Item # EAC, EAC Ceramic Putty

EAC is a brushable and versatile maintenance material, which has excellent resistance to both acids and caustics as well as having excellent abrasion resistance. It is primarily used to resurface any component requiring both abrasion and chemical resistance such as tanks, heat exchangers, valve or pump internals.

Features
  • Excellent chemical and thermal resistance
  • Very good resistance to moderate levels of abrasion
  • Excellent fluid flow characteristics
  • Long term flexibility
  • Excellent resistance to cavitation

Pot Life
For a 1 kg. unit, mix at 70 ºF, pot life is approximately 30 minutes. Higher temperatures or larger mass will shorten this time, lower temperatures or smaller mass will extend it. Pot life can also be extended by spreading the mass out to dissipate heat.
ColorGrey 
Red
StorageStore in dry area in closed containers between 50 ºF and 110 ºF. Shelf life at these conditions is greater than one year.
Coverage
EAC has the consistency of a thick paint and can be applied up to 30 mils per coat. Theoretical coverage at 40 mils is 32 cubic inches per kg. Although one coat will usually provide the required coverage, two or more coats will aid in the control of pinholes and holidays.
Surface Preparation
  • For maximum adhesion, material should be applied to a firm, clean, dry and abraded surface.
  • Best results will be obtained by abrasive blasting the surface.
  • If blasting is impractical, a grinding wheel, needle gun, or very stiff wire brush may be used.
  • Clean greasy, oily or waxed surfaces with suitable solvent before applying material.
Mixing & Application
Mixing
Mix ALL of Part A with ALL of Part B. Mixing may be done in a container large enough to hold both the base and hardener. The selected container must be clean and dry. Mix the material thoroughly until no streaks of any kind are visible. If materials are cold, warm them to 70 ºF before mixing.

Cleanup
All mixing and applications tools should be immediately wiped or scraped clean when finished with using.

Application
EAC is best applied with a stiff bristled brush, squeegee, or the plastic applicator supplied with the kit. Press material thoroughly into substrate and insure a completely wetted out surface. Build up to the required thickness with a second pass. Large cracks or holes should be bridged with glass or metal cloth. Reinforcement should be overcoated.

For best results, do not apply:
  • When temperature is below 40 ºF
  • When humidity is over 95%
  • When there is moisture on the surface
  • When surface temperature is not 5 ºF above dew point

Force Curing
Force cures are recommended for severe service conditions as both the physical and chemical properties are enhanced. Force curing should not start until material has firmly set.

Recommended Force Cure Schedule:
  • 1 hour at 250 ºF
  • 4 hours at 180 ºF
  • 8 hours at 120 ºF

Health and Safety
