PROTECTIVE LINING FOR SUPERIOR CORROSION AND HIGH TEMPERATURE RESISTANCE WITH EXCEPTIONAL FLEXIBILITY AND TOUGHNESS

Description

PowerLine® coating is specially formulated with Siloxirane® polymer resin for handling the high temperature and abrasion requirements of the power industry. PowerLine® is a two-component force cure system that offers unique characteristics. PowerLine® is a cross-linked organic-inorganic multifunctional polymer coating that is cured though homopolymerization. This dense crosslinked polymer exhibits high flexibility and toughness, having no detrimental hydroxyl or ester groups. Due to PowerLine’s temperature resistance (500° F/260° C), it provides superior resistance to:

• Acids, alkalis, solvents, oxidizing agents
• Thermal shock -40° F (-40° C) to +500° F (+260° C)
• Flex stressing
• Wear and abrasion
• Impact

Application Highlights

• Resists fly ash abrasion
• Low coefficient of thermal expansion
• Very high bond strengths 5200 PSI on grit blasted steel
• Smooth, low surface energy reduces fly ash buildup in ducts and stacks
• Applied to pitted corroded steel
• Very low VOC - 108 grams/L (0.9 lbs.per gallon)
• Outstanding flexibility
• Non-permeable
• Steam cleanable
• Resists hydroblasting
• Repairable
• Sunlight resistant
• Coefficient of thermal expansion equal to stainless steel
• Resists high voltage

Industry Applications:

• Stacks
• Chimneys
• Ducts
• Flu gas desulfurization scrubbers
• Chemical scrubbers
• Pre-scrubbers
• Spray towers
• Fans

Application Data
Note: Detailed instructions are provided separately for PowerLine® coating systems.

Surface Preparation
Grit blast to SSPC10 (Sa 2.5). Three to four mil (75-100 micron) blast profile most desired.

Mixing Instructions
Material is supplied in two containers as a unit. Always mix a complete unit in the proportions supplied. (1) Thoroughly mix the contents of Part A with a power agitator until uniform consistency and color is obtained. Be sure that any solids that may have settled through storage have been put back into suspension. (2) Slowly combine the contents of the activator with the previously mixed Part A. (3) Thoroughly mix the two parts until a uniform consistency and color is obtained.

Clean Up Solvent
Acetone, Toluene, Tylene

Limitations
Apply when the air and surface temperatures are above 60°F. Surface temperatures must be at least 5° F above the dew point. For optimum application properties, bring material to 70-90° F prior to mixing and application. Increased temperatures will result in shorter pot life.

Application
Airless spray equipment with 60:1 pump ratio @ 80-100 lbs. to achieve 2500-3000 p.s.i. tip pressure. Reverse-A-Clean tip .019 to .023, with 3/8” fluid hose, 3/16” by 6’ whip hose, with a maximum of 100 linear feet. This coating is a low VOC compliant material. If shop conditions require a viscosity adjustment, thin with Toluene or Xylene.

Cure Time And Temperature
Curing: Blow air over lining for 2 hours to remove solvent prior to curing. Raise temperature of metal substrate 50° F per hour. Maintain at 350° F (177° C) for 4 hours.
(See full Specification for Application of PowerLine®)

Coverage
Practical at recommended film thickness (12-14 mils DFT) - 75-80 square feet per gallon.
