Description

Carboline Polyclad 777 Slow-Set is a two-component, solvent-free aromatic polyurethane, ASTM D16 Type V. A high performance 100% solids structural polyurethane coating 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 snap-set cure mechanism. Typical uses include steel pipeline exteriors, steel valves and fittings, steel pilings, steel poles (above and below ground), buried tank exteriors, penstocks. No primer is required.

Available in fast, medium, and slow set times.

  • *Adhesion over 3,000 psi is common with high peak count, surface cleanliness and good adhesive. Preferred adhesives for running adhesion testing are 3M CA-100 and 3M DP-460



Drying Times


Curing Schedule
Surface Temp Dry to Handle Dry to Touch
24°C 22 Minutes 7 Minutes



  • 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
  • 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:

Steel or ductile iron

Remove dirt/dust/grease/oil following SSPC-SP1

Abrasive blast to SSPC-SP10

Achieve a 75-125 micron "angular" anchor profile

Ensure dust/smut from blasting operation does not interfere with adhesion, prefer two maximum on ISO 8502-3 test

Apply product prior to any flash rusting or contamination fallout



Application Methods


Product Information
Mixing:

Power mix part B until the pigments are dispersed into a homogeneous liquid

Do not batch mix parts A and B

Do not add thinner

Airless Spray:

Use only heated plural component airless equipment

Plural airless pump must have a 1:1 ratio capability along with 1.25 gallons per minute with a fluid pressure up to 3000 psi

Use a paint system setup that can transfer coatings from heated drums to the proportioners and maintain heated material to the spray tips
