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.

Product Specification

• *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

• 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

Application Methods

Application Conditions

• Industry standards are for substrate temperatures to be 3°C 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
