We represent ITW Performance Polymers Inc. - USA for Epoxy Chocking Compound

  1. Superior permanent alignment...assures a significant reduction in damage to crankshafts, crankcases and bearings.
  2. Precise & unsurpassed contact with bedplates...without costly machining.
  3. Free flow of air under hot-running machinery...reduces foundation "humping" problems.
  4. Fast, convenient installation without any time-consuming, expensive hand-fitting...minimal equipment downtime.
  5. Resists degradation by fuels, lubricants & possibility of fretting or corrosion.

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.


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.
