Carboline Polyclad 777 Fast-Set 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 snap-set cure mechanism.

Typical uses include steel pipeline exteriors, steel valves andamp; fittings, steel pilings, steel poles (above andamp; below ground), buried tank exteriors, penstocks. No primer is required. Available in snap, fast, medium, and slow set times.

Due to its aromatic composition Polyclad 777 will tend to yellow or darken in exterior UV exposure.
This will not affect performance.

Drying Times

Curing Schedule
Surface Temp Dry to Handle Dry to Touch
24°C 9 Minutes 90 Seconds

  • 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


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

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

Do not batch mix parts A and B

Do not thin.

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 3,000 psi

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