to tight spaces and on moving equipment.
– No risk of overspray, as dry fall is within 3–5 feet
32
Paper Mills
• Maintenance– Prevents CUI from occurring
and removes equipment from CUI programming
– Constant inspectability of substrate
– Excellent weather resistance
– Easily repaired if mechanical damage takes place
33
Paper Mills
• Return on Investment– Conserves energy
– Reduces future maintenance costs
– Personnel protection – reduces recordable injuries due to burns (ISO 13732-1)
– Coating lasts many years longer than conventional insulation
– Helps stabilize internal conditions, reducing energy needs
