IMCAS ESP 2 is a unique coating that is specially formulated to seal vacuum leaks. It can be used on turbine condensor gaskets, turbine rupture discs, strainers, manways, hot well covers, condensate line expansions joints, as well as many other areas that present possible vacumm leaks.

INCAS ESP 2 will bond tightly to rubber but will release from metal with a little coaxing. Temperature in areas used should not exceed 250°F.


Outstanding Features:

  • Total bonding
  • Easy to apply
  • Bonds to rubber
  • No halogens or PTFE
  • Liquid applied
  • No Elemental Sulfur





Surfaces must be dry, free of dirt or loose debris, free of oils, greases or any substances that will interfere with bond. IMCAS ESP 2 is applied straight out of the can after 2 minutes of gentle low speed mixing or stirring. Apply the product using brush or roller. It is only necessary to touch the vacuum leak with IMCAS ESP 2. The vacuum will draw it in and cause it to plug the leak.

Spray equipment can be used to reach areas. Caution is advised in using spray equiment. Airless type equipment must be used. The following equipment specifications must be used: 30:1 pump ration or higher. A minimum 3/8" hose with as short of a run of hose as possible. A #37 tip is recommended.

Clean up:

Clean tools and equipment with xylene or toluene solvent. Do not allow any solvent to contact IMCAS ESP 2 that has been applied.



Do not apply to wet or frozen surfaces that are saturated with moisture. Shelf life is 2 years when stored in a factory sealed container between 45°F and 90°F. This product is flammable. Keep away from sources of heat, sparks, and flames. Use only EP rated equipment.
