Polyglycol Ethers : D046, D047

D047 is the most frequently used antifoam​ Low cost (depends on location)​ Effective in most situation​ D046 is composed of highly absorbent inorganic filler materials treated with liquid antifoam material​ High surface area​ D046 and D047 must be present in the system before mixing​ Not active as defoamer​ D047 should be well dispersed in the mix water (flow temp.)​ Post-addition of D047 may stabilize foam (e.g. D191 systems)​ D046 has to be dry-blended​

D046 and D047 use is not recommended in slurries that contain large amount of salt (more than 2% BWOW)

Silicones : D175A, D206

00:30

Applications: SALTBOND slurries and any systems containing more than 2% salt BWOW In salt-saturated systems: only efficient antifoam agents GASBLOK and WELBOND systems: D175A and D206 are very efficient and must be used

Applications: SALTBOND slurries and any systems containing more than 2% salt BWOW In salt-saturated systems: only efficient antifoam agents. GASBLOK and WELBOND systems: D175A and D206 are very efficient and must be used

00:34

Recommended amounts of D175A / D206 • 1 to 4.5 L/t [0.01 to 0.05 galUS/sk] in SALTBOND slurries. 3 to 10 L/t [0.03 galUS/sk to 0.1 galUS/sk] in GASBLOK and WELBOND slurries. 1 to 1.8 L/t [0.01 to 0.02 galUS/sk] in all other applications for foam prevention. 2.5 L/m3 [0.1 galUS/bbl] in MUDPUSH spacers

B411

• Environmentally- friendly oil-based antifoam agent • Previously coded B411 for use in the north sea • Works as an foam preventer • Effective antifoam with most cement slurry and chemical washes • Does not affect slurry properties • Incompatible with GASBLOK Additives, D600G, D700, D701 • Performance severely altered when used in chemical washes, combination with surfactant D191. Concentration ranges 1 – 5 ltr/tonne (0.01 to 0.05 galUs/sk) of cement
