Chockfast® Black from UK Marine Resins Ltd


CHOCKFAST® Black is a specifically formulated 100% solids, inert filled casting compound developed for use as a chocking material. It is a cost-effective method of maintaining permanent precise alignment of critical equipment. It will withstand severe environments involving high physical and thermal shock.

Single Pour: 25mm – 60mm
Cure Time: Up to 48 hours at 15°C


This unique product is used under gas and diesel engines, compressors, generators, turbines, motors, pumps and various other types of equipment. CHOCKFAST® Black is ideal for use under these hot running reciprocating and rotating machines because of its excellent resistance to creep and fatigue at high operating temperatures. It is non-shrinking and has a very high impact and compressive strength. Resin chocks made with CHOCKFAST® Black reduce possible bearing or crankshaft damage because they:

  • Minimize heat build-up on foundations
  • Assure precise alignment and unsurpassed contact with bedplates
  • Provide a high coefficient of friction to help hold engines down tight.
  • The excellent flow-ability of CHOCKFAST® Black allows it to fill voids in the chock area and conform to all surface irregularities.
