Description

Carboline Polyclad 777 PL is a two-component, high performance 100% solids structural polyurethane designed to provide superior corrosion protection for steel, ductile iron, and concrete pipe. Tenacious adhesion and high impact resistance allow its use in the harshest environments. It forms a dense, long-term impermeable barrier that is ready for service moments after application through a fast-set cure mechanism. No primer is required.

Drying Times


Curing Schedule
Surface Temp Dry to Handle Dry to Touch Cure for Service
24°C 15 Minutes 120 Seconds 1 Hour



  • Lower metal temperatures will slow the dry time and higher metal temperatures will speed up dry time
  • Product is ready for holiday testing as soon as it reaches its dry-to-handle state
  • It is ready for service when the hardness reaches Shore D 70 (typically 1 hour)
  • Maximum recoat time with Carbothane series is 28 days
  • To topcoat past the maximum recoat time, the surface must be abraded and cleaned
  • Maximum recoat with itself is two hours



Surface Preparation


Preparation
General:

Prepare surface as noted below

Ensure dust/smut from blasting operation does not interfere with adhesion

Recommend using ISO 8502-3 to confirm low surface dust with a preferred rating of "1" or "2"

Apply coating prior to any flash rusting or contamination fallout

Steel:

Remove all contaminants in accordance with SSPC-SP 1

Near White Metal Blast clean in accordance with NACE No. 2/SSPC-SP 10 and create 3-5 mils, (75-125 microns), of dense angular anchor profile

Ductile or Cast Iron:

Remove all contaminants in accordance with SSPC-SP 1

Abrasive blast clean in accordance with National Association of Pipe Fabricators, Inc., NAPF 500-03-04



Application Methods


Product Information
Airless Spray:

Use only heated plural component airless equipment with 1:1 mix ratio. The plural airless pump must have a minimum capability of 1.25 gallons per minute with a fluid pressure of up to 3,000 psi

The recommended spray system is a Graco Reactor or WIWA PU 460 plural component system utilizing typical transfer pumps to supply both the resin and catalyst to the spray system, in-line heaters capable of heating the material up to 160°F as needed, heated hose bundle, and a Graco Fusion Plural Component Gun. Other equipment of equal capabilities may suffice

Contact Rawlins on Tech - 0113 2455450 (option 2) or [email protected] for alternate spray equipment recommendations. We recommend that the applicator perform a mock up prior to and after mobilizing to the jobsite to be sure all equipment is performing properly

  • Industry standards are for substrate temperatures to be 3°C (5°F) above the dew point
  • Caution: this product in the liquid stage is moisture sensitive and needs to be protected from high humidity, dew, and direct moisture contact until cured to a firm state. Application and/or curing in humidity above maximum, or exposure to moisture from rain or dew may result in a loss of gloss, micro bubbling and/or blistering of the product
  • Note: for applications on concrete, please contact your Rawlins on Tech - 0113 2455450 (option 2) or [email protected] for proper application procedures
