Application & Uses
HSC-7755 is a 100% active foam control agent for formulating highly effective antifoam emulsions.
HSC-7755 is effective at very low levels and shows excellent durability to repeated foam generation in aqueous systems. The recommended usage level is up to 0.1 wt% percent based on the formulation at the point in the process when foam is generated. It is preferred to add the antifoam before or while applying mixing or other shear forces.
HSC-7755 is used as a foam control agent in various industrial chemical formulations. This product is characteristically used as the only antifoaming active in strong foaming applications such as pulp and paper, laundry and other high-shear processes.
Uses for HSC-7755:
l Leather finishing: foam control
l Pulp & Paper: Active in defoamers, knockdown enhancer, drainage aid
l Textile: Component of defoamers for knockdown and compatibilization.
l Automotive & household products: Foam control in laundry and other high foaming applications such as carpet cleaners
l Filled or pigmented paints
l HSC-7755 is not generally recommended for clear coatings due to the risk of defects.
l Any non-aqueous industrial process used neat or diluted in solvent.
Key features and benefits:
l Highly effective antifoaming and de-foaming
l Much more effective vs. conventional coating defoamers
l Easy to formulate into stable emulsions
HSC-7755 is also designed to be an active component of water based defoamer formulations, the product needs to be emulsified into water or your foaming system to minimize the side effects and to provide quick knockdown of foam.
How to use
For water based systems, HSC-7755 should be used in a diluted emulsion form.
The suggested emulsion preparation below is in an example only, the stability of this emulsion has not been fully evaluated.
Suggested formulation:

15.0% |
HSC-7755 |
|

Water I |
|
31.8% |
Water II |
|
0.2% |
Thickening Agent e.g Carbopol 941 |
|
0.2% |
NaOH 50% |
|
0.1% |
Biocide |
Procedure:
- Add Thickener to Water I and mix at 450 rpm until dispersed
- Adjust pH to 6.5-7.5 using 50% NaOH
- Add HSC-7755 slowly, mix at 450 rpm
- Add Water II and Biocide
It is important to mix the product prior to use. Particle size of these emulsions is critical to performance. The amount of shear during step 3 is the main factor in affecting this particle size.
For non-aqueous systems, the product can be used neat, but is better used diluted in an appropriate carrier.
Packaging
HSC-7755 is available in 30Kg and 120Kg containers.
