Hypax Oxidate Esters
The Hypax series of Oxidate Esters and Ba.,Ca., salt derivatives
are designed to combine rapid water displacement of free and
adsorbed water from metal surfaces and deposit a thin continuous
barrier layer which will provide temporary protection to polished
metals exposed to atmospheric pollutants.The A3 series will
demulsify Caustic solutions and leave a clear interface between
the protective and aqueous layers.
Hypax 150 A3 ,2180 BSB and 600 CA3 have reserve alkalinity
to inhibit the permeation of acidic vapours through the protective
layer. A schematic of the mode of operation is demonstrated
below.The products also function as viscosity depressants
and flow additives for rheologically structured sealents.
| Mechanism of water displacement |
|
|
| A: Displacing fluid applied to
water surface. Mixture with water begins. |
|
|
| B: Fluid reaches metal surface
while pushing water aside. |
|
|
| C: Preferential adsorption of
the fluid over water allows water to be displaced
from the surface. |

Note: Demulsification is determined using a 15 % w/w of ester
solubiloised in dearomatised solvent mixed with an equal amount
of 5 % NaOH sol.The time taken to obtain a clear interface
is recorded.
