CHOCKFAST ORANGE©
Bulletin # 659D
DESCRIPTION:
CHOCKFAST ORANGE (PR-610TCF) is a specially formulated 100% solids, two component inert filled casting compound
developed for use as a chocking or grouting material. CHOCKFAST is designed to withstand severe marine and industrial
environments involving a high degree of both physical and thermal shock. The compound is non-shrinking and has very high
impact and compressive strength. Years of successful in-service experience have shown the use of PR-610TCF to be a far
superior yet less expensive method of establishing and permanently retaining precise equipment alignment under extreme
conditions. PR-610TCF is approved or accepted for its intended marine use by American Bureau of Shipping, Lloyd's
Register, Bureau Veritas, Det Norske Veritas, Germanischer Lloyd and most other major regulatory agencies worldwide.
APPLICATION:
CHOCKFAST ORANGE was developed as a chocking or grouting compound for use under marine main propulsion
machinery. The compound is used under diesel and gas engines, reduction gears, generators, compressors, pumps, bearing
blocks, crane rails and numerous other applications. PR-610TCF requires no special tools or special skills as does chocking
with steel. When cast, CHOCKFAST ORANGE flows readily into the chock area filling voids and conforming to all
irregularities. This eliminates the machining of base plates or foundations for a perfectly fitted chock.
